Hi there. Please help. I followed this tutorial to the letter, and when I try to include the headers in the main.c file, for instance #include, it shows a little icon on the left that looks like a lightbulb with an exclamation mark, and the code won't build. When you float the cursor above the icon, it says: "Cannot find include file , For extra info hold control and move mouse over included directive"
I tried following the prompts, and it didn't help.
Please help. Is there an easy fix?
Hi. Did you install the XC8 compiler? Which version of the XC8 compiler did you install? Which PIC model?

What program do you use for the simulations?? Kind regards Melvin
Hi. We used Proteus. It's from labcenter.com
the compiler didn't build the program until i defined " _XTAL_FREQ ", How did you build it successfuly without useing this function ?
العربي الأصيل You must watch carefully that video because we did use that function and it's explained in the video
Seems that some parts are missing, e.g. after MPLAB XC8 for Beginners Tutorial -22 its MPLAB XC8 for Beginners Tutorial -32 where is from 23 to 31? Even as a beginner its easy to understand and follow
Yes. They will be uploaded in due course. Just subscribe to our TH-cam channel and you'll be notified when we upload new tutorials.
In the meantime you can get more info on our website. They'll be also extra videos and tutorials on our online store
Start from the beginning. More info on our website
what if we use external occilator? and LATB for P18 Then what for P16 Series??
Yes, you can use an external oscillator, in the configuration bits window, select either XT for Crystals of 4MHz or below or HS from 4MHz and above.
If you use newer enhanced mid-range PIC16 series, you can still use the LAT register but for older ones like the PIC16F877, you will have to use the PORT register for reading and writing.
I have downloaded and installed the latest versions of MPLAB X and the C compiler XC8. When I do the build on the code in this tutorial I get the messages that TRISBbits and LATBbits are not defined. Can you tell me which include contains these definitions?
Hi Larry Poorman did you set the configuration bits correctly of the PIC you used? did you include these configurations? Paste the screenshot of your code so we can have a look what could be the problem
Ashwani Garg What kind of errors are u getting? did you use the same PIC that we used in this tutorial? Did you set correctly your configuration bits?
Larry Poorman
Try this insted of TRISBbits-----> TRISBbits.TRISB0 = 0
Thanks. This is a great video. Can you do more video?. ADC, Interrupt, timer, counter...
Please.

Great tutorials I have everything working with MPLABX and Xc8 and my PIC16f1823 but what's the IDE you are using to do the situation is it free where can I get it :)
pier shaw It's called Proteus. It's a great tool for Microcontrollers simulation. unfortunatly it's not free, but there is a limited free demo version that you can download from their website: www.labcenter.com/index.cfm
Oh thank you I found it it's great
pier shaw you are welcome!
question, is the MPLAB XC8 free or is only free for 60 days? Good job on the video. Thanks
+James Cullins Thank you for watching our videos.
MPLAB has two types of licences. Free license and professional license where you need to buy the license. The free version is absolutely free with no time limit or code size restrictions. The difference from the professional version is the code optimization. The generated Hex code of the professional version might be a bit smaller in size than the free version. For small and medium project you might not see much differences.
When you install XC8 for the first time it will give you the professional features for 60 days after that it will become like the free version.
Thanks, with a little reading I found that on their web page. How does it compare to MikroC for PIC compiler? I have it.
Thank you for your quick response, keep up the good work.
+James Cullins The difference in terms of functionalities or price?
If you mean in terms of price, as we explained earlier on, with xc8 free version there is no time limit or the size of the code you can compile.
With mikroC there is also no time limit but the free version allows you to compile only a code which is 2Kb or less in size. So if you have a long code or a code with floating point or long variables with mikroC you won't even compile your code. It will give you an error message: Demo limit.
I was wondering about the functionality .
Thanks so much for the quick responses.
+James Cullins it's all depends from user to user. As mplab xc8 is manufacturer's compiler it'll akways guarantee you to support all devices and all features. Everything the device can do you'll be able to implement with MPLAB. With their new code configurator add on tool, makes it easy to configure peripherals. MPLAB libraries for Application helps you to configure advanced and complex peripherals.
On the other hand, MikroC tends to make everything easy. You'll find it easy to use mikroC as a beginner then mplab because they supply you with tons of libraries to access many peripherals or control external devices. The drawback is that their libraries are embedded into their compiler. You cant edit or view them and they try to simplify everything and not supporting all features. So for some applications you might be stuck.
But the choice is yours depending on your level of programming and what you are designing or plan to design.
I'll be using PIC16F628A.. do you also have tutorial for Pic16f?
marhsall 27777 We don't have tutorials for the PIC16F series, because the logic is the same. If you understand one PIC, you can be able to program another model. All you have to know is the registers available in your PIC, like the PIC16F don't have the LAT register but the rest is not much different.
multitasking RTOS with PIC18 with mplab xc8 all i cant find on internet more. please make a series on this also.
We will look at the them in the future. RTOS is easier to implement with PIC32 than PIC18F.
Thank you for the tutorial, it is very clear and interesting. Could you recommend me a book where I can read details about what you are explaining in your tutorial, for example: ports management, interruptions, ADC, etc.
Thanks for watching our videos and for your feedback. There are many books we are reading, but to get the details of port management and other registers the best is to read the PIC datasheet. No book can explain in detail compared to the PIC datasheet.
For books we sometimes use the books by professor Dogan Ibrahim
Student Companion thank you very much!

Thanks you so much
+najeh mchirgui you are welcome!
Hello excellent tutorial! I use Mac OS and have installed MPLAB X IDE v3.15. However, Proteus is not supported on Mac OS. Which spice tool can I use? I would prefer that it be exactly similar to what you are using (plus has models of Microchip's PIC).
+Srujan Sriram We are not using Mac OS so it's gonna be difficult to suggest a spice tool for Mac Users, I would suggest to inquire from Microchip, they are in better position to respond to this query. Thanks
+StudentCompanionSA Thank you for your response. Questions:
1. How do I get the Proteus professional along with the PIC model?
2. I am seeing here that these tools are industry grade and hence, expensive (www.labcenter.com/products/vsm/picbundle.cfm). Is that correct?Are there any student grade tools with PIC models?
3. It seems cheaper to just buy a PIC development board. Any recommendations?
1. You can get a quote online and specify what tools and models to use, or contact them directly if you want a student discount.
2. There is a discount for student, you can contact them directly: www.labcenter.com/ordering/eprices.cfm
3. There are many boards on the market depending on what you want to learn. My favorites: EasyPIC v7 from Mikroelekronika,it's supports more than 387 PIC models with many peripheral supports, it's also on special (15% off) for these 2 days. You can use it with Mikroelektronika compilers (mikroC, mikroBasic...) but also with MPLAB compilers products by loadinding directly the hex code: www.mikroe.com/easypic/
It is the board we used in this tutorial: th-cam.com/video/c976a4Fmrps/w-d-xo.html
Microchip also have very nice tools, the low cost Curiosity Development Board is also on special :www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=DM164137
and the more comprehensive development board, the Explorer 8: www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=DM160228
Why does the LVP mode need to be disabled ? I noticed that my debugger demands it (Pickit 3).
agnichatian LVP is another form of programming a PIC using low voltage but this one is very tricky, if any condition is not met, the processor will reset. That is why it is always advisable to disable it unless you gonna program your PIC in LPV mode. I don't see why Pick 3 will request it!
I am new please tell me what is the name of the software for simulate Hex file ???..Thank you
+Umar Hayat That software is called Proteus. It's from Labcenter Electronics.
when i write the code , unresolved directives comes under #include and #include with a red underline. any suggstiions ?
Which PIC are you using? The versions of MPLAB X IDE and XC8 Compiler?
Do you need those directives? Chances are you don't need them so you can just delete them. Only use what you need. Even if they were included by default in this tutorial they are not used.
thanks for reply sir, i typed word by word from your video,but as mentioned #include and #include with a red underline, when buit up process, also when run this pgm,this error comment appears
make[1]: *** No rule to make target '.build-conf'. Stop.
make: *** [.build-impl] Error 2 ---this comment appears, also
Thank you so much for your videos sir.Please i just installed mplab x ide v4.05 and xc8 v2.10 and when i create c header file it keeps showing the error "cannot find include . And #include and every other header file highlighted in red. I have tried to uninstalled and reinstalled yet the problem is still there.Please sir how do i resolve this?
Hi. Did you try to write a short program and build it and see if it will not build successful without generating any errors? Don't worry if MPLAB X ID shows those red squiggly lines, it does not always mean it's an error, you can just ignore them, sometimes they will just go away. They won't prevent you from compiling successful your code. It's a long know problem and Microchip knows about it because many people in microchip forum have reported it but so far nothing has been done about it.
Sometimes reparsing your project can resolve them (right click and select reparse).
But if when you click on build if it fails to compile then post your code here and the full error message and we will assist you further.
hi! thanks for the videos, i only have a question, in the main program, when i write the line OSCCON = 0x76 meaning an 8Mhz internal clock source and i run the simulation in proteus the display keeps clear, but when i delete this line the lcd shows what it got to show, so whats the problem? can u help me please?
Hi hernán cote , did you set your configuration bits correctly?
It's a bit strange and it's a bit difficult to know exactly what could be the problem unless we see your code.
Can you send us your codes so we can have a look.
Send on facebook.com/StudentCompanion
Great video series! Quick question though: why do we define the internal oscillator frequency to be 8 Mhz? How do we know to choose that value? Can the internal oscillator generate other frequencies or can it only generate certain frequencies? Where in the datasheet would I check to get this information (for reference, the PIC microcontroller I'm using is PIC16F18446, but I think these questions are general enough that they apply to any PIC microcontrollers).
Hi. Thanks for the feedback. You can use differents internal oscillator frequencies, we just prefer this 8MHz for our tutorials. But you can't just pick-up any internal frequency, each PIC has a set of fixed internal oscillator frequencies you can choose from unlike if you select to use an external oscillator which will give you a wide choice. This information about internal oscillator options is PIC dependant, some have a many oscillator selection options, others just a few and some don't even have an internal oscillator or have but not very accurate like old PIC models, the PIC you are using is quite modern with possibly a wide choice of accurate internal oscillator frequencies.
The frequency selection is usually project dependant, some peripherals require high frequencies while others dont.
In general, higher frequency consume more power especially if your project is battery powered compared to projects run at lower frequency, so don't unnecessarily run your project at very high frequency if not required.
@@StudentCompanion Hello, thank you for your response :) I am glad that I found this channel because you provide great lessons, and you respond to comments. It is rare to find such channels!
I have another question. I am using MPLAB X IDE v5.40 and learning how to use configuration bits and since this video uses an older version of MPLAB X, things are slightly different. Now, if you feel that the following questions are better answered using other resources, I would highly appreciate if you could guide me to them.
Consider the following:
1) In this link, you will find a screenshot of the configuration bits window for the clock selection: imgur.com/a/q10yfIY
2) In this link, you will find a screenshot of the relevant section of the datasheet for the PIC16F18446:
imgur.com/a/05G15S6
In the first link, you can see that I have turned off the external oscillator mode (since I want to use the internal oscillator) and I have selected HFINT32 as the internal oscillator. Under the "settings" tab, the description states that the OSCFREQ = 32 MHz. Am I correct in assuming that OSCFREQ is the same thing as FOSC? I.e. both refer to the oscillation frequency of the selected oscillator?
Now, in the second link, you can see that the description says that I can select up to 32 MHz for this oscillator source. However, it seems to me that according to the first link, the oscillator's frequency is locked to 32 MHz. How would I select HFINT as the oscillator source, but make it so that its oscillation frequency is, say, 16 MHz? Would I use #define _XTAL_FRQ 16000000 ?
Thank you for your help.
Hi, I don't think you are selecting correctly the oscillator. You did not post the full configuration bits for me to see all your selection. Your PIC can select up to 32MHz internal oscillator but you didn't show the full configuration bits, I can't see how you selected the internal oscillator. We will read tye datasheet later to provide you with a definate answer.
The frequency is not selected in the configuration bits, you set it with the OSCCON register in your main program. Read the datasheet on the OSCCON register section.
For simpler clock selection, you can use MPLAB Code Configurator as explained in this video: th-cam.com/video/JxSSVtTj_fA/w-d-xo.html
For easy assistance, please ask the question on our Forum, there it's easier to post images or even MPLAB X Project so that we can see your configuration bits and the rest of the project.
Our Forum: www.studentcompanion.co.za/forums
@@StudentCompanion I have posted the question in your forum as well.
Great! We will have a look at it.
A question:
If in bit configuration the oscillator value has been already declared, why we need to configurate OSCCON register?
greetings
+Jesús Jiménez León in bit configuration you can only select either to use internal, XC, HS etc oscillator. If you opt to use internal then you can set the OSCCON register.
awesome, I think i'm working out all tutorials.
Thanks.
+Jesús Jiménez León Thank you. We appreciate your feedback.

I had built program according to the vedio in Mplab and while try to simulate in Proteus, there it showing "SCSx bits have been set. This feature is not modelled -". Can you help me to sort out this error
It's difficult to guess what could be the problem without more information . Did you use the same PIC as in this video? Did you build a new hex file or used our hex file? Is your schematic correct?
@@StudentCompanion problem solved . In edit properties I selected attach hierarchy module option. Then problem get solved . Thank you for your support

nwm. It works now. Somehow I didn't browse correctly for the .hex file? Strange, I can swear that I put the correct hex file.
Anyway, thanks and take care.
Good to hear you managed to fix it.
Sir, could you explain why it's not required to give power supply to the pic in the Proteus schematic
Hi. The pins for power are just hidden. You can right click the pic and show the hidden pins you will see the power pins.
It's not important, that's how they modelled the simulation component of the PIC, you are not simulating the pic power but the code, it's already assumed it's powered whether by 5v or 3.3v it doesn't matter
@@StudentCompanion Thank you very much for the prompt reply sir.
You are welcome!
14:21 Code not working. Can you paste working somethere code? Also if i name my source file the same as header file error occurs saying the name already exist.
What do you mean code is not working I must paste something working? You can see by your own eyes that the code is working by that simulation. They must be something wrong you are doing on your part.
Is your code compiling? What errors are you getting?
If the source file and header files have different file extension as they should, one .H and the other .C there is no way it can give you an error of same file already exist.
You can download this tutorial source codes from our website.
I see it is working for you not for me. Maybe some typo error in my case. I'm asking kindly if you can paste your code somethere, where i could copy and try it for myself.

hi sir
if i want to learn mplab ,should i learn c language at first? i have only basic knolodge in c language. which is the better way to learn mplab?
+Jayesh kumar p r you can learn both at the same time. MPLAB XC8 is ansi compliant, it uses C syntax. If you have basics knowledge of C that's great if not continue to learn together with XC8 as this compiler has it's own syntaxes as well especially how to access PORTS.
+Jayesh kumar p r Check the MPLAB Code Configurator, it generated easy to understand codes for your peripherals. It will make your learning easy:

thank you very much. i will try and let u know feed back
+Jayesh kumar p r you are welcome!
when i create a new source file #include is made by default should i leave it or delete it i am kinda confused or move to header file?
Leave it. If you delete it, your code won't compile. It include the PIC hardware details
@@StudentCompanion what about the other declaration such as stdio and stdlib
Those are standard C libraries. They are needed in some applications like when using standard C Printf() ect. But for simple projects like blink Led you don't need them. You can google them to het more information about them then you'll know when to include them.
Thank you for a good video
I am having problems with the 1 second delay line as the 'Error undefined identifier' keeps appearing. any ideas of what i have done wrong ?
Chris
Chris Perkins Did you define your oscillator frequency? normally before you use this delay function, you must define your oscillator frequency first using the: #define _XTAL_FREQ xxxxxxxxx (with the xxx your frequency. if you intend you use 8MHz, then it you can define as: _XTAL_FREQ 8000000 ). In this tutorial, we defined the frequency in the XC8.h file.
I have found the problem , I had missed one of the 'Curly Braces' from the end of the program. Thanks for the help. Just trying it on Proteus and then to convert the project to run on an 18F4550. I will let you know how I get on.
Okay good luck. Let us know if you manage with the PIC18F4550
+StudentCompanionSA I also worked on the same PIC18F4550 and I want to Know if the syntaxe is the same with other pic
I also want your chanal plz to subscribe because I serch tutorial No. 20 and i don't foun it thks
+Lila Ayad The syntax is the same, the only difference is the configuration bits, you have to set according to this PIC
can you show how to configure header file in ds pic33fj256gp710, i have tried to configure, but i didnt see mclr option and the options are different from 18 f
+Jayesh kumar p r Hi. At the moment we are working with only 8-bit microcontrollers.
Hi sir, thanks for your introduction. Can I ask what is the simulate program you are using in the video?
Hi. Thanks for watching our videos and for your feedback. The simulating software is Proteus.
@@StudentCompanion I was wondering if the free version of Proteus can run the simulation? do you think it's possible?
The free version doesn't allow you to save your work and it only runs simulation of provided examples. That's how it used to be. I don't know now. You can try it yourself
thanks for your kindly reply.
You are welcome!
Hi,
how can i get Proteus, cracked version.
+Khairul Alam Sojib we don't advocate cracking software. You must buy a genuine license from Labcenter Electronics (www.labcenter.com)
Why do you loop over __delay_ms(50) 20 times instead of simply calling __delay_ms(1000) ?
+Grant Smith in the older version of xc8 compiler it was giving errors when you use a longer delay. To overcome that was to loop several times a shorter delay. But this has been resolved in the current version of XC8. Now you can simply call __delay_ms(1000). It will work without problems.
Please do you know the subscription cost of microchip xc8 for
XC8 is for free but with only some code optimisation. If you need the professional license, you can either buy the license or pay a monthly subscription which is around $30 per month if my memory is still correct. But you can get the correct price from MichrochipDirect.
Hello Studencompanion, i´m so happy because i have found you. Your Tutorial is the best. So please can you help me? i have to Programme (whit MPLAB) a srf06 Ultraschallsensor with the PIC32MZ1024ECG100 and i don´t have any idea how i can beginn. the srf06 ist connect through a 4-20mA current Loop. Please can you give some idea? thank in advance!
+hosanalove According to it's description, you just need some resistors to convert the output current into voltage. You can use the analog to digital converter module of the microcontroller and display it. Check our analog to digital tutorial.

Hello sir, I loved your videos and I am constantly watching it. But sir I have a problem with my project and I need to contact you. Can you give any contact information?
Hi. Thanks for your feedback. You can ask your questions here on TH-cam or in the Forum on our website (www.studentcompanion.co.za/forums). Please note we don't provide tutorial support in private messages.
I've done everything in the video and the simulation works, however when I try the same in real life it doesn't work. The led blinks, but it's really fast. Changing the delay doesn't effect it. I did however disconnect it from power and placed the pic into a breadboard and powered it (5V to vcc and gnd to vss)...and connected the led. I did nothing else so I might be missing something. I'm using a PIC18F4520 for which the simulation works. Any advice?
If the delay is not working correctly it might be oscillator frequency issue.
Are you using internal or external oscillator? If external, the crystal oscillator value is it correctly configured in code?
If using internal oscillator, did you configure it correctly and configured the OSCCON register correctly with what value?
I did everything exactly like in the video. The only difference is the pic version. I'm using the internal one. From what I can tell, the OSCCON should be set to 0x76 with my pic too. ww1.microchip.com/downloads/en/devicedoc/39631e.pdf ...page 32
I defined the frequency the same way as shown in the video. #define _XTAL_FREQ 8000000
I've also noticed that when running the simulation, it runs, but gives an error. "[PIC18] PC=0x7FBA. The SCSx bits have been set. This feature is not modelled - the model continues to clock itself as before." Not sure if that matters though.
Since I did disconnect the pic from the programmer and later powered it with gnd and vcc, could that be effecting the program somehow? Maybe I should change something in the configuration bits part.
That's very strange, it should work, the OSCCON of 0x76 should also work well with your PIC. Please upload your MPLAB and Proteus projects in the Forum. We will have a look: www.studentcompanion.co.za/forums/
Will do. Thanks for the help.
Edit: here's a link for anyone with the same problem...if we manage to fix it anyway...www.studentcompanion.co.za/forums/topic/led-blinking-problem/

Hello everyone I have a question about pic programming times that how many times does pic microcontroller programmable and how can I find that my microcontroller now programme again X Times.And about PIC18F46K22 that how many times does it programme.
+PART&Co., by chipTALHAelectro hi. You can program a PIC microcontroller more than 100 000 times. With newer PIC Microcontrollers even very higher than this number. Read your PIC Microcontroller datasheet to get the exact number of times as it might be different from PIC to PIC.
I don't think there is a way to find out how many times you have already programmed your PIC.
Maybe you can inquire from Microchip directly. They might have some special tools for that. But this is my guess.
Thanks!!! Sir please also upload a video about how can I upgrade the new PICKit3 Original Programmer Firmware latest version using mplab x ide.
+PART&Co., by chipTALHAelectro thanks.
Hi :)
if you want to use the internal oscillator in addition to register Osccon you do not even have to set the register Config1h as the datasheet says ? Thanks
If you want , we can talk trought email :)
+Lorenzo Ruscitti you must always follow what the datasheet says. We don't understand your question
+Lorenzo Ruscitti talk about what through email?
Student Companion I have read the datasheet of your Pic , image on page 27, the block control clock has in input some bits of Osccon register and some bits of Config1h register.
Why do not you set the bits of Config1h ? Thanks
config1h was set in the configuration bit. That's the first bit we configured when we created the header file
Why does it show me "Target Memory Views" not " PIC Memory Views" for Configuration Bits ?
Meaning you are looking at wrong place
@@StudentCompanion Brohter, I klicked on Windows and then I came down to the "Traget Memory Views" because it doesn't show me the "PIC Memory Views".
It shows me "T.M.V." instead of "PIC M. V.". LCD Program does not work with that configuration Bits that I made from your toturial, but this time the Program works for 7-segment_Display.
Thank you for your replay!
Which PIC are you using? What is the version of your XC8 compiler and MPLAB X IDE?
If the LCD doesn't work, do you get error messages when you compile the code?
im having trouble with using delay ms() function sir
How do I know the value of OSCCON for another controller? I have 18F4620, I opened data sheet but I am not which value to take, can you advise please
It will depend on your selected internal frequency. The OSCCON oscillator control is explained on page 30 of the datasheet. If you use 8MHz as in our example, you can use:
OSCCON =0x76 //this in binary is: 1110110. Your can check the datasheet to see the selected bits.
This is perfectly clear answer, thank you a lot it really help me.
You are welcome.
Thank you for your video. I dit same in your video but it failed. Can you help me, please?

I watched your video many times but i don't know where is errors in my code.
+Nhung Phamthi It's complaining about undefined identifier "_XTAL_FREQ ". Did you define this in your led.h file? You cannot use the delay functions without specifying the frequency. If you're gonna use 8MHz, then write: #define _XTAL_FREQ 8000000
excellent!! I have a problem with xc8'S instalation. On the installation directory when I clic next, shows this error "C:/programFiles(86)/Miicrochip/xc8/v1.35 does not contain a compiler installation...
Help me
+Jasson Rodriguez Have you installed MPLAB X IDE first? Which operating system are you using?
+StudentCompanionSA win7 sp2 , yes I have installed IDE, I solve the problem installing xc8 v1.33 but now I can't create new projects
+Jasson Rodriguez Why? What kind of errors are you getting if you start a new project?
+StudentCompanionSA the program remains in the window "standalone project", don´t work , no response!!
+Jasson Rodriguez can you post a screen shot to see what os going on. post it to our Facebook page or email.
