This library only manipulates the I/O pins, so I didn't include "config.h" files etc., since they shouldn't matter. Config file used in this video is the same as all of my other videos, you can get it from here: drive.google.com/drive/u/2/folders/1CIP7N4szf0-AqrUNIvPVLEe5mSTxsLH-

Thanks 👍

Glad you got it to work 👍

​@@Microesque Can you answer on one question please, for some reason my LCD blinking every ±2-3s, can't understand it is a text or backlight, blinking I mean the text becomes more darker for about 0.2s and get back to normal, I update only last line every 1s, but blinking happens every ±2-3s. Im using good power supply, added all "filter" capacitors.

​@@filipp7611 I couldn't quite understand the problem. Is it the text or the backlight blinking? Either way, something like that will be the result of a power supply issue. If your text is blinking or resetting, make sure to check if the LCD is actually receiving 5V. These LCDs have a very tight operating voltage range. Getting even close to 4.5V may cause it to reset. If you have relatively high power components in the same circuit, or if you have long/thin power lines, your supply rail might be sagging just long enough to reset your LCD, but not long enough to be picked up by your multimeter. If the backlight is blinking periodically every couple of seconds, and you're switching something in your circuit every couple of seconds as well, there's likely a short circuit in your setup shunting the power rail to ground. The backlight is just an LED, it's not connected to anything else on the LCD. Unless there was a short, it wouldn't just turn off like that.

Thanks 👍

PIC16 microcontrollers are very old and use a different architecture; you shouldn't use them even for learning purposes, unless you have to. You can check the comment from "@joshuvajohnvarghese2372" below, where I explained the issue further. Basically you can make it work by: 1 - Changing the LAT... definitions in the header file to their PORT... equivalent. 2 - Making sure the pins you're using are properly set to digital (use PCFG bits in ADCON1). 3 - Making sure to not use an open-drain only pin.

@@Microesque Thank you a lot for the quick answer, I just have 6 units of 16f877 and don't want to buy new ones until I use those, next time will buy something new.

No books, just "XC8 User's Guide" and general C knowledge.

There are many ways to detect zero crossings, you don't even really need a microcontroller depending on what you're trying to do. Without seeing your circuit I can't really help you.

That is supposed to be the next video on the list, but I haven't had the time to make videos for a while now😟

Thanks 👍

Thanks 👍 I want to, believe me, but it doesn't seem like it'll be possible for a while still...

That depends. Most of the time, efficiency won't change since you'll enter and leave the interrupt routines the same number of times. Power consumption would only reduce if you also utilized low-power modes along with interrupts. As an extra note: Jumping to the interrupt routine takes 3-4 instructions. Checking which interrupt routine has been fired also takes many instructions. If you're using two interrupt routines at the same time, that also adds a bunch of instructions since there's only one set of "shadow registers" for this microcontroller. So technically, depending on the application, interrupts may even reduce the efficiency.

Anything custom from Microchip in the IDE (NetBeans) seems to use hard-coded colors. There's an output tab in the miscellaneous options, but it only seems to work on native NetBeans windows. Windows for MCC or analyzers are still completely white too. Unfortunately, there's no official support for dark-mode, so this is all we get. You just have to bear with it, or accept getting flashbanged forever...

Thanks 👍

Thanks 👍I don't have any courses or anything like that. This is kind of like a hobby I do for fun.

You too my man 👍

PIC24 are 16-bit microcontrollers, so the process is a little different. This is why I try to tech how to read datasheets and manuals. Answers to questions like these will almost always be somewhere in the user's guide of the compiler. I've included a short and a long answer below. I recommend reading both, but it's up to you 👍 ------------------------------- *Short answer:* -> Define the "FCY" macro as the instruction frequency of your microcontroller, so for 10MHz: _"__#define__ FCY 10000000UL"_ -> Include the "libpic30.h" library in your code: _"__#include__ <libpic30.h>"_ -> Now you should be able to use the same "__delay_ms()" and "__delay_us()" functions. Be careful, you need to define "FCY" before including the library! ------------------------------- *Long answer:* -> If you open the XC16 user's guide ( ww1.microchip.com/downloads/en/DeviceDoc/50002071K.pdf ) and go to page 63, there is a section for "How Can I Implement a Delay in My Code?". There, it tells you that there are library functions, but you have to download it to use them. It also directs you to another manual dedicated to 16-bit libraries for XC16. -> If you open the 16-bit libraries document ( ww1.microchip.com/downloads/en/DeviceDoc/16-Bit-Language-Tools-Libraries-DS50001456K.pdf ) and read the introduction etc, it tells you that the XC16 comes with the libraries pre-installed already. You just have to explicitly include them in your code. -> Now you can just search the term "delay" in the page to see your options. After finding the function you're looking for, it tells you which library you have to include, the signature of the function, and also a general description. I recommend you glance over some of the functions, as there are a lot of convenient ones that may catch your eye 👍

It's very easy to find datasheets aside from the lesser-known brands, so I didn't bother. Just type the name of your chip + "datasheet", and it should be the first link 👍

Thanks 👍

Thanks 👍

Thanks 👍

No, thank YOU for watching 👍

Glad you found it useful 👍

Update: I have found the problem and now it worked correctly. It was due to the way I name my folder and directory (with space and special character).

@@weekendle5564 Glad you resolved your issue 👍

I already have a debugging tutorial series, which is mostly done. Aside from that, I plan on keeping this series to this particular microcontroller and programmer for now. Maybe in the future 👍

Unfortunately, not yet. That's supposed to be the next video on the list, but I haven't had the chance to work on it for a long time.

Thanks 👍

That's in the part-2 of this video. Link is in the description 👍

I was born during the dinosaur period....thought maybe it was not used anymore. (we counted using dinosaur bones)@@Microesque

Of course. I was just trying to keep it simple since most of them rarely matter 👍 There are a bunch of limiting factors, and which ever one is the most limiting will apply. Max instantaneous current, max continuous current, max port current, max device current, max temperature, max power dissipation etc... Also, these are absolute maximum values. Ideally, you should never get close to these.

Appreciate the compliment 👍

Thanks 👍

Thanks 👍

Thanks 👍

Glad it was helpful 👍

Yeah, PIC16 microcontrollers are ancient and don't have LAT bits; they use their PORT bits to change their outputs. Ideally, no one should use them in this day and age. If you have any questions you can just mail me btw, I usually check it every day 👍

I'm assuming it worked out then 👍 Normally, ordering of the bit-fields is implementation defined in C; XC8 compiler strictly states that it orders them by their definition order, I guess that's also how CCS compiler is too.

@@Microesque CCS has hidden bit definitions, that I was unable to find. It's part of so called built in code of compiler. One of reasons I've made my structures/unions was an exercise for working with unions and structures, emulating CMSIS and bare metal programming for the STM32 MCUs.

When the LAT bit is 1, the pin connects to positive rail; if the LAT bit is 0, the pin connects to ground, that's all LAT bit does. If the cathode (-) pin of your led is connected to the microcontroller and the resistor connected to the positive rail, the LED will turn on when the LAT bit is 0.

@@Microesque Thank you so much! Now, it makes sense!
