4:30 how is the atmega8 being powered if it is not connected to any powersource?? how ever in thecircuit diagram it is connected to 5v and gnd of arduino
The atmega88 is the newer version of the meg8. It's a better chip having more interrupt lines, and it works up to 20mhz vs 16mhz for the '8'. The mega8 might be cheaper, especially in surplus. BTW you CAN use the USBISP to program the optiloader on the chip. I've done it! (Via the command line with avrdude)
The ATmega8 vs ATmegaXX8 table you've shown seems to show 2 SPI interfaces, for most of the chips listed, including the 328P. That's wrong, isn't it? The Uno has two sets of pins connected to SPI (the 6 pin ISP and some of the D pins), but they're just wired together, aren't they? I now realise how difficult it is to get a decent high resolution schematic of the Uno, as an image. I'd saved several, over the years, but they're mostly too blurry to actually read properly.
Great video! It was very useful. But I have a question: how did you chose a 10kohm pull up resistor for the reset pin? why that value? I'm trying to learn how to calculate the right size for pull up/down resistors for logic CMOS digital circuits
10k is pretty much the default value for pull-ups and pull-downs. There isn't any precise value or formula to follow, pretty much anything from around 4.7k to 22k, maybe higher, will do. 10k just tends to be a value in that range that most people have on hand most of the time, so it kind of feeds back on itself and everyone just uses them by default and keeps them handy whenever a pull-up is needed. Pretty much the idea is to be a large enough resistance to be easily overridden by a connection to the other rail while being small enough that there will be enough current to maintain the desired input level. In general unless a datasheet specifies a different value, just assume 10k will do.
Too big a resistor can lead to noise problems where the current is so small that the gate can be affected by power supply noise. Too low a value resistor can lead to latching, where something trying to pull the line high or low cannot overcome the current, because of device limitations. So this is very dependent on what is attached to a gate. in general, anything between 4K7 and 10K should suffice.
There's definitely a gap in the explanation of configuring the FTDI board to load the chip on the breadboard. I've tried uploading blink to the COM port of my FTDI programmer and I'm seeing "avrdude warning: attempt 1 of 10: not in sync". I have no idea what the loading baudrate is supposed to be?
This video is 4 years old, yet is more useful than anything around recently. Thanks man! Exactly what I was searching when hitting a brick wall with my atmega32u chip (this one in particular are the ones Leonardo boards uses)
Where does that atmega8 vs atmegaxx8 table come from? It would be nice to be able to read it properly, instead of just being shown glimpses of it, or being shown it all but at too low a resolution to read it.
I would like to see an AVR programming troubleshoot video. I have multiple chips that get DID 0x000000 for some reason, preventing from programming them. I simply can't find the right solution
The chips maybe locked. Some cheap suppliers sell pre-burned chips. A high voltage programmer may allow you to reset the fusebits. They could alse be fakes. See the video on my channel for more about that...
I bought Atmega8 16pu and I have a question? Can I use another arduino Uno and put this chip in instead of 328 and to burn bootloader that way, using 2 arduino uno's?
Very informative video Just a question. Do I have to always use a FTDI chip based programmer to program the ic or can I just replace the ic present on my uno permanently.
I do as you describe and its work but I observe very important thing the "startup delay THE INBUILT LED BLINK 3 TIMES IN A SECOND THEN OFF FOR TWO SECONDS " so total about 3~4 second startup delay and how to get rid of it ?
Very good channel with not enough subscriptions :) I watched your watch project and it was amazing, show more microcontrollers and describe them as for an electronoob like me, please :D
hello 👋 bro , i follow as you told ,all works good but program is not uploading with usb ttl (cp2102) black colour board , i don't know why usb ttl is not working to upload program to atmega 8 ,its uploading to atmega328p but atmega8 is not supporting... is there any other way to upload program to atmega8
I would like to see the Parallax Propeller (P8X32A-D40) a 32-bit 8-core microcontroller capable of running at 80MHz and generating It's own video output if needed
Can someone help ! The library doesn´t stay in my IDE ! Everytime I Install anoter library the old one is gone ! Why is that ? How can I make them stay ???
dear ... i keep getting this error: avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xa0 !!
If I change the ATMEGA8's bootloader, will it work with ATMEGA8 only codes? I'm making a battery capacity tester designed by Danyk666 (DiodeGoneWild), and it needs a ATMEGA8 microcontroller And can you reprogram a ATMEGA328P to work like the ATMEGA8? Please reply fast
Nice Video But litte "fun fact" you could allready use an atmega8 whit the basic board libarry. Under the "arduino NG" bord you coud choose between a atmega8 oder atmega168. So theoretical you dont have to add new boards to your libarry but still nice to have.
Thank you so much for this video. I tried this at my home but didn't worked. I have uploaded "OptiLoader" code. But while uploading the Blink code it was giving me below error. "Access is denied. exit status 1 Error compiling for board ATmega8. " I tried with same settings as you shown. Please help me with this issue.
hello brother, can you make standalone programmer for arduino without PC. maybe the arduino using SDcard and just like click the push button and flash the atmega
Sir, if I use atmega8a instead of 8, process will be same or not? And pls make a video on difference between 8 and 8a. Pls sir. I didn't got 8 in market, so took 8a. So, I dunno the procedure is same or not, that's why I can't use it, in fear of it may burn.
Atmega16? Stepping back. I do recommend to get Atmega168 for projects that don’t need more than 16K of flash and Atmega32A that is more chipper than Atmega328. Try to use STM8S instead Atmega8. You will love it.
Then you may find the ATtiny13A interesting to. Less memory but much cheaper. Equally interesting is the ATtiny44A. Half the price (and memory) of the ATtiny85, but as many pins as the 84.
Want to help my workshop: www.patreon.com/ELECTRONOOBS
Thank you so much!
Yo. You should make a tutorial on how to design a bootloader in the form of an Arduino Shield...
I have one guestion. How about 328P in smd version is it same connections as in your tutoril arduino bare minimum or there is diference.
So far I have bricked 2 of my 10 atmega 8's ..... 8 more to go. Then I can recycle them.
Sir, send your mail id.
Starting program mode failed result
Sir whats is this problem
4:30
how is the atmega8 being powered if it is not connected to any powersource?? how ever in thecircuit diagram it is connected to 5v and gnd of arduino
Oh you are definitely staying awesome!
I cant wait for all of these lessons about the different types of micro controllers you have :D
Awesome video ! For a moment I thought you had forgotten the banana. Quite a relief to see it showing up at 4:30.
arduino ide always stuck at uploading while uploading blink to my atmega8
Ha merecido la pena escucharte. Gracias
pls help.. what to do if i dont have dtr pin?

@@michaelward402 lol I had forgotten this comment from 3 years ago. But thank you. It's useful information
Thanks! This also works same with uploading to ATmega328?
Sir, please Make a video on pic microcontroller
You just glided over that "if you get an error...." I am always getting an error, no matter how many times I press the reset button or type G.
There's definitely a gap in the explanation of configuring the FTDI board to load the chip on the breadboard. I've tried uploading blink to the COM port of my FTDI programmer and I'm seeing "avrdude warning: attempt 1 of 10: not in sync".
I have no idea what the loading baudrate is supposed to be?
Buen video, sigue así, siempre está interesante ver cosas nuevas
(good video, cotinue that way, always is interesting see new things)
This channel deserves subs.
Why do you need to connect all those components to the microcontroller between programming it with Arduino?
first attempt and immediately works, thanks
This video is 4 years old, yet is more useful than anything around recently. Thanks man! Exactly what I was searching when hitting a brick wall with my atmega32u chip (this one in particular are the ones Leonardo boards uses)
How did you make that banana IC😁
Where does that atmega8 vs atmegaxx8 table come from? It would be nice to be able to read it properly, instead of just being shown glimpses of it, or being shown it all but at too low a resolution to read it.
please make a video example of a simple tft lcd program using an atmega 16 chip.
Can't wait for PIC microcontrollers.
thank bro.
ESP8266 next tutorial please.
we appreciate your hard work and we are supporting you... *LOVE*
Thanks, Sir. for sharing your knowledge
can the same procedure apply for ATMega16 bootloader burn?
Gracias por el tutorial. Cómo configurar el oscilador interno de 8MHz del Atmega8?
I would like to see an AVR programming troubleshoot video. I have multiple chips that get DID 0x000000 for some reason, preventing from programming them. I simply can't find the right solution
The chips maybe locked. Some cheap suppliers sell pre-burned chips. A high voltage programmer may allow you to reset the fusebits. They could alse be fakes. See the video on my channel for more about that...
nice video thank you verey much.....but what is the board we have use it in opition when burning the bootloader
Thanks dude, this is work perfectly on atmega8
Is possible do this without the 16Mhz Xtal, using only 8MHz internal oscillator ?
Hi, does someone know at witch age you can make a Website?
is this can be applied for the SMD version (Atmega8 AU) too?
I bought Atmega8 16pu and I have a question? Can I use another arduino Uno and put this chip in instead of 328 and to burn bootloader that way, using 2 arduino uno's?
Very informative video
Just a question. Do I have to always use a FTDI chip based programmer to program the ic or can I just replace the ic present on my uno permanently.
how can burn the bootloader for internal 8MHZ crystal through arduino ?
I do as you describe and its work but I observe very important thing the "startup delay THE INBUILT LED BLINK 3 TIMES IN A SECOND THEN OFF FOR TWO SECONDS " so total about 3~4 second startup delay and how to get rid of it ?
Loved that a lot. I would also like to use the Attiny and the Atmega32A..
Do you have pic microcontroller tutorial?
Can we use Arduino in place of usb to Serial converter
I use the Attiny85 a lot because of it's small size which I program from an Uno. Nice video.
Plz🙏🙏 can I use atmega8L Instead of atmega8
How to upload Hex file atmega8?
Can i burn atmeg328p by using the same code???
j'ai la même question que vous mais je pense qu'elle restera sans réponse.
Good tutorial. Can you make a video tutorial series about PIC microcontrollers? It would be awesome!
you are the best sir
I want to upload arduino code on atmega2560. Do I follow the same method?.. I tried it but it doesn't work.
Can I use Arduino as ISP method to program atmega8 ??🤔
Great video as always!
But can anyone explain the meaning of the banana? :)
Its used for scale.
Nice! Thank you!
Banana's are awesome fruits.
Simple.
Really fantastic work, dude! 😃
And it shouldn't be difficult to make special boards to burn the boot loader and to program it. 😊
What is const alias_t aliases[] in Atmega32
Of course the atmega16 and those pics would be interesting. I can't find any good tutorial about the PIC MCUs.
can we use same optiloader code for atmega328 ic
I was about yeet my chip across the room until your video saved it.
Indeed.. good job dude !!

have you ever use the awesome attiny85
pd: also v-usb for avr is really cool
A future video will be on attiny85!
Thanks for using pic microcontroller
hi actually I'm facing a problem while uploading the bootloader to atmega8, it's showing (Starting Program Mode - Failed, result = 0xFFFF
)like
If I change the ATMEGA8's bootloader, will it work with ATMEGA8 only codes?

can i use this bootloader,code in Atmega8A-pu
Woww awesome bro! I love this kind of videos. What about a similar tutorial with the attiny10?
Is compatible for Atmega16-A?
Thank you for sharing. Could you also do a video on stm32?
Nice Video
But litte "fun fact" you could allready use an atmega8 whit the basic board libarry.
Under the "arduino NG" bord you coud choose between a atmega8 oder atmega168. So theoretical you dont have to add new boards to your libarry but still nice to have.
Thanks. I've tried that and for some reason didn't work...
Hey friend I like to male my owm version of this can it be done
Thank you so much for sharing this video, really very informative to me , please keep the good work
Useful video
Bro i beg please please please make a video on how to burn proggram in atmega 32 and 16
Can you upload the Banana bootloader?.
Awesome! Can you do samd21 next?
This is not working for me at all. I try do this for several days.
Thank you so much for this video.
I tried this at my home but didn't worked.
I have uploaded "OptiLoader" code.
But while uploading the Blink code it was giving me below error.
"Access is denied.
exit status 1

AtTiny841 is also a really great microcontroller.
hey can you do the atmega 2560 ???
Robot can make these arduin?
I often use the Attiny 85 and 84 chips and would like to see some projects done with them. Because they are dirt cheap 😬
Then you may find the ATtiny13A interesting to. Less memory but much cheaper. Equally interesting is the ATtiny44A. Half the price (and memory) of the ATtiny85, but as many pins as the 84.
