No-IDE Arduino Programming! Hex/Bin File upload from Command Line – AVR/ESP8266/ESP32

thanks

like the information, but dislike that its strechted to 10 minutes if you could have done it easily in under 2 minutes

Short and to the point thanks for posting

Cube led 16x16x16 ?

Why don't you just export it as a bin file and then flash it that way over and over by hitting flash by using a program like ESP easy or something like that

Kind of glasses over the bit about sending the precompiled file to someone else and why the target path needs to be changed, and that sort of thing. Good info, though.

If you needed to load many many boards, then you should write a shell script. On Mac and Linux, a bash shell script. The simplest one is:
while true; do <insert avrdude command here>; done
When you've done your last board, hit control-c a few time until you get here your command prompt back.

The only problem is synchronizing each call to avrdude with the act of disconnecting each complete board and reconnecting the next one. The simplest way to handle that is to have the script block for user input between each call to avrdude, like this:

while true; do <insert avrdude cmd>; read x; done

Now you have to press enter after you connect each new board to be programmed. That isn't a whole lot better than pressing up arrow and enter. So another idea is have the script beep and sleep a few seconds:

while true; do <avrdude cmd>; echo <control-v><control-g>; sleep 5; done

Where it says <control-v><control-g>, you hold control key and press v at the same time, release them both, then hold control key again and press g at the same time, then release both. When the script runs, this will make a beep. Now you have 5 seconds (or whatever number of seconds you want) to remove the competed board. I believe that as long as there is no board on the programmer, then avrdude will block until one is detected. If I am wrong about that, then this sleep method may not be suitable.

Check out the man page for avrdude, as it may have command line options to assist with automation and scripting.

On Windows, you could do an equivalent power shell script, I suppose. Powers hell is nice to have as an option, but I never look forward to using it.

Great stuff! I was glad to learn this. Will be looking forward to a video explaining more of what's going on in verbose output.

Hi Kevin. Very useful info. 2 questions: #1 what about the fuses to set the ATmega328 clock to 16Mhz? I think this is accomplished when using the "burn bootloader" command in the IDE. But what about "fresh" chips that are still set to factory defaults?
I am using the standalone programmer from Robert Patterson (based upon the Nick Gammon code), and this does burn the fuses to set the clock speed.
Question #2: From the video it looks like you are using a 6 pin Serial to USB FTDI (as opposed to ICSP port). Maybe I am doing something wrong, but when I tried to communicate with the 328 chip using the serial connection, it would not work until I executed the "burn bootloader" command using the ICSP port and a NANO configured as a programmer.
We have close to 1000 boards to program every year, and I am looking for the best solution for this process. Thanks for your help.

thanx itsi nteresting

Can't it be scripted then with board detection

Finally someone explained how to do it. However, it was too fast for me to keep up. Could you do an instructibles.com tutorial on it? Really appreciate your videos.

Platformio.
