Spent some time refining my minimal #Arduino design with #mosfets and a ZIF28 socket to allow it to be a general purpose #ATmega328P programmer. So far I am pleased, but the test build is next...

Done! My "Blank to Blink" minimal #Arduino project is finished. I put a blank #ATMega328P on a breadboard, got an #Uno bootloader into it and then download the #blink sketch, and it all worked! Yahoo!! 🥳

Yeah, I am pleased, hell yeah! 🍾

after 7 years I still find this very impressive, how much you can do (#ffft #fft) with such a limited MCU (#atmega328p) and a simple #arduino sketch

I am not sure what to do with this exactly but because Mastodon gives me enough space that I can go beyond just sharing a link to a new blog post, I want to make use of that.

The TL;DR is:

I wanted to learn how to program an #atmega328p using existing gear I had on hand rather than buying a programmer. It can be done with a #Tigard but I couldn't find all of the information I needed to do so in one convenient location, so this blog post is the information that I needed pulled together.

If you have a #woprsummit 0x01 badge and you're not sure how to program it, there might be some useful information in there for you. Maybe you can use it as a basis for figuring out how to do it with another device.

Maybe you've got a different #avr microcontroller but you're not sure how to program it.

The basic steps are:

Set correct target board in #Arduino IDE
Export compiled code from Arduino
Wire Tigard JTAG header to target board’s ISP header according to the diagrams
Select JTAG on Tigard mode switch
Select desired voltage on Tigard
Plug in Tigard via USB-C
Set fuses - avrdude -C +tigard.conf -c tigard -p atmega328p -U lfuse:w:0xFF:m -U hfuse:w:0xDA:m -U efuse:w:0x05:m -> Note different fuses may be needed depending on device config
Upload code - avrdude -C +tigard.conf -c tigard -p atmega328p -U flash:w:/path/to/firmware.ino.with_bootloader.standard.hex

There's also some bonus info in there about integrating the Tigard with Arduino IDE.

The Tigard was designed (at least in part) by @securelyfitz

I believe the WOPR Summit badge was designed by @dntlookbehindu and @kismetwireless .... at the very least they're the ones that were helping out on Discord with questions.

You can learn more about WOPR Summit here: https://www.woprsummit.org
