This is the Atmega1284 firmware for the AY3 Synthesizer.

THANKS!

A million thanks to RIO for fixing and opening the code!

Install platformio and python2. (Yes. I am so sorry :(.)

To compile the firmware and to generate the firmware update sysex, run:

make firmware.syx

Then put the device into bootloader mode by holding down the encoder button while turning it on, and send the sysex. Note that you need to wait about 200msec between each sysex.
