Welcome to the Agon-notes wiki!

Everything in one page for now, until we figure out what we've got...

Agon generally

Ours were shipped with version 1.02 of the MOS and the VDP firmware. We upgraded to 1.03 (which also needs a new Basic, still 3.00 but *version returns 1.04)

VDP (ESP32) related

Official AGON QUARK Firmware: ESP32 VDP https://github.com/breakintoprogram/agon-vdp

https://github.com/S0urceror/AgonElectronHAL looks useful and interesting but uses VisualStudio which is an adventure in its own right. Nonetheless Dave got it built and installed. It has dependencies - an older pre-1.03 MOS.

A Standalone ZDI Debugger

A small Arduino Uno project from a few years ago that implements a text-based ZDI debugger. http://hsl.wz.cz/zdi.htm

Connects to the debug interface with 4 wires (GND, ZDA, ZCL, RST)

I've built this and uploaded to the Uno and it works with the Agon Light.

This is the command I used to program the .hex file into the Arduino.

avrdude -F -V -c arduino -p atmega328p -P /dev/ttyACM0 -b 115200 -U flash:w:ZDI.hex
