Afterburner: GAL IC Programmer for Arduino by -= olin =-
http://molej.cz/index_aft.html
Based on ATFblast 3.1 by Bruce Abbott
http://www.bhabbott.net.nz/atfblast.html
Based on GALBLAST by Manfred Winterhoff
http://www.armory.com/%7Erstevew/Public/Pgmrs/GAL/_ClikMe1st.htm
Supports:
* National GAL16V8
* Lattice GAL16V8A, GAL16V8B, GAL16V8D
* Lattice GAL22V10B
* Atmel ATF16V8B, ATF22V10B, ATF22V10CQZ
Requires:
* Arduino UNO with Afterburner sketch uploaded.
* simple programming circuit.
Changelog:
* use 'git log'
This is the PC part that communicates with Arduino UNO by serial line.
To compile: gcc -g3 -O0 -o afterburner afterburner.c
* 2024-02-02 Fixed: Command 'B9' (Calibration Offset = 0,25V) doesn't work
Note: Also requires elimination of a bug in the PC program afterburner.ino
Added: Sending B4, if b /wo -co is executed
