This is a GAL IC programmer software that allows to program GAL IC chips from various manfucaturers. It is based on work of several other people:

Bruce Abbott: http://www.bhabbott.net.nz/atfblast.html

Manfred Winterhoff: http://www.armory.com/%7Erstevew/Public/Pgmrs/GAL/_ClikMe1st.htm

who did the most of the hard work of deciphering and publishing the programming protocol of these chips. Their programs were Windows based and relied on presence of parallel port (LPT). Afterburner was written for Linux OS (also works on Win32/64, Mac OSX64), and requires serial connection to Arduio UNO, which does the programming of the GAL chip.

Supported GAL chips:

Atmel ATF16V8B, ATF22V10B, ATF22V10CQZ

Lattice GAL16V8A, GAL16V8B, GAL16V8D

Lattice GAL22V10B

National GAL16V8

Please note that ATF16V8C or ATF16V8CZ are not currently supported. Yes the B/C at the end of the part designator seems like a minor thing but in fact the programming protocol seems to be different compared to the B version (which is supported). Keep it in mind when ordering parts.

Setup:

Upload the afterburner.ino sketch to your Arduino UNO.

Connect the pins of the GAL chip to Arduino UNO according to the schematics images. Ideally use a PCB (ether etched or made in a fab) that's provided in 'pcb' and 'gerbers' directory. You can also hardwire on protoboard or breadboard.

Compile the afteburner.c to get afterburner executable. Run ./compile.sh to do that.

Set the programming voltage (VPP) on the voltage up-converter module (MT3608) depending on the GAL chip

Atmel ATF16V8B: 10V

Lattice GAL16V8: 10V, also works with 12V

Others - between 10 - 14V - untested

Check the programming voltage (VPP) without the GAL chip being inserted / connected to Arduino UNO. Test the voltage on MT3608 module VOUT- and VOUT+ pins while running the following command:

./afterburner s

Check the chip identification by runnig the following command:

./afterburner i -t [GAL_type]

If you get some meaningfull GAL chip identification like:

PES info: Atmel ATF16V8B VPP=10.0 Timing: prog=10 erase=25

then all should be well and you can try to erase the chip and then programm it to contain your .jed file.

If you get an unknown chip identification like:

PES info: 3.3V Unknown GAL, try VPP=10..14 in 1V steps

then look at the troubleshooting section

Read the content fo your GAL chip. This only works if the contents of the chip is not protected. Use the following command:

./afterburner r -t [GAL_type]

or to save the printed .jed fuse map to a file use:

./afterburner r -t [GAL_type] > my_gal.jed

Erase the GAL chip. Before writing / programming the chip it must be erased - even if it is a brand new chip that has not been used before. Use the following command:

./afterburner e -t [GAL type]

Program and verify the GAL chip via the following command:

./afterburner wv -t [GAL type] -f my_new_gal.jed

How aferburner works:

PC code reads and parses .jad files, then produces a binary which can be then uploaded to Arduino via serial port. By default /dev/ttyUSB0 is used, but that can be changed to any other device by passing the following option to afterburner:

-d /my/serial/device

PC code of afterburner communicates with Arduino UNO's afterburner sketch by a trivial text based protocol. You can also connect directly to Arduino UNO via serial terminal of your choice and issue some basic commands manually.

Arduino UNO's afterburner sketch does 2 things:

parses commands and data sent from the PC afterburner code

toggles the GPIO pins and drives programming of the GAL content
