Delco 68HC11 debugger

Post by BennVenn »

20 years too late?

I've been working on this in the evenings, an '808 or similar debugger. Still a work in progress but I've got it disassembling in real time, executing code, updating RAM and registers. Branching, looping, all that good stuff.

Still have a hundred or so opcodes to support.

It's main use is to find where the main loops of code are, when certain registers or peripherals are modified and hopefully to make it easier to add RT support to anything that'll run on an HC11.

I plan to have readouts on the FMC registers and outputs (injector PW etc, dwell, spark angle) and inputs for RPM, MAP, TPS etc...

I'll release the source and it shouldn't be too hard for others to modify it to support banking or whatever is missing for their application.
