newbie Dragon12 board softwar-hardware question

Hi Edward,
I want to use C and I don't have a BDM.

As you said, assembly seems is possibility. I'm trying to avoid going to assembly level because the data capture and processing will be labourious and probably unachievable in the about 7 days I have left to project completion.
The good news is that this week I finished the final exam for the embedded
-hopefully successfully
so I just have 2 projects: this adaptS12DP256 and the other course I'm taking. And of course my day job.

So the unavailability of a system that could be programmed in C might derail my chances of finalizing this course in time.

Cheers,
Adrian

Or you could call up the people at Tech Arts and order a BDM module for your processor board, or at least discuss with them what you need to do. They even have student bundles.

If you think it is too expensive, think of how expensive it would be to not finish the course.
