George,
The BASIC program for ECU6/7 is compiled by Blue Earth Micro's BEC-51
compiler and delivers excellent speed in that form. It is also very easy
to imbed assembly in that particular compiler. Your help would be great.
If you have experience with flash memory, I have just the project for you.
We need someone who can adapt our flash loader from the old 12v chip to the
new 5v chip, as well as get the bugs out of it (the old program didn't work
reliably in any case). Let me know if this is something you'd be
interested in. Thanks.
Al
