Hi,
I have a problem with Atmel application "Using a Personal Computer to Program the AT89C51/../2051"(D285-B-12/97)...
I have made hardware and this hardware read processor, signature, erase processor.
When, I'd like to program, I try with test sequence 20,20,20,...20,(whole area), and after programming inside of processor is sequence:
FF,FF,FF,FF,FF,20,20,20,20,20,...,20,FF,20,20,20,20,20...20,20,FF,20,20,20,20,..every 32 places periodicaly...What is wrong,
Cable is very short (3"),
I think with timing in software.
Which your suggest?
Thanks,
GORAN
