Colin you had mentioned before, I cant seem to find it,
about changing the 8535 with the atmega8535 and had some troubles with something,
I have replaced mine as well and reprogrammed it, no problems.
could you tell me what the problem is I want to verify if I'm also having the same problems and just havent noticed yet.

Thanks,
Troy

Hi,

My problem was it doesn't work at all. First, I couldn't reprogram the Mega8535 with the AT90S1200 as it is loaded with code to program teh 90S8535. The AT90S8535 uses byte by byte programming, whereas the Mega8535 uses page by page programming.

Also for some reason the latest Studio 4.07 code didn't seem to run in the AtMega8535, only studio 3.56. So I hacked the .hex file from Studio 3.56 so that it was reported as the latest version...

For me it was either all or nothing, so if it works at all its likely working 100%!
