Re: [AVR-Chat] AT90S8535 -> ATmega8535

It's a dangerous game you play, not having the source. It might be worth it to re-engineer the project! For what it's worth, I've not seen that issue, but the potential for odd things happening looked so great to me that I re-wrote my code for the mega8535 rather than rely upon the compatability bit.

I've just been handed an old project for which the sourcecode is lost. The board uses an AT90S8535 processor and has been upgraded to a ATmega8535. The compatibility bit has been programmed and everything's ok except for one thing. ADC0-ADC2 are used and for some reason these are shifted one step. I've checked the datasheets and AVR086 document but can't find anything new/changed that would matter. I've just opened the disassembler and the code uses single conversions so the changing channel during free-running shouldn't matter..? Has anyone else had ADC trouble when changing AT80S8535 -> ATmega8535? Yahoo! Groups Links
