I feel like an idiot, but I need help with ATMEGA162 USART0.
I am moving working M16 code to the M162. USART code works on 16, same
code (with register names updated to add '0' in them) does not work on 162.
I am using 14.7456MHz crystal on both designs, and set the fuses
correctly for that speed. I AM getting data on the TXD line, but it's
not correct, just jibberish. If I set the M161C fuse to 0, the USAR
stops working altogether (I assume due to the switch from using UBBRH
and L to one word).
Has anyone else made a move from the 16 to the 162 and overcome a
problem like this?
I'm gonna go check fuses again, but I've already checked them twice.
Jim
