I know that Problem. this happens, wehn you don't programm the AVR's
SS pin as an output before initing the SPI-Interface. If SS is
programmed as input while SPI is on, it will automatically send the
SPI-Interface to slave mode when a high to low transition occurs. You
must set SS as output before configuring the SPI!
Thanks,
I set SS to an output AFTER I initialized the SPI!!!!!
Yes, I saw that in your code.....
Is it working now?
Best Regards,
Peter
