We have a STK500 Board with the ATmega16 chip and a altera DE2 with the cyclone || EP2C35F672C6N chip.
we are struggling with the communication between the two, it looks like the sampling are a few bits shifted to the left.
we are using RS-232 communication between the boards and have a baud rate at 9600 on both boards. we have a clock frequency at 3,68MHz.
USCRA = 0x00;
USRB |= (1<<TXEN);
UBRRH = 0x00;
UBRRL = 0x17;
The RS232 block in ALTERA DE2 is 50MHz and we wait 1.5 bit time between the sampling.
Have somebody any advice?
