I have the following problem:
I have a mega128 which runs at 8mhz (internal clock). It is connected to another controller via USART. The problem is that at the second controller I cannot change the baudrate, it always uses 115200. So my question is:
The error AvrCal calculates is nearly 8%. Does this work? Is there another prescaler or something like this in order to "finetune" the usart baudrate?
