WebMar 15, 2016 · Update 2. I have isolated the problem to the setbaud.h file. If I set the baud rate 'by hand', that is, using the following code in place of the call to initUSART (); above, it works as expected - the BAUD is correctly set to 9600. This sets the prescaler to 12 (0b00001100) and enables USE_2X. WebMar 30, 2024 · The letter is being transformed into right amount of data, which can increase the amount of data being send into PC BUT the amount of data being transmited depends on baud rate.
