I've just built the UART sample code for the 722ze Nucleo board and have a problem. I have not modified the code (except for the transmitted character buffer). The sample code shows setting up the unit for a 9600 N81 format. The character buffer that is transmitted is 153 characters long. When I transmit from the Nucleo I receive the correct number of characters on the RealTerm serial capture program but it's gibberish. None of the ASCII characters are discernable and I can't make heads or tails of how the bits might be shifted... For example, I am sending "12345" which in hex is 0x31 0x32 0x33 0x34 0x35 and I receive 0xEB 0x9B 0x99 0x97 0x95.
Has anyone seen anything like this?
