WebAug 24, 2024 · Software UART is generated by the compiler with the same previous function. For example TX is mapped to pin RD0 and RX to pin RD1: #use rs232 (xmit = PIN_D0, rcv = PIN_D0, baud = 9600) where 9600 is the baud rate. The functions used in the C code are: printf: sends a string of characters over RS232 transmission pin (TX).

WebNov 7, 2016 · The EUSART module supports 9-bit asynchronous communication with the ninth data bit’s function (i.e., parity or address indicator) to be determined in software. The UART with protocol support, on the other hand, allows the use of the ninth bit either for parity checking or address detection in hardware. 8-bit Data with Even or Odd Parity WebIf I don't use interrupts (if I just poll the RX flag) then it works just fine. But I'm getting unexpected results when trying to use interrupts. For example, if I only enable the RXNE ("RX not empty") interrupt using USART_ITConfig(USARTx, USART_IT_RXNE), then the code should only vector to the ISR for this one specific event. But the ...
