I want to use the UART on the STM8A-DISCOVERY boards.
However, AFAIK, the STM8A RX and TX pins are not connected to any header on the boards. There are open solder bridges connecting them to the ST-Link/v2 interface. I could just solder some wires to the STM8 side of these open solder bridges to get the RX/TX signals. Any better ideas? Philipp2016-01-11 07:11 AM
Since I only need to transmit data from the STM8A-DISCOVERY to the host, I used UART3 instead of UART1. The Tx pin of UART3 is pin 1 on the LIN jumper.

Similarly, on the STM8AL board, the Tx of UART1 is available on the LIN jumper, pin1.
