Baby Orangutan USART

Has anyone had any luck using the USART on the Baby O? I successfully made the light blink but I seem to be having problems using the USART… does the use of PD1 (which is also the TX pin for the USART) as a driver for the LED inhibit serial comms?

Thanks // Martin


I’m not sure what you mean about “the use of PD1”. If you want to use the UART, you won’t be able to also use the pin as a straight digital line. The LED being on the line shouldn’t affect the UART; If you have the UART set up correctly, you should see the LED on when you are idle, and the LED should flicker as you send data.
