Hi, I have a managed to get a Parallax RFID reader working with the Netduino and also have managed to get a serial shield working too. However I can only get them working separately using COM 1. Can someone please help me wire both bits onto the Netduino? How do I go about using COM1 and COM2 (i.e. which pins represent COM2). Thanks

Hi WahidM, This has been explained in http://www.netduino....uino/specs.htm: ● digital pins 0-1: UART 1 RX, TX ● digital pins 2-3: UART 2 RX, TX So for COM2, you should put the wire that's currently in pin 0, to pin 2, and pin 1 to pin 3.

Link is bad... http://www.netduino....duino/specs.htm Basically what you are looking for is this: digital pins 0-1: UART 1 RX, TX (COM 1) digital pins 2-3: UART 2 RX, TX (COM 2)
