  The circuit:
  Two devices which communicate serially are needed.
- * First serial device's TX attached to digital pin 10(RX), RX to pin 11(TX)
- * Second serial device's TX attached to digital pin 8(RX), RX to pin 9(TX)
+ * First serial device's TX attached to PA0(RX), RX to pin PA1(TX)
+ * Second serial device's TX attached to PA4(RX), PA5(TX)
