/* Software serial multiple serial test Receives from the hardware serial, sends to software serial. Receives from software serial, sends to hardware serial. The circuit: * RX is digital pin 2 (P0_10) (connect to TX of other device) * TX is digital pin 6 (P0_2) (connect to RX of other device) Note: Not all pins on the Elbear Ace-Uno/Ace-Nano support interrupts, so only the following can be used for RX: 2, 3, 4, 5, 8, 9 Elsomik board pins with interrupts: P0_8, P1_4, P1_5, P1_6, P1_9, P1_10, P1_15, P2_7 Start board pins with interrupts: P0_10, P0_12, P0_13, P0_14, P0_15, P1_9, P1_15 created back in the mists of time modified 25 May 2012 by Tom Igoe based on Mikal Hart's example This example code is in the public domain. */ #include int rx_pin = 2; // P1_9 for Start/Elsomik int tx_pin = 6; // P0_2 for Start/Elsomik SoftwareSerial mySerial(rx_pin, tx_pin); void setup() { // Open serial communications and wait for port to open: Serial.begin(115200); while (!Serial) ; // wait for serial port to connect.
