Serial.println('Now switching over to UNO for 20 sec. Tested - I am happy because, it works in the way I have made it to work. This is the hardware setup where, 2 SUART Ports are present each SUART Port remains open for communication only for 20 sec. I understand that it is one after another no two SUART instances could be made active at the same time. I have not tried, and now I am going to try. Tested with Arduino Uno and Mega, but should work on other boards/MCUs. With millis interrupt disabled, it works up to 250,000 bps. Works reliably up to 125,000 bps with millis interrupt enabled. In addition, it uses the input capture feature of timer 1 for improved accuracy. N = SUART.available() //checking if charcater has come from InputBox of Serial MonitorĬhar x = SUART.read() //yes, there is a charcater read it Software serial library using a single line in half-duplex mode.

SUART.print(x) //send the charcater to NANO as ASCII code Serial.print(x) //send back the charctaer to OutputBox of Serial Monitor SoftwareSerial SUART(10, 11) //SRX = 10, STX = 11īyte n = Serial.available() //checking if charcater has come from InputBox of Serial MonitorĬhar x = Serial.read() //yes, there is a charcater read it

STX Pin: Dpins: 2-13, 20-69 (not tested all the pins) Only the following pins can be used as STX pins for SUART Ports. Only the following DPins of MEGA could be used as SRX (RX pin for the SUART Port) Pins: Along with 4 hardware UART Ports of MEGA, it is possible to use many more software UART (SUART) Ports under the following conditions:ġ.
