Serial Port: Plain Text

Available on: Flexs Q5C Flexs Q5 Pro Flexs Q5M

Minimal RS-485 usage: initialise the port, print every carriage-return delimited message that arrives, and transmit a text line once per second.

let port = 1; // Available ports vary depending on the device. Refer to the serial.init documentation

function serialRxCallback(msg){
  print("Received Serial Msg");
  print("Port:", msg.port);      // port of incoming msg
  print("Overflowed:", msg.ovf); // msg.ovf is boolean true / false
  print("Data:", msg.data);
}

serial.init(port, 19200);
serial.listen(port, "\r", serialRxCallback); // buffer rx until a carriage return arrives

while(run()){
  serial.tx(port, "Hello World over serial!\r");
  waitMS(1000);
}
