[UART] Maixduino Reading Serial port

[NikolaiBirolini]

Hello everyone !

I want to read my UART's output of my barcode scanner and print it on my computer. My code :

char outBarcode;

void setup() { Serial.begin(115200);
Serial2.begin(115200, 6, 7); }

void loop() { Serial.println(Serial2.available()); if (Serial.available()) { Serial.println("Scanning") outBarcode = Serial2.read() delay(1000); Serial.println(out) } }

But my Serial2.available is always equal to 0 .... So, firstly, is this code seems correct ? And can I write others pins in Serial2.begin(baud, RX, TX) ? For example, RX = 10 and TX = 11 ?

I wish you all a good day ! Thanks for reading me !

Hi friend, i will help you as far as i know.First, make sure you have made the connections correctly.Because I had such a problem.

You probably got the connection on the board wrong.If not, I'll try to help.
