Hi: Im using the uno32 revc with mpide 0023 20130715, just found that the UR2X is not receiving no mather what I tried, this is a small "loopback" piece of code for testing only

void setup(){

  Serial1.begin(baudrate);
  Serial.begin(baudrate);
  
  Serial1.write("H");
  Serial.write("J");
}



void loop() {
  
  while(Serial1.available()){
    Serial1.write("-");
    Serial1.write(Serial1.read());
  }
  while(Serial.available()){
    Serial.write("/");
    Serial.write(Serial.read());
  }
  
}

Im testing this code with an external rs232 converter and everything is fine on Serial, on Serial1 it sends but never receives

also tested pin 39 as an output blinking a led and fine, also fine as an input so the pin is not burnt

any ideas?

tested with serial1 alone, still not working

void setup(){

  Serial1.begin(baudrate);
/*  Serial.begin(baudrate);*/

  Serial1.write("H");    //just to see if its alive
}



void loop() {
  
  while(Serial1.available()){ //wait for incoming
    Serial1.write("-");
    Serial1.write(Serial1.read());
  }
  
}

Does your version have the Serial1+ vector fix in it?

WORKS!!!

I have made many searches to find this fix for myself but clearly did not use the correct terms

Thanks!!!! :D
