Hello All, I have two of these transceiver. I had them hooked up to 2 basic stamps and they worked very well. Recently I bought an arduino 1280. C++ is a new language for me. So far things have gone pretty smooth. But I cannot get these transceivers to work. They are pretty simple, +5v, gnd and a serial input. I am connecting the trx pin of the 27997 to arduino trx pin 1 and using 2400 baud. Here are some snippets of code.
int rxPin = 0; int txPin = 1; pinMode(rxPin, INPUT); pinMode(txPin, OUTPUT);
Serial.begin(2400); Serial.print("A"); Serial.println();
I've spent most of the day trying different things but so far no success. I would welcome any suggestions.
