I'm having no success with Example1_Constant_Read for the Simultaneous RFID Reader. I first changed line 277 in the library implementation file from:
Code: Select all
return (writeData(bank, address, newID, newIDLength, timeOut));
to
Code: Select all
return (writeData(bank, address, (uint8_t*)newID, newIDLength, timeOut));
...because the compiler threw an error on the implicit cast. The example sketch hasn't been changed though.

When running the example, the sketch stops at line 28, when the setupNano() call returns false, printing "Module failed to respond. Please check wiring." I'm not using it as a shield, I've just bread-boarded pin 2 on the reader to pin 2 on an Uno and pin 3 to pin 3 on the Uno (I also tried the reverse). The switch on the reader is in SW_UART. The reader is being powered by a 5V wall-wart and does work over USB with the UniversalReaderAssistant program.

Can someone point out what is missing in my setup?
