So I got this board a week ago and using it with an arduino works like a treat.
But I've had no luck connecting a UART/USB adapter to the Serial port of the device.
The Universal Reader Software does not recognize the reader.
No matter how I power the board - via the UART/USB adapter or via bench supply - seems like it does not want to talk through the Serial port. Even screen was not able to pick up anything from the reader... thought maybe it would talk a bit during boot... nothing... nada...
Am I assuming correct that the UART on the serial port of the reader is 3.3 V logic level?
Has anyone got this device to work with the version 3.3 Universal Reader Software? (the tutorial references version 3.2)
Any other test I should be running?
Finally got it working... turns out 3 of the 4 UART/USB adapters I got were rubbish...
No public wish lists :(
