We have a pair of IrDA and its encoder/decoder. After reading the datasheet, we still dont know how to interface IrDA with En/Decoder.
Here is our current connection:
When using BAUD rate 9600, we are not getting any readable data from UART on arduino. The buffer is alway full or 0. We don't know whether it's the en/decoder or IrDA transceiver that is causing the problem.
Is this the right way to interface? Any advice on how to go about debugging this?
