Tracy,
 

I have reverted back to the earlier IrDA receive circuit.  Here is a capture of the bit stream from pressing an "a" key.

 

I do believe the keyboard sends more than one character string per key press.

 

The signal is not totally clean and it does not go to zero, but rather bottoms out at about 1.08 volts.

 

In your opinion, should this be sufficient for the MAX3100 to reliably decode the bits or do I need to rework the receive circuit to really get the pulses down to zero volts?

 

Thanks so much for your help.

 

Best regards,


Mike
