I did the same as well, but it runs pretty quick so I don't mind.

The problem I had with getting it to start talking right away was that the
IRQasn't being generated at initial startup to send a character.  After you
put a char into the software queue (to feed the ISR) you need to enable the
Transmit Empty IRQ bit from the character buffer-writer.  You only need to
do it if this is the first char in the buffer.  After that, the ISR handles
it OK.

This was a really slick chip to get working.  I like it!  It'll end up more
designs, for sure.  I used the basic framework for the ISR that I use for
the on-PIC UART.

Tomorrow morning I start on the ADC chip.  It should be pretty straightforward.
