Hi Peter,
the checking of frame_to_send works fine!
Thanks

Two things altered in this version:
-- checking tx-fifo overflow
-- dummy message to enforce the last stuck frame

I did a bunch of testing the firmware on Friday and I cannot find any issue with the last
packet. I suspect its a driver bug of some kind (maybe a race, or read order, or duplicated
read problem)

it is interesting that rx_fifo counter 0 but the frame is still there. The next frame pushes it out.
I'm going to do that if the message is more than 1 frame, I'll send a short dummy message that I will drop.

Better yet
not a standard message but 0 long blank message (with only one short int 0 content). This is swallowed by a handler, the client doesn't even know about

My suspicion is that the driver does an extra read, perhaps of the RXcount register

The interface card is ready.
On the card, an xmega communicates with the 7i80. The previous loop test runs fine. As time permits, software development for the application comes.
