Could I bug you to code a fifo into your code?

 

The logic on the PC is simple:

 

sets pcack (rb.3) low

waits for byteready (rb.2) to go high

 

gets the byte, and stores it

 

sets pcack (rb.3) high

waits for byteready (rb.2) to go low

 

loops to the beginning

 

I'm sure you probably already guessed that based on the code you wrote, but just in case.

 

As I mentioned, my fifo code is already written, and I'm in the process now of debugging.  I think that code is solid but who knows?  I'm using a 16-byte circular buffer.

 

It's tough debugging code whenever you aren't even sure the other portions of the program works.  I guess thats what modular programming is for.

 

Thanks.
