Missing main.h file

[cjkraz]

Can't compile due to missing "main.h" header in "SCAN2000.c".

Haven't tried compiling yet, but it looks to my eye that everything is included in the c file, hence not needing a head (.h) file. Probably you need to fix your makefile? Can you post your makefile you're trying to get working?

I'm using the Arduino IDE to compile this source right now. (I typically develop on TI Devices).

The updates are a major improvement. The issue I'm currently facing is around the USART4 definition:

This should be closed. I had the wrong board selected. Your updates did resolve a number of issues I originally had with the code base.

Really appreciate the update!
