No I have no idea what's going on!

I have the same problem. It is solely related to the HD44780 driver.
(this is what my lcd is based on) It is in lcd_sem.c. This is semaphore
code to mediate access to the lp port.

I have no idea how a 'union' type/function works. Is this from C++?

Anyone with a bit more knowledge able to take a quick look at this and
point me in the right direction (or at least tell me about a union) and
I'll work the rest out?
