Re: [Emc-users] Faro Arm

[Chris R. <ch...@ti...>]

The short answer is you don't have a main function, which I suspect
was an earlier error, and you tried surrounding all the code in
faro_arm.c with main{ ... } which is not valid C.

The long answer:

You are missing a lot of code here, specifically the Serial_*
functions whose headers you have.

Your arm talks serial at 9600 8N1

It reports the position, button status, and error status whenever you
send it the two-byte string "_P".  It reports in a nice human-readable
ascii string that is 74 bytes long.

Doing serial I/O in C is kind of a pain.  I would recommend using
python (where you can use the hal python module directly) and the
python-serial module to do the I/O.
