Not no, but hell no Andrew. I saw my first micro cpu, an RCA 1802, in the spring of '80 when I was 46. And at 78 now, I still hack away at both gcode, hal files, and 68(3)09 assembly that runs on a TRS-80 Color Computer 3. You are a veritable spring chicken at 30. If you have the time to study, the "need to know how" is a very strong incentive. > > as for EtherCAT - read this first, its a license minefield: > > http://www.xenomai.org/pipermail/xenomai/2013-May/028597.html Scary.
