TrexJr control methods
Posted: Sat Jun 21, 2014 10:04 am
Hi.
I'm very new to this world of micro controllers, embedded communication protocols and programming. I'm going head first, in deep water (if that's a saying) and started with buying the pyb and some stuff from pololu.
One of the items is the TrexJr http://www.pololu.com/docs/0J5/all, this can from my understanding be controlled with either servo (pwm), analog, rs232 (-12v - 12v) and logic level serial(?).
Can I use the logic level serial on the pyb? been looking for some documentation regarding this on the pyb, but now I'm just taking turn round myself...
Edit: Its typical, right after I posted this I found out about UART https://www.sparkfun.com/tutorials/215 and as far as I can see, it's the way to go (I want to keep servo connections on pyb and Trex free for rc and servos later on)
Feel free to come with tips and confirmations, I'll really appreciate it.
