Re: How do you set up the Talon SRX in position mode using the CTR absolute encoder

Yes I have. I have looked at most of the software manual. I did pick up an example at Git Hub that shows code that reads the least significant 12 bits, sets that as the initial position and uses...

Re: Talon SRX QuadEncoder PID Loop

Ah, we had the encoder's output inverted and not the sensor position's.
Inverting the sensor position fixed our problem, both the PID and soft limits work now.

Thank you for the help.
