four-motor tank drive control

[BSV]

Hi all,

Our programmers are trying to set up tank drive controls and are having a hard time getting all 4 drive motors to fire simultaneously. They had it working for arcade drive, but when they switched to tank control only one of the motors on each side is firing.

We are using Talon SRXs on the CAN bus.

This document:

https://docs.google.com/document/d/1...VR0yS7cqI/edit

mentions how to fire all four motors using PWM output, but it is a couple of years old and doesn't talk about CAN.

Does anyone have a more recent example of how to make this work that I can point them towards?

Thanks!
