Can't speak for the Talon SRX, but I just played around with error recovery for the PCM. I pulled PCM power towards the beginning of the flash, towards the middle of the flash, and towards the end of the flash. In all cases I was able to recover.

Sweet. That was one of my big concerns when flashing CAN Jags.

Re: blog; Motor Controller Options for 2015
Do the new talons communicate with CAN over the PWM cable? If so that's awesome.

Yes but its the other way around (I.e The new Talon SRX will run PWM over the CAN wires).

The new Talon will auto detect whether you are connect to a can bus or a pwm source.

On FRC you only need two wires for PWMs (signal and ground) to an FRC legal motor controller because all FRC motor controllors ignore the center power pin (these are only used for servos)

You can wire the 2 CAN wires on the Talon SRX to PWM signal and ground and it will auto detect PWM.

CAN_H = PWM Signal
CAN_L = PWM Ground

The Victor SP (which has a 3-pin PWM) can only be used in PWM mode, no CAN available

Hope this helps,
Kevin

Thanks, can you change PID values and configuration over CAN without a separate utility?
