Update #12 is out, and located here (http://usfirst.org/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2010_Assets/Team_Updates/Team%20Update%2012.pdf).

There's a minor tweak to the Jaguar rules in PWM configuration, and a note on BOM convention.

Out of curiosity, does anyone know why it was decided that limit switches directly to a Jaguar using PWM is not permissible? I don't really see what sort of trouble it can create.

The general philosophy seems to be that all motors/actuators must be under computer control, and that would not meet this requirement

Under CAN control, the limit switch state can be read by the cRio. Under PWM control, it cannot.

But the bizarre part is that it does not have to be read by the cRIO under CAN control.

I don't understand why a distinction is made on whether it can be read or not.
