Re: [FTC]: 0.0v on Ext Battery Problem
I assume from the post that the TETRIX DC motors and servos are operating as expected (they respond to commands). The only problem is that ROBOTC is reporting a zero voltage.

I am fairly certain that last year's ROBOTC firmware was only able to read the voltage of the external battery if a motor controller was the first device attached to NXT sensor port #1. ROBOTC will report zero voltage if a servo controller is the first device attached to sensor port #1 or if the controllers are attached to a port other than sensor port #1. I don't know if this applies to this year's firmware.
