The 8.2 (or 8.3) Battery Voltage Bug

[eugenebrooks]

We are using a combination of Kevin Watson's camera code, using only the sensor reporting, not the servo functionality, and a timer/sensor interrupt to regulate the speed of our ball shooting wheel. We see the camera go off line sporadically, with some of the printf() statements ceasing to appear on the upload line. When this happens, the battery voltage shown on the OI is 8.2 (or 8.3) even though the voltage of the main battery is just fine.

We are backing out of the camera code, which depends on interrupts for the serial line support and our own interrupt based feedback for the ball wheel speed, but are interested in knowing if any other teams have seen this problem. It started off being very sporadic, but for some minor code adjustments can be something that hits almost 100% of the time.

We have integrated the new library code that fixes an interrupt problem
but this did not fix this bug for us.
