Odd PWM problem (Can't get full green)
We are having an odd problem that we have been troubleshooting for the past two days.
We can't seem to get any of our Jaguars to output a full forward voltage. They output full negative just fine when we program them to -1 but an output of 1 is about half a volt short of the battery voltage. The jaguars aren't showing a full green LED. We have calibrated them and it's still not working. Things we have checked - Ran a basic program that only did PWM outputs directly - Changed PWM ports on the Sidecar - Changed PWM Cables - Changed Digital Sidecar - Changed Digital Module - Calibrated Jaguars We don't have any Victors to test with. I need to remember to keep one around for times like this. We also tested with a VEX cortex but its full forward nor reverse signals were giving full battery voltage or getting the lights to stay on. Any suggestions on what could be the problem? We are going to bring in an oscope tomorrow but we're trying to get the problem fixed today. Last edited by AllenGregoryIV : 23-07-2012 at 19:41. |
