hello world! is an unknown quantity at this point
Digital Sidecar not giving PWM signal to the speed controllers

The basic problem that i have is that when I deploy the code to the cRIO, the victor speed controllers (along with spike relays and pretty much anything else hooked up to the digital sidecar) keep giving me the flashing light, like they are waiting for a signal.

Some details about the digital side car is when the code is not deployed and everything is disconnected,(except for power of course) only the BAT light is on. When I plug the ribbon cable into the digital sidecar, the 5V light comes on. When I deploy the code the 5V light goes off unless the ribbon cable is at a weird angle, then the 5V light comes on and the victor speed controls work ... sometimes. Sometimes they still give me a blinking light and sometimes they get a mind of their own and go at whatever speed they deem necessary.

Things i have tried

1) Try going with the default code to see if that was the problem (It wasn't)
2) Tried unwiring the power and rewiring it
3) Tired rewiring the ribbon cable to see if it was wired backwards

Is the 6V light supposed to be on, and when is it supposed to be on?
What would be the problem?
Anything else i can try before deeming the sidecar broken?
