Talons flash red on enable

[DDSLoan96]

Today we were planning on having the robot running around but we have hit a bit of a snag. When we enable our robot all of our Talons flash Red which means there is a fault. The only thing we see in the Talon manual is that it could be either low input voltage(checked we get 12 volts at each), over temperature(Cold to the touch) or a shorted output transistor. What can I do to fix this

Are you sure its a fault? They also flash red for reverse, which may happen if they aren't calibrated and/or you are leaning on a control.

It just means that the Talons haven't been configured yet. Once you configure them you will see that they will go to a solid orange state on enable.

Here is the Talon user manual. It contains the fault codes, and how to calibrate the controllers.

Does this have to be done with no motors attached
?

It doesn't matter if the motors are attached. But the motors will spin when calibrating.

The motors don't usually spin for us when we are calibrating.

Tried calibrating them this morning but haven't had any success. I'm going to probably set them up on a testbench when we meet later today and see what we can do then.

When the robot is enabled, do the wheels have resistance like they are getting power? I'm wondering if the motors are being told to move at a very low speed. What is the code telling the motors to do?

Its not a code issue at the moment since the output is disabled on the talons because it is detecting some sort of fault. Our electrical/programming mentor is coming today to help me figure this out

The LED on the Talon flashes between red and orange when a fault is detected. If the LED is just flashing red like you said earlier, then the Talon is outputting reverse.

Talons won't accept any sort of calibration. Joysticks are working because they work on our old robot and when we hook up a jaguar it works. Any suggestions?

And now they are magically working. Not sure what we did but they work now
