Re: Half Sidecar PWM Ports Working
 

Try making some code that allows you to directly control each output (As a Jaguar... like jag[1].Set(joystick.GetAxis(1)) ). See if the problem is really hardware or just your code not doing what you think it does.

Re: Half Sidecar PWM Ports Working
 

Yeah, we did this before we tried it with code for the mecanums, and it had the problems with the simple code.

Re: Half Sidecar PWM Ports Working
 

I will get one up shortly.

Just checked, all three power lights are green.

Here is our layout, without the motors connected.
We connect the black motor wire to the M- port, and the red motor wire to the M+ port.

I think you forgot the attachment. Correction it doesn't look like those pictures are public.

I noticed this when I posted it, but due to the securities on our school network, I couldn't easily fix them. Here they are now.

Re: Half Sidecar PWM Ports Working
 

I noticed you are using the ribbon cable. Could you have a backwards ribbon cable? I know those were floating around and its also easy to make backwards if you not careful. I am not sure of the symptoms of a backwards we have never had one backwards, but I know other teams have. Does anyone know if this could be the symptom they are seeing?

Re: Half Sidecar PWM Ports Working
 

This was the pre fabricated ribom cable from the kit, plus we tried it with another pre fabricated cable (an actual cable, not a ribon cable), so I don't think this is the problem, but all these cables were new this year so it is a possibility. I will check it tomorrow with the ribon cable we used last year and know works.
Thanks.

Re: Half Sidecar PWM Ports Working
 

So thanks for all the suggestion. Last Friday the sidecar started working again, and it was set up exactly as it was Wednesday and Thursday. This is good because the sidecar now works, but is also bad, because we don't know what went wrong. If you any other ideas as to what went wrong pleas let us know so that in the case it happens again we and other teams have a reference to go off of.

Thank you,
Team 4474

Bet the multipin connector was not fully seated at one or both ends.

Re: Half Sidecar PWM Ports Working
 

I was going to mention that driving your mecanums for a half hour might be just about the limit for a battery to handle. I know it is tempting to keep the testing going, but you really have to watch the power level during testing and driver training runs.

Re: Half Sidecar PWM Ports Working
 

Use some 4-40's to hold the ribbon cable into the sidecar and digital module. We've had this happen in the past to us.
