Re: Troubleshooting motor controllers
 

The only thing that i can think of is the Digital Sidecar not working properally. Is there a way that i could fix it.

Thanks MichaelBielecki. The RSL is always solid.
I will try this now.

EDIT
I tried this and still no change.

Next this.

EDIT
Still no change.

We use this to generate a pwm signal to a motor controller. Great device to have to test the motors without hooking up the electronics.

You say the RSL is always solid, even while disabled it does not blink?

I would try swapping Sidecars if you have a spare.

IMO that $50 would be better served towards an arduino with a potentiometer. This gives you a tool with endless possibilities (including acting as a motor controller). Actually, AndyMark now has a shield for an arduino that can make it replace your cRIO for testing, which makes an arduino all the more valuable.

Or spend $0 and make one with an old junker laptop.

This sounds AWESOME!!! Thanks for telling me!

We replaced the digital sidecar and now it works perfectly!

Thanks to everyone who gave suggestions!

Great to hear that.

Could you open up the bad DSC and have a look inside? I'm sure I'm not alone in wanting to understand why a DSC that appeared perfectly functional wasn't actually working.

Re: Troubleshooting motor controllers
 

I have done that, I could not see any physical damage to the DSC.

my team captain wants me to program our autonomous code to have it reverse and then spin 180 degrees. The only problem is that no matter what I put in as the motor values, the robot will either just reverse or it will start to do the harlem shake. Can anyone please take a look at it for me?:confused: C:\Users\Matt\Documents\autonomous c...r problems.htm

Wow, fantastic! We're always looking for cheap solutions using old "trash".

You might want to look at that URL you posted. It's going to be kind of hard for us to look at something sitting on your computer.... ;) And you might want to find a thread that's more closely aligned to your problem, or start a new one. More of the right people might see it.

I don't have one but I saw this and it looks kinda cool.
