AIn anomaly

Searched around the forum but couldn't see any thing applicable.So, thought to try here.

I am helping out with a project and they have a wireless receiver putting out to two motors for a differential drive system. IE M1= Left, M2 = Right.

The measured analog voltage from the RX is below 5v but seems to drift above and shut down when put to full. I have a safety band enabled and don't want to take a chance and disable.
I've re-calibrated the joystick a few times but same result.

Question: is there a setting to alter this max? Is it possible that the receiver is actually going above 5v?

Any ideas appreciated.

It is possible you are drifting above 5V. You can monitor the actual voltage the AIn is reading from the "Run" tab of Roborun+. Monitor to see if this ever goes above what you have set as your Max.

Beyond this it is difficult to tell without seeing what is happening myself. If you continue to have issues please download and install TeamViewer ( www.teamviewer.com ) and then contact me at This email address is being protected from spambots. You need JavaScript enabled to view it.

Yes, that's where I see it go past the 5000 mark. But by my voltmeter we are only at around 4.7- 4.9.

I'm not at the unit(it's a few hours away from where I am). If I can get back to it I'll contact you.
Thanks!

Should also add that it's running in Absolute mode. Not sure if that matters or not.
