Touchpad problem

[Mares]

Hi,

i got CurrentRanger R3. So far so good. But i have the problem that the double touch is not working really good (Auto Range,BIAS,LPF).
I have to try 10 or 20times to touch both pads if it goes into Auto-Mode for example.

Is there a setup problem? Can a sensitivity change in the software fix the problem? Wrong parts on the board assembled?
Single contact to the touch pads is no problem. Only the simultanious touch.

I hope for help.
Thanks

I test each individual unit myself, and go through all the combinations, I never saw anything like that or I would change the touch sensitivity in the firmware.
What happens if you just touch one of the pads, then put your finger on the other? Is there a delay before it switches mode? Or it just doesn't work? What if you slightly moist your fingers?

Mostly it doesn't work.

Take a look in the video.

Ok i see, is this the original firmware?

[Mares]

Yes it is the original Firmware. I got it on Friday from Welectron. I think its a new batch.

Any Idea?

[Felix]

Can you contact me over email and I will try to help replace the firmware.

davidEnds,
Which R3mk is it?
Can you connect just the CR to the USB, open a serial port and send 't', if you have latest firmware that should enable touchpad sensitivity debugging.

[davidEnds]

R3 Mk4. Ok Ill try it Thks

[davidEnds]

The LPF and BIAS works perfect when the USB is plugged. When I remove it, it doesn't work again

[davidEnds]

Sorry, it just got back to work by plugging it into the usb and unplugging it again. What would be the explanation? Thanks for your time Felix

[Felix]

Sorry I completely missed the updates.
What output do you get when you type 't' with USB plugged?

See this line for that option, or send '?' for the menu options:  https://github.com/LowPowerLab/CurrentRanger/blob/master/CurrentRanger_R3.ino#L320

[davidEnds]

The current ranger doesn't show me anything on the
serial monitor. But the touchpad works well again just by connecting it to the pc

[Felix]

You're probably opening the USB port too late.
However regardless of that, if you open the IDE's serial monitor and send a ? followed by ENTER, you should get the MENU shown up.
Ensure it is the CR serial port and not some other serial port.

Thanks Felix!
