Explorer HAT Pro - Touch pads don't seem to be working


I recently bought an Explorer HAT Pro for my Raspberry Pi 3 Model 3B+. I first installed the Explorer HAT with the “curl https://get.pimoroni.com/explorerhat | bash” command. To make sure that the Explorer HAT is installed and works correctly, I ran the “test.py” program, that is located at “cd ~/Pimoroni/explorerhat/examples”.
But then I got the following error message:

Exception ignored in: <function Cap1xxx.del at 0x764f29b8>
Traceback (most recent call last):
File “/usr/local/lib/python3.9/dist-packages/cap1xxx.py”, line 530, in del

if not self.alert_pin == -1:

raise RuntimeError(“Touch is unavailable, check your pHAT/HAT and/or connections!”)
RuntimeError: Touch is unavailable, check your pHAT/HAT and/or connections!

So touch seems to unavailable. By trying commands such as “explorerhat.touch.is_pressed()”, I get the same error message as above.

I also tested the lights with commands like “explorerhat.light.on()” and they seem to working correctly.

Since I wasn’t able to find anything helpful regarding my problem, I was hoping if someone in this forum could help me.

Thanks in advance for any pointers and guided advises you may be able to provide.

Did you have anything connected and setup on the GPIO Header previous to this?
Try running
python3 -m pip install --upgrade explorerhat

No, I never connected anything on the GPIO Header before. The Explorer Hat Pro was my first.
I also tried running the command and get the following result:

Looking in indexes: Simple index, piwheels - Simple index

Requirement already satisfied: RPi.GPIO in /usr/lib/python3/dist-packages (from cap1xxx>=0.1.4->explorerhat) (0.7.0)

The command didn’t seem to help either, since I still get the the same error message as before.
I also tried connecting the Explorer Hat Pro to my Raspberry Pi Model 3B, to see if it works there, but sadly I get the same result.

I have the same issue here and can’t find a solution. Any ideas? The lights work but not the touch API.

Raspberry model 3B and new explorer hat pro.

Posting this as an issue here may help.

I’ll also ping Hel Gibbons, she works for Pimoroni.
@hel @gadgetoid

I don’t own one, not much more I can do.

Have you checked that I2C is enabled in sudo raspi-config (or via the graphical configuration utility?). It’s under ‘Interfacing Options’.

Thanks, did the trick! So now it’s working!
