Error initializing `Adafruit_STMPE610_SPI`

Hardware:

We are getting this error when we try to run the “simple test” code:

Traceback (most recent call last):

We tried:

Replacing GPIO wires
Using a new touch controller
Using a new touch overlay
Flipping connection to touch controller

Can you please help? :)

are you running as sudo? are you running the latest version of raspbian OS? did you update all pip packages?

FYI - I just tried the stmpe610_simpletest on an RPI 400 with CS on D21 and it worked as expected. I was using an STMPE610 breakout board with an attached touch screen.

I did not have to use sudo...

Thanks for the quick response!!

I am running sudo, I am running on Manjaro ARM release 21.01. All pip packages were freshly installed.

Pip packages: Adafruit-Blinka==6.4.2 adafruit-circuitpython-busdevice==5.0.6 adafruit-circuitpython-stmpe610==1.2.5 Adafruit-PlatformDetect==3.5.0 Adafruit-PureIO==1.1.8 pyftdi==0.52.9 pyserial==3.5 pyusb==1.1.1 rpi-ws281x==4.2.6 RPi.GPIO==0.7.0 sysv-ipc==1.1.0
