New GFX Hat delivered last week. Tested on pi4b and pi400. Using Thonny editor. Did full install as recommended and now have Pimoroni directory installed with GFX folder and examples shown. Running any examples results in 6 error codes shown in the shell.Hello world shows touch.on(X, handler) Line …

Looks like there’s an open issue regarding this error here: Examples fail to run with error "AttributeError: 'AsyncWorker' object has no attribute 'isAlive'" opened 01:26PM - 29 Mar 22 UTC (UTC) [aunitt] …

updating the library has helped tremendously. now display lights okay when hello world run. scanning contrast example reports no contrast attribute in gfxhat.lcd and upinout can not find the yam module. Menu option works and so does touch. Any ideas…

Traceback (most recent call last): File “/home/pi/Pimoroni/gfxhat/examples/contrast-scanner.py”, line 60, in lcd.contrast(0) AttributeError: module ‘gfxhat.lcd’ has no attribute ‘contrast’

Thanks - perhaps pip install pyyaml for the first one?

is there something missing in the install command ? terminal reports missing destination file operand after pyyam1. nb I am a real beginner at this game so don’t assume I know anything…

The contrast scanner now appears to work after entering the changes with a little adjustment to python version numbers. going good here so far.

Have got the pyyaml installed now, my error I think. The example upinout now fails with the following; Traceback (most recent call last): File “/home/pi/Pimoroni/gfxhat/examples/upinout/upinout.py”, line 24, in pinout = yaml.load(open(“pinout.yaml”).read()) TypeError: load() missing 1 required…

Thread that might be relevant to the second one here - looks like the one line installer might be serving up an out of date version of the library? Gfx-hat contrast problems
