After installing CircuitPython, the test program fails like this:

python3 blinkatest.py

Description

Similar to adafruit/Adafruit_Blinka#907

Tried removing rpi.gpio and adding rpi-lgpio but that had already been done (I assume by the CircuitPython installer script)

Additional information

No response

Yeah, we aren't using rpi-lgpio anymore. Too many conflicts. We switched to using just lgpio. Usually an error like that means the pin is in use. I'll give it a try and see if I get the same results.

[makermelissa]

I installed and despite a number of errors (see adafruit/Adafruit_Blinka#1016), the tests appear to run fine (I ran both blinkatest.py and blinky.py).

makermelisa,

Thanks for looking at this. I re-ran the install on a fresh installation and yes, it worked. This was probably my fault as I had been fiddling around with gpiozero initially. Anyway, this worked as advertised. OK to close. Thanks again, Dave.
