I'm working on a personal project, essentially to prove to myself I can.
and Sheesh, I'm having some edge-detect GPIO Issues. I've searched Google, and from what I can tell, it's an error or planned depreciation in the latest ( 3-15-2024 ) build of PiOS. something something kernel related or something I'm doing because I'm a novice. I'd try a older system image but I have no idea how to setup ssh and wireless without the Pi Tool, and the tuts I found online were incomplete.![:shock:]( "Shocked")
Here's a summary of my current GPIO & python venv Setup:
1. 2 pins on PWM controlling a motor direction
2. I've hooked up the MCP3008 ADC per docs, and am reading it successfully, plotting results in pyplot
3. I need one pin to run edge detection from an encoder of a DC Motor, going to count pulses
4. I've installed stuff nto my venv that I didn't need to, but I don't call them in my script, and the errors didn't seem relevent
5. If you suspect it's my code, here it is.
Troubleshooting steps:
1. I've tried different GPIO Pins, Double checked wiring
2. Tried Sudo/Root, had issues with packages
3. sudo reboot & power cycled
4. tried RPi-lgpio ( gets error below )
5. Google
Relevent info:
1. Encoder pulses high @ 3.3v ( 60 times for every rotation of motor but the pin hasn't even seen that yet, because the script hasn't ran - it's thrown at enabling the Edge Detection before it powers up the motor.
2. Other GPi.GPIO tools work, like .pwm and .setmode, .setup
3. Running python3 in fresh venv. ( requirements.txt linked above )
I tried uninstalling RPi-GPIO and installing RPi-lgpio in my venv, but I'm getting this ![:shock:]( "Shocked")
I don't mean to sound jaded, but I hope it's some silly issue that I'm not seeing, that someone can point out to me.![:geek:]( "Geek")
but it seems like RPi.GPIO is depreciated, and RPi.Lgpio has bugs with the latest build of the kernel.
Thanks to whomever take the time to help!
