Hi all
I'm currently trying to use an HX711 to read grip strength from a strain gauge load cell to my Raspberry Pi 3A+, however I cannot get any readings.
I tried using Adafruit's module for circuitpython: https://learn.adafruit.com/adafruit-hx7 ... cuitpython and cannot receive a reading.
I'm having the same issue with a python based one as well: https://github.com/tatobari/hx711py
When I try to run the example script, this is the output
I tried pulsing GPIO pins directly, but it just outputs either 0 or -1 for all readings (that is, if it takes a reading)
I have VIO connected to 3.3V, ground is connected to physical pin 6, SCK to GPIO6 (physical pin 31) and DATA to GPIO5 (physical pin 29).
Any suggestions on where to turn?
