I am using GPIO pin5 & 6 (GPIO5 for DT & GPIO 6 CLK)

Tried changing power source to both with VCC 5V and 3.3V

Tried with Different set_reference_units

Hello, did you fix this problem, I am getting the same one I am using four 50kg load cell

jpadams commented 3 years ago

same

I've tested the library and it seems to be working just fine.

It's most important that you submit a schema of how you've wired the loadcells to the HX711. The 50kg loadcells everyone uses, the square ones, don't have an embedded wheatstone bridge and therefore must be connected in a wheatstone bridge layout. Posting your schema will help me help you debug your issue.

had the same issue. changing the mode from BCM to BOARD fixed it for me.

I have the same issue, but I'm using a 20kg load cell (beam type). CLK on Pin 20, DT on 21. Chip & load cell are working as intended on my Arduino, but is giving me zeros on the Raspberry
