Using multiple HX711 with one clock

Other Hardware LEDs and Multiplexing

Hi guys,

I was wondering, does anyone have experience with using multiple HX711's? I've a bit a lack of pins on my arduino nano and i was wondering if it would be possible to just use one clock signal for all my load cells (that would save me 3 pins :p).

The simple solution to this problem would be to try it, but at the moment i only have one loadcell. Did anyone do this before?

Thanks!

Got a link to a datasheet?

Sounds to me like if you can treat the load cells the same (all channel A, same gain) then you can use the same clock signal.

If you can post your schematic, maybe we can suggest other ways to save pins on your Nano.

Hi
Have you managed to make them work on same clock pin?

I tried with 4 on a raspberry pi but have some issues

I'm looking the same.
Seems works with same pin using GitHub - compugician/HX711-multi: An Arduino library to interface multiple HX711 units simultaneously

Connect all HX711 units to share a single clock line, and plug each data line from the HX711 to a different pin on the Arduino
