HX711 working only with Analog Input pins

[Kuhaku]

Greetings.

I have a question that I hope someone can help me with. Recently, I've been working with the HX711 sensor to weigh with a certain precision. I have a custom board that uses a module integrating an nrf5340 and an nrf7002 for WiFi connectivity. The issue is that using the sensor driver from the repository https://github.com/nobodyguy/HX711_zephyr_driver, I've noticed that it only works using clock and dout pins configured as analog input. Considering that the sensor datasheet doesn't specify anything about this, I'd like to know why this happens and if it's possible to use it on non-analog pins.

Thanks in advance.

Hi,

configured as analog input

For clarity: What exactly is the code you refer to to configure these?

Hi, thanks for the answer.

I was referring to the pins that according to the pinout/datasheet are labeled as AIN. Specifically, I'm using pins 0.25, 0.26, and 0.27, but it doesn't work with pin 1.8, for example, which is not defined as AIN.

Thanks in advance.

The nRF5340 does not really have any "Analog Pins", so I suspect this is specific to the module you use.

Could it be that the module uses other pins for something else?
Have you tested other not-analog pins, or only 1.8?
