How do I check that a microcontroller is connecting successfully?

[/RaspberryPi]

I’m trying to create a weight scale but my sensor isn’t playing ball. I’ve been trawling online and can’t get a reliable method.

I have a Raspberry Pi 3B connected to a HX711 amp from Sparkfun that I am using with 4 strain gauges in a Wheatstone bridge configuration. I have tested my Wheatstone bridge with a multitool and can see the resistance difference so I think that’s working correctly.

However, I can’t get any readings from the HX711 that give me any results from the gauges.

How can I check that the HX711 is working as expected? Is there a way to “ping” it to verify its condition?
