CS1237 24-bit ADC, a potential HX711 alternative!
In this video, I show you this small, but powerful 24-bit ADC. This chip could be a good replacement for the well-known HX711 chip, especially because it can achieve much higher sampling rates.

It would be nice to see the PIO used for this application on the RP2040. I've written the reverse, a HX711 emulator on the RP2040 for a hardware in the loop test tool. It enables me to simulate a strain gauge input and demand whatever mass I need to perform a test. I use the Pico SDK which is excellent and well-documented.
Whats it's sample rate?
One side of R1 is connected to AVDD can you tell where the other side of R1 is connected?
Very nice job! but isn' t it too noisy? 24 bits declared, but it seems that noise free are far way low than declared... or is it just because there is basically no filtering???
Is it possible to dynamically change the reference voltage. Of this ADC ? Is it the AVDD pin ? If i apply to it different voltages. Would it be. The Vref ? If yes. What is the range of voltages i can apply to it
A very detailed and interesting video, thank you!
what is sampling frequency you read
Can you make a video about hx as normal adc with esp32?
Is the pinout diagram at
If i test out your code on a fresh made project one error occurs<
