Hall sensor no longer supported in ESP-IDF 5.0 - MAJOR PROBLEM

[dedvalson]

Hi,

I am finally getting our application ported to ESP-IDF 5.0.2. However I now read that the hall effect sensor is no longer supported. This is a disaster for us. We have thousands of units in the field that utilize this sensor. Our units are in a water proof case. Users use a magnet over the hall effect sensor to do resets and change modes. We do not need accuracy, just the presence or absence of the magnet.

Can you PLEASE supply me with any information I might be able to use to continue the use of hardware feature. This seemingly minor thing will prevent us from doing this upgrade unless I can work around it.

Thanks,

Don

Same question here. This is the main issue why we cannot go past IDF 4.* yet.

The PCN only says "the hall sensor on ESP32 does not work properly. Therefore, all references to hall sensor in
ESP32 documentation need to be removed."
Can someone share more details about the issue?

Email sent. Thanks.

Hi,

FWIW I created a tiny component that implements this and seems to work (with ESP_IDF 5.0.2)

It uses the legacy ADC driver so it is kind of out of date but it works (at least for me). It may not work for anyone else, no promises.

I have attached it as a .zip file here.

Hi dedvalson,

We will be very grateful if you'd like to upload your components to the ESP Registry(https://docs.espressif.com/projects/idf ... index.html) and upload the component to your github at the same time.

Then we also review your components, thanks for your contribution!
