ESP32 Forum

I cannot make the Hall sensor example work, the plotter just shows noise and the sensor does not react when I approach the magnet.
The example is as simple as can be. I am using Arduino with the ESP32 extension.

I can get the ESP32-EVB to work with LEDs etc. so I have a serial connection that works.

The manual states that the Hall sensor stores its value in a register and hallRead() fetches it there, all done internally. The sketch does not show any specific pin either.

So, what have I missed? Should I include some file? IS there a special extension for the ESP32-EVB?

Such a simple sketch!!! I am going inte desperation level.
Please advise. Thank you very much in advance.

Hello.
Enter the code here

The hall sensor peripheral is inside the chip. Put the magnet right on the chip to see it react. If you have a hall sensor device, it will just be a regular input, either using ADC, SPI, or I2C (check the datasheet). Some modules/boards use pins 36 & 39, which will prevent you from using the internal hall sensor.
