Re: ULP - Error: relocation out of range

I was not able to solve this issue, so if someone stumbles over this problem - i bypassed it by defining a label at another point in the code (that is not reachable in another way). Jumping there - executing the code snippet I wanted to run and Jumping back to where I came from...

does a lot more than I tried to do in the code I posted.

The thing is - when I call the hall_sensor_read() function from the ULP context it returns the same value as the one I get calling the functions from my seconds code snippet.

Hi,

I'm trying to get the current measurments from the hall sensor in ULP Mode.

When I'm reading them from a context outside the deep sleep mode like this:


adc1_config_width(ADC_WIDTH_12Bit);
hall_sensor_read();


I get values that change when a magnet is getting closer.

When I try to read ...

Wake Up - ADC - Hall Sensor

Hi,
for a prototyping project I'm looking for a developer that can help us.

It is an university project, improving the hygiene in the health care sector.

I need the ESP32 to wake up from the deep sleep mode if the hall sensor detects a measurement over a certain threshold. My understanding ist ...
