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... So I am still look...

Reading Hall Sensor Values from ULP

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 those value...

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, that...
