Cube Flight Controller / ADC measurement

PX4 Autopilot Flight Controllers đź’»

I would like to use the Cube Flight Controller’s ADC port to measure a voltage from an external analog temperature sensor and have PX4 log it to the SD card.

In the datasheet the ADC port’s signal pin is named “Pressure sense in”, which (according to the schematics) is connected to the processor’s PC5, or ADC12_IN15.

Where (in PX4) can I find the reading of that pin, and how can I enable logging its value?

As adc_report is published through uORB, so you can simply log it with this instruction
You need to add adc_report in your logger_topics.txt.
