@dc42 said in Duet3 mini -> fastest read interval temperature-sensors?:

@L_B_ RRF produces a reading for each temperature sensor every 250ms. You could read them more often if you compile the firmware yourself. The constant that controls it is this line in file CANlib/src/RRF3Common.h:

constexpr uint32_t HeatSampleIntervalMillis = 250; // interval between taking temperature samples

You might also need to reduce the number of ADC readings averaged per reading.

-> Could you please be kind to point me to where to find the Analog-digital-conversion (I assume) readings averaged per reading...?
