we would like to use the STM8T141 part for proximity sensors. The question is the following:
We need to disable the environmental compensation filter (ECF) as in our opinion this will cause troubles as the sensor application imply a a gradual change in the capacitance under observation up to the detection point and this could move the reference level along with the slow capacitance variation producing a missing detection.
For our application the reference level must be fixed and not re-setup at chip startup.
Can anyone help us on this?
