Yes I know but how can I set the sensor value manually ? Le mer. 3 mai 2023 à 17:48, David Grayson ***@***.***> a écrit :

What exactly do you mean? What have you already tried and why did it not work?

In my program I have to calibrate at each start. I want to do it only once and then always use the same values. So to do this I need to get the calibrationOn and calibrationOff values. After I get them how can I specify them manually ? Le mer. 3 mai 2023 à 17:57, David Grayson ***@***.***> a écrit :

First of all, look at the definition of struct CalibrationData in QTRSensors.h so you know what data that struct contains. Then use the C++ assignment operator (=) to set the values of each member. For examples:

sensors.calibrationOn.initialized = true;
sensors.calibrationOn.minimum = your_array_of_minima;
sensors.calibrationOn.maximum = your_array_of_maxima;

This seems like a general C++ programming question. We use GitHub issues to keep track of bugs and feature requests in the library, so if you need more help the more appropriate place to ask would be:

Note: the destructor of QTRSensors uses free to free those arrays, so you should either allocate your arrays yourself with malloc or by calling QTRSensors::calibrate (and then overwriting the values it stores in the newly-allocated arrays).
