/* CONTROL VIA TWO POTENTIOMETERS /* CONTROL VIA TWO POTENTIOMETERS
* ADC-calibration to cover the full poti-range: * Connect potis to left sensor board cable (0 to 3.3V) (do NOT use the red 15V wire!)
* Connect potis to left sensor board cable (0 to 3.3V) (do NOT use the red 15V wire in the cable!). see <How to calibrate>. *
* Turn the potis to minimum position, write value 1 to ADC1_MIN and value 2 to ADC2_MIN * Auto-calibration of the ADC Limit to finds the Minimum, Maximum, and Middle for the ADC input
* Turn the potis to maximum position, write value 1 to ADC1_MAX and value 2 to ADC2_MAX * Procedure:
* For middle resting potis: Let the potis in the middle resting position, write value 1 to ADC1_MID and value 2 to ADC2_MID * - press the power button for more than 5 sec and release after the beep sound
* Make, flash and test it. * - move the potentiometers freely to the min and max limits repeatedly
* - release potentiometers to the resting postion
* - press the power button to confirm or wait for the 20 sec timeout
* The Values will be saved to flash. Values are persistent if you flash with platformio. To erase them, make a full chip erase.
*
* After calibration you can optionally write the values to the following defines
* Procedure:
* - connect gnd, rx and tx of a usb-uart converter in 3.3V mode to the right sensor board cable (do NOT use the red 15V wire!)
* - readout values using a serial terminal in 38400 boud
* - turn the potis to minimum position, write value 1 to INPUT1_MIN and value 2 to INPUT2_MIN
* - turn the potis to maximum position, write value 1 to INPUT1_MAX and value 2 to INPUT2_MAX
* - for middle resting potis: Let the potis in the middle resting position, write value 1 to INPUT1_MID and value 2 to INPUT2_MID
