Analog voltage output
c: Analog 3.3 V distance (0.00m to 50.00m) - Sets the distance at which the voltage output will show 3.3 V
d: Analog 0.0 V distance (0.00m to 50.00m) - Sets the distance at which the voltage output will show 0.0 V
Menu items <c> and <d> relate to the analog voltage output and are used to set the end point distances that correspond to the 0.0 V
and 3.3 V output voltages. These voltages are read by the ADC of the host controller and can be converted back into a distance by
using the formula:
d = v / 3.3 * (DH - DL) + DL
where:
d = measured distance
v = voltage measured by the ADC of the host
DL = 0.0V distance
DH = 3.3V distance
The range of values for both distance settings is from 0.00 meters to 50.00 meters. The analog voltage output updates at 32 readings
per second and has a 10 bit resolution.
