4.2.3.1
ADC raw value and initialisation value
You can configure each channel so that the raw value from the AD converter is issued dir
ectly, without calibration or scaling.
If the AD converter fails to supply a valid value, the module will adopt the ADC initialisation
value for this channel instead. The default value is 4096
D
(1000
H
).
4.2.3.2
Hardware calibration
Each channel is calibrated exworks in order to correct component dispersion and other in
fluences.
The range is divided so that zero is assigned the value 0 and the end point is assigned the
value 4095
D
(0FFF
H
).
