Block STM32 ADC It is used to output samples from the microcontroller’s ADC.

Ports

Output

# The counts — samples from the ADC
scalar | vector

Details

The vector of samples in the case of channels, a scalar in the case of a single channel. Dimension: () if there is only one channel, or (n,), where n — the number of ADC channels.

Data types	`uint16_t`
Complex numbers support	No

Configuring CubeMX to read analog inputs

Select the desired ADC module. In the Parameter Settings tab, select:

Scan Conversion Mode — Enabled if you need to work with multiple channels;
Continuous Conversion Mode — Disabled;
Number Of Conversion — specify a number equal to the number of channels to be polled for this ADC module;
End Of Conversion Selection — select the EOC flag at the end of all conversions.
