@par Example Description
How to use the ADC to perform a single ADC channel conversion at each
software start. This example uses the interrupt programming model (for
polling and DMA programming models, please refer to other examples). It is
based on the STM32WBxx ADC HAL and LL API. The LL API is used
for performance improvement.
Example configuration:
ADC is configured to convert a single channel, in single conversion mode,
from SW trigger.
ADC interruption enabled: EOC (end of conversion of ADC group regular).
Example execution:
At each press of User push-button (SW1), the ADC performs 1 conversion of the selected channel.
When conversion is completed, ADC interruption occurs.
IRQ handler callback function reads conversion data from ADC data register
and stores it into a variable, LED2 is turned on.
For debug: variables to monitor with debugger watch window:
- "uhADCxConvertedData": ADC group regular conversion data
- "uhADCxConvertedData_Voltage_mVolt": ADC conversion data computation to physical values
Connection needed:
None.
Note: Optionally, a voltage can be supplied to the analog input pin (cf pin below),
between 0V and Vdda=3.3V, to perform a ADC conversion on a determined
voltage level.
Otherwise, this pin can be let floating (in this case ADC conversion data
will be undetermined).
Other peripherals used:
1 GPIO for push button
1 GPIO for LED
1 GPIO for analog input: PA.01 (Arduino connector CN8 pin A2, Morpho connector CN7 pin 32)
