@par Example Description
This example describes how to use a ADC peripheral to perform
a single ADC conversion of a channel, at each software start;
Example using programming model: polling
(for programming models interrupt or DMA transfer, refer to
other examples);
This example is based on the STM32F4xx ADC LL API;
peripheral initialization done using LL unitary services functions
for optimization purpose (performance and size).
Example configuration:
ADC is configured to convert a single channel, in single conversion mode,
from SW trigger.
Example execution:
At each press on User Button, the ADC performs 1 conversion of the selected channel.
Software polls for conversion completion.
When conversion is completed, main program 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 User Button
1 GPIO for LED2
1 GPIO for analog input: PA.04 (Arduino connector CN8 pin A2, Morpho connector CN7 pin 32)
