@par Example Description
How to use the ADC in interrupt mode to convert data through the HAL API.
The ADC1 is configured to convert continuously ADC_CHANNEL_10.
Each time an end of conversion occurs an interrupt is generated and the converted
data of ADC1 DR register is affected to the uhADCxConvertedValue variable in the
ADC conversion complete call back function.
In this example, the system clock is 180MHz, APB2 = 90MHz and ADC clock = APB2/4.
Since ADC1 clock is 22.5 MHz and sampling time is set to 3 cycles, the conversion
time to 12bit data is 12 cycles so the total conversion time is (12+3)/22.5= 0.66us(1.5Msps).
User can vary the ADC_CHANNEL_10 voltage by applying an input voltage on pin3 connector 9
(connected to PC.00).
The converted value is monitored through debugger: uhADCxConvertedValue variable.
STM32 Nucleo boards LEDs can be used to monitor the transfer status:
- LED2 is ON when there are an error in initialization.

@par Hardware and Software environment
- This example runs on STM32F429xx devices.
- This example has been tested with NUCLEO-F429ZI Rev B board and can be
easily tailored to any other supported device and development board.
@par How to use it ?
In order to make the program work, you must do the following :
- Open your preferred toolchain
- Rebuild all files and load your image into target memory
- Run the example
