@par Example Description
How to use the DAC peripheral to do a simple conversion.
The conversion is done in 8 bits right alignment. The result of the conversion
of 0xFF value can be seen by connecting PA4(DAC channel1) to an oscilloscope.
The observed value is 3.3V.
STM3210E-EVAL RevD board's LEDs can be used to monitor the process status:
- LED3 is ON and example is stopped (using infinite loop)
when there is an error during process.
@note Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds)
based on variable incremented in SysTick ISR. This implies that if HAL_Delay() is called from
a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower)
than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.
@note The application need to ensure that the SysTick time base is always set to 1 millisecond
to have correct HAL operation.

@par Hardware and Software environment
- This example runs on STM32F1xx devices.
- This example has been tested with STM3210E-EVAL RevD board and can be
easily tailored to any other supported device and development board.
- STM3210E-EVAL RevD Set-up
- Connect PA4 (DAC Channel1) - connected to PA4 on Eval board Connector (pin 21 in CN11) - to an oscilloscope.
@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
