@par Example Description 

This example provides a short description of how to use the DAC peripheral to 
do a simple conversion.

- Test description:
This example provides a short description of how to use the DAC peripheral to 
do a simple conversion in 8 bits right alignment of 0xFF value, the result of 
conversion can be seen by connecting PA4(DAC channel1) to an oscilloscope.
The observed value is 3.3V.

As PA4 is connected to other device on the eval board (Potentiometer and Camera) the analog output may be corrupted.
In case please remove camera module and/or move RV1 potentiometer 

STM32469I-EVAL 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 The connection of the LCD reset pin to a dedicated GPIO PK7 instead of the STM32F469 NRST pin may cause residual display on LCD with applications/examples that do not require display.
	  The LCD clear can be ensured by hardware through the board's power off/power on or by software calling the BSP_LCD_Reset() function.

@par Hardware and Software environment  
  - This example runs on STM32F469xx/STM32F479xx devices.
    
  - This example has been tested and validated with STM32469I-EVAL RevC board and can be
    easily tailored to any other supported device and development board.

  - STM32469I-EVAL RevC Set-up
    
      - Connect PA4 (DAC Channel1) on eval board connector (pin 21 in CN5) 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
