@par Example Description 

This example provides a description of how to use the different BSP drivers. 

At the beginning of the main program the HAL_Init() function is called to reset 
all the peripherals, initialize the Flash interface and the systick.
Then the SystemClock_Config() function is used to configure the system
clock (SYSCLK) to run at 72 MHz.

This example shows how to use the different functionalities of components 
available on the board by switching between all tests using key button. 

 ** Push the User button to start first Test.  
Blue Led (LD4) will blink between each test.Press user key to start another test:

 ** JOYSTICK **
Use the joystick button to move a pointer inside a rectangle 
(up/down/right/left) and change the pointer color(select).

 ** TOUCHSCREEN **
This example shows how to use the different Touchscreen features.
After the touchscreen calibration, use the touchscreen 
functionality to activate all colored circles inside a rectangle..

 ** LCD **
This example shows how to use the different LCD features to display string
with different fonts, to display different shapes and to draw a bitmap.

 ** SD **
This example shows how to erase, write and read the SD card and also 
how to detect the presence of the card.

 ** MEMS ACCELERO **
This example shows how to use accelerometer mems. You need to color all the
circles in moving boards: right/left//back/front

 ** EEPROM **
This example show how to read and write data in EEPROM I2C M24CXX connected on STM3210C-EVAL RevC
   * The I2C EEPROM memory (M24CXX) is directly mounted on STM3210C-EVAL RevC

 ** AUDIO PLAY **
This example show how to play/pause/resume or change the volume (min 50% / max 100 %)
of an audio playback using Key or Joystick button.

      Plug a headphone to ear the sound  /!\ Take care of yours ears.
      Default volume is 60%.
      A press of JOY_SEL button will pause the audio file play (LED 1 green keep previous state
       and LED2 orange ON).
      Another press on JOY_SEL button will resumes audio file play (only LED 1 green blink at each replay)
      @Note: Copy file 'audio.bin' (available in Utilities\Media\AudioFile folder) directly in the flash 
      at @0x08015000 using ST-Link utility


 ** LCD LOG **
This example show how to use the LCD log features.

@par Hardware and Software environment  

  - This example runs on STM32F107xC devices.
    
  - This example has been tested with STMicroelectronics STM3210C-EVAL RevC
    evaluation boards 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
