-@par Example Description
-
-How to use the different BSP drivers of external devices mounted on B-L475E-IOT01A board.
-
-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 80 MHz.
-
-This example shows how to use the different functionalities of QSPI and how to get
-information from sensors.
-It uses the hyperterminal to display information and to get orders from user. 
-At the beginning, the program waits the User Button is pressed to put LED2 ON. Once 
-this is done, it goes to run the following tests:
-
-### QSPI ###
-This example shows how to use the QSPI features(read/write/erase..).
-
-### QSPI MEMORY MAPPED ###
-This example shows how to use the QSPI features(read/write/erase..) in memory mapped
-mode.
-
-### TEMPERATURE ###
-This example shows how to use the sensors to get tempearture values. By default, 
-HTS221 is the used sensor. User can get tempearture value using LPS22HB sensor, 
-this by uncommenting the following line in main.h file:
-/* #define USE_LPS22HB_TEMP */
-
-### HUMIDITY ###
-This example shows how to use the HTS221 sensor to get humidity values.
-
-### PRESSURE ###
-This example shows how to use the LPS22HB sensor to get pressure values.
-
-### MAGNETO ###
-This example shows how to use the LIS3MDL sensor to get magnetometer values.
-
-### GYROSCOPE ###
-This example shows how to use the LIS3MDL sensor to get gyroscope values.
-
-### ACCELERO ###
-This example shows how to use the LSM6DSL sensor to get accelerometer values.
-
-@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 STM32L475xx devices.
-    
-  - This example has been tested with STMicroelectronics B-L475E-IOT01A
-    boards.
-
-
-@par How to use it ? 
-
-In order to make the program work, you must do the following :
- - Open an hyperterminal with following setting:
-    + COM: STLink Virtual COM Port(COMxxx). This can be found by opening computer
-           Device Manager, Port(COM & LPT) once the board is connected to the PC.
-    + BaudRate = 115200 baud  
-    + Word Length = 8 Bits (7 data bit + 1 parity bit)
-    + One Stop Bit
-    + Parity none
-    + Hardware flow control disabled (RTS and CTS signals)
-    + Reception and transmission are enabled in the time
-    
- - Open your preferred toolchain 
- - Rebuild all files and load your image into target memory
- - Run the example
