@par Example Description 

This example provides a description of how to use the STM32L1xx LCD embedded GLASS
controller to drive the Pacific Display LCD glass (PD-878) mounted on
STM32L152-EVAL board and to drive the LCD XHO5002B mounted on STM32L152D-EVAL board.
The goal of this example is to display a "STM32L" string on LCD glass in scrolling
mode. The scrolling number is fixed to 20 repetition.

@par Directory contents 

  - LCD/LCD_SegmentsDrive/stm32l1xx_conf.h     Library Configuration file
  - LCD/LCD_SegmentsDrive/stm32l1xx_it.c       Interrupt handlers

@note The "system_stm32l1xx.c" is generated by an automatic clock configuration 
      system and can be easily customized to your own configuration. 
      To select different clock setup, use the "STM32L1xx_Clock_Configuration_V1.1.0.xls" 
      provided with the AN3309 package available on <a href="http://www.st.com/internet/mcu/family/141.jsp">  ST Microcontrollers </a>
         
@par Hardware and Software environment

  - This example runs on STM32L1xx Ultra Low Power High-, Medium-Density and Medium-Density Plus Devices.
  
  - This example has been tested with STMicroelectronics STM32L152D-EVAL (STM32L1xx 
    Ultra Low Power High-Density) and STM32L152-EVAL (STM32L1xx Ultra Low 
    Power Medium-Density) evaluation board and can be easily tailored to any 
    other supported device and development board.

  - STM32L152D-EVAL Set-up
    - Make sure that the LCD GLASS board (MB979) is in LCD position.

  - STM32L152-EVAL Set-up
    - LCD Glass pins is shared with USART3 via jumpers, so make sure that
         Jumper 7 (JP7) is in position 1<-->2.
         Jumper 8 (JP8) is in position 1<-->2.

@par How to use it ? 

In order to make the program work, you must do the following :
 - Copy all source files from this example folder to the template folder under
   Project\STM32L1xx_StdPeriph_Templates
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Run the example

@note
- Ultra Low Power Medium-density devices are STM32L151xx and STM32L152xx 
  microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
- Ultra Low Power Medium-density Plus devices are STM32L151xx, STM32L152xx and 
  STM32L162xx microcontrollers where the Flash memory density is 256 Kbytes.
- Ultra Low Power High-density devices are STM32L151xx, STM32L152xx and STM32L162xx 
  microcontrollers where the Flash memory density is 384 Kbytes.
