  ==============================================================================
                        ##### How to use this driver #####
  ==============================================================================   
      [..] The LCD HAL driver can be used as follows:
    
      (#) Declare a LCD_HandleTypeDef handle structure.

      (#) Initialize the LCD low level resources by implement the HAL_LCD_MspInit() API:
          (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
               (+) Use RCC function HAL_RCCEx_PeriphCLKConfig in indicating RCC_PERIPHCLK_LCD and 
                  selected clock source (HSE, LSI or LSE)
             
      -@- The frequency generator allows you to achieve various LCD frame rates 
            starting from an LCD input clock frequency (LCDCLK) which can vary 
            from 32 kHz up to 1 MHz.
          (##) LCD pins configuration:
              (+) Enable the clock for the LCD GPIOs.
              (+) Configure these LCD pins as alternate function no-pull.
          (##) Enable the LCD interface clock.

      (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
           Voltage Source, Dead Time, Pulse On Duration and Contrast in the hlcd Init structure.

      (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.

      -@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
          by calling the custumed HAL_LCD_MspInit() API.
      -@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared

      (#) Optionally you can update the LCD configuration using these macros:
              (+) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
              (+) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
              (+) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro  
              (+) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
              (+) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro  

      (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
          more time to update the different LCD RAM registers before calling 
          HAL_LCD_UpdateDisplayRequest() API.

      (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.

      (#) When LCD RAM memory is updated enable the update display request using
          the HAL_LCD_UpdateDisplayRequest() API.

      [..] LCD and low power modes:
           (#) The LCD remain active during STOP mode.

 ===============================================================================
                      ##### IO operation functions #####
 ===============================================================================  
 [..] Using its double buffer memory the LCD controller ensures the coherency of the 
 displayed information without having to use interrupts to control LCD_RAM 
 modification.
 The application software can access the first buffer level (LCD_RAM) through 
 the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
 it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
 This UDR flag (update display request) requests the updated information to be 
 moved into the second buffer level (LCD_DISPLAY).
 This operation is done synchronously with the frame (at the beginning of the 
 next frame), until the update is completed, the LCD_RAM is write protected and 
 the UDR flag stays high.
 Once the update is completed another flag (UDD - Update Display Done) is set and
 generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
 The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one 
 even frame.
 The update will not occur (UDR = 1 and UDD = 0) until the display is 
 enabled (LCDEN = 1).
