ebrus 0:6bc4ac881c8e 15 ==============================================================================
ebrus 0:6bc4ac881c8e 16 ##### How to use this driver #####
ebrus 0:6bc4ac881c8e 17 ==============================================================================
ebrus 0:6bc4ac881c8e 18 [..] The LCD HAL driver can be used as follows:
ebrus 0:6bc4ac881c8e 19
ebrus 0:6bc4ac881c8e 20 (#) Declare a LCD_HandleTypeDef handle structure.
ebrus 0:6bc4ac881c8e 21
ebrus 0:6bc4ac881c8e 22 (#) Initialize the LCD low level resources by implement the HAL_LCD_MspInit() API:
ebrus 0:6bc4ac881c8e 23 (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
ebrus 0:6bc4ac881c8e 24 (+) Enable the Power Controller (PWR) APB1 interface clock using the
ebrus 0:6bc4ac881c8e 25 __PWR_CLK_ENABLE() macro.
ebrus 0:6bc4ac881c8e 26 (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
ebrus 0:6bc4ac881c8e 27 (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
ebrus 0:6bc4ac881c8e 28
ebrus 0:6bc4ac881c8e 29 (@) The frequency generator allows you to achieve various LCD frame rates
ebrus 0:6bc4ac881c8e 30 starting from an LCD input clock frequency (LCDCLK) which can vary
ebrus 0:6bc4ac881c8e 31 from 32 kHz up to 1 MHz.
ebrus 0:6bc4ac881c8e 32 (##) LCD pins configuration:
ebrus 0:6bc4ac881c8e 33 (+) Enable the clock for the LCD GPIOs.
ebrus 0:6bc4ac881c8e 34 (+) Configure these LCD pins as alternate function no-pull.
ebrus 0:6bc4ac881c8e 35 (##) Enable the LCD interface clock.
ebrus 0:6bc4ac881c8e 36
ebrus 0:6bc4ac881c8e 37 (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
ebrus 0:6bc4ac881c8e 38 Voltage Source, Dead Time, Pulse On Duration and Contrast in the hlcd Init structure.
ebrus 0:6bc4ac881c8e 39
ebrus 0:6bc4ac881c8e 40 (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
ebrus 0:6bc4ac881c8e 41
ebrus 0:6bc4ac881c8e 42 (@) The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
ebrus 0:6bc4ac881c8e 43 by calling the custumed HAL_LCD_MspInit() API.
ebrus 0:6bc4ac881c8e 44 (@) After calling the HAL_LCD_Init() the LCD RAM memory is cleared
ebrus 0:6bc4ac881c8e 45
ebrus 0:6bc4ac881c8e 46 (#) Optionally you can update the LCD configuration using these macros:
ebrus 0:6bc4ac881c8e 47 - LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
ebrus 0:6bc4ac881c8e 48 - LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
ebrus 0:6bc4ac881c8e 49 - LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
ebrus 0:6bc4ac881c8e 50 - The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
ebrus 0:6bc4ac881c8e 51 - The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
ebrus 0:6bc4ac881c8e 52
ebrus 0:6bc4ac881c8e 53 (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
ebrus 0:6bc4ac881c8e 54 more time to update the different LCD RAM registers before calling
ebrus 0:6bc4ac881c8e 55 HAL_LCD_UpdateDisplayRequest() API.
ebrus 0:6bc4ac881c8e 56
ebrus 0:6bc4ac881c8e 57 (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
ebrus 0:6bc4ac881c8e 58
ebrus 0:6bc4ac881c8e 59 (#) When LCD RAM memory is updated enable the update display request using
ebrus 0:6bc4ac881c8e 60 the HAL_LCD_UpdateDisplayRequest() API.
ebrus 0:6bc4ac881c8e 61
ebrus 0:6bc4ac881c8e 62 [..] LCD and low power modes:
ebrus 0:6bc4ac881c8e 63 (#) The LCD still active during STOP mode.

ebrus 0:6bc4ac881c8e 309 ##### I/O operation methods #####
ebrus 0:6bc4ac881c8e 310 ===============================================================================
ebrus 0:6bc4ac881c8e 311 [..] Using its double buffer memory the LCD controller ensures the coherency of the
ebrus 0:6bc4ac881c8e 312 displayed information without having to use interrupts to control LCD_RAM
ebrus 0:6bc4ac881c8e 313 modification.
ebrus 0:6bc4ac881c8e 314 The application software can access the first buffer level (LCD_RAM) through
ebrus 0:6bc4ac881c8e 315 the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
ebrus 0:6bc4ac881c8e 316 it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
ebrus 0:6bc4ac881c8e 317 This UDR flag (update display request) requests the updated information to be
ebrus 0:6bc4ac881c8e 318 moved into the second buffer level (LCD_DISPLAY).
ebrus 0:6bc4ac881c8e 319 This operation is done synchronously with the frame (at the beginning of the
ebrus 0:6bc4ac881c8e 320 next frame), until the update is completed, the LCD_RAM is write protected and
ebrus 0:6bc4ac881c8e 321 the UDR flag stays high.
ebrus 0:6bc4ac881c8e 322 Once the update is completed another flag (UDD - Update Display Done) is set and
ebrus 0:6bc4ac881c8e 323 generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
ebrus 0:6bc4ac881c8e 324 The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
ebrus 0:6bc4ac881c8e 325 even frame.
ebrus 0:6bc4ac881c8e 326 The update will not occur (UDR = 1 and UDD = 0) until the display is
ebrus 0:6bc4ac881c8e 327 enabled (LCDEN = 1).
