elmot 1:d0dfbce63a89 15 ==============================================================================
elmot 1:d0dfbce63a89 16 ##### How to use this driver #####
elmot 1:d0dfbce63a89 17 ==============================================================================
elmot 1:d0dfbce63a89 18 [..] The LCD HAL driver can be used as follows:
elmot 1:d0dfbce63a89 19
elmot 1:d0dfbce63a89 20 (#) Declare a LCD_HandleTypeDef handle structure.
elmot 1:d0dfbce63a89 21
elmot 1:d0dfbce63a89 22 -@- The frequency generator allows you to achieve various LCD frame rates
elmot 1:d0dfbce63a89 23 starting from an LCD input clock frequency (LCDCLK) which can vary
elmot 1:d0dfbce63a89 24 from 32 kHz up to 1 MHz.
elmot 1:d0dfbce63a89 25
elmot 1:d0dfbce63a89 26 (#) Initialize the LCD low level resources by implementing the HAL_LCD_MspInit() API:
elmot 1:d0dfbce63a89 27
elmot 1:d0dfbce63a89 28 (++) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
elmot 1:d0dfbce63a89 29 (+++) Use RCC function HAL_RCCEx_PeriphCLKConfig in indicating RCC_PERIPHCLK_LCD and
elmot 1:d0dfbce63a89 30 selected clock source (HSE, LSI or LSE)
elmot 1:d0dfbce63a89 31
elmot 1:d0dfbce63a89 32 (++) LCD pins configuration:
elmot 1:d0dfbce63a89 33 (+++) Enable the clock for the LCD GPIOs.
elmot 1:d0dfbce63a89 34 (+++) Configure these LCD pins as alternate function no-pull.
elmot 1:d0dfbce63a89 35 (++) Enable the LCD interface clock.
elmot 1:d0dfbce63a89 36
elmot 1:d0dfbce63a89 37
elmot 1:d0dfbce63a89 38 (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
elmot 1:d0dfbce63a89 39 Voltage Source, Dead Time, Pulse On Duration, Contrast, High drive and Multiplexer
elmot 1:d0dfbce63a89 40 Segment in the Init structure of the LCD handle.
elmot 1:d0dfbce63a89 41
elmot 1:d0dfbce63a89 42 (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
elmot 1:d0dfbce63a89 43
elmot 1:d0dfbce63a89 44 -@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
elmot 1:d0dfbce63a89 45 by calling the customized HAL_LCD_MspInit() API.
elmot 1:d0dfbce63a89 46 -@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared
elmot 1:d0dfbce63a89 47
elmot 1:d0dfbce63a89 48 (#) Optionally you can update the LCD configuration using these macros:
elmot 1:d0dfbce63a89 49 (++) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
elmot 1:d0dfbce63a89 50 (++) Voltage output buffer using __HAL_LCD_VOLTAGE_BUFFER_ENABLE() and __HAL_LCD_VOLTAGE_BUFFER_DISABLE() macros
elmot 1:d0dfbce63a89 51 (++) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
elmot 1:d0dfbce63a89 52 (++) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
elmot 1:d0dfbce63a89 53 (++) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
elmot 1:d0dfbce63a89 54 (++) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
elmot 1:d0dfbce63a89 55
elmot 1:d0dfbce63a89 56 (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
elmot 1:d0dfbce63a89 57 more time to update the different LCD RAM registers before calling
elmot 1:d0dfbce63a89 58 HAL_LCD_UpdateDisplayRequest() API.
elmot 1:d0dfbce63a89 59
elmot 1:d0dfbce63a89 60 (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
elmot 1:d0dfbce63a89 61
elmot 1:d0dfbce63a89 62 (#) When LCD RAM memory is updated enable the update display request using
elmot 1:d0dfbce63a89 63 the HAL_LCD_UpdateDisplayRequest() API.
elmot 1:d0dfbce63a89 64
elmot 1:d0dfbce63a89 65 [..] LCD and low power modes:
elmot 1:d0dfbce63a89 66 (#) The LCD remain active during Sleep, Low Power run, Low Power Sleep and
elmot 1:d0dfbce63a89 67 STOP modes.

elmot 1:d0dfbce63a89 340 ##### IO operation functions #####
elmot 1:d0dfbce63a89 341 ===============================================================================
elmot 1:d0dfbce63a89 342 [..] Using its double buffer memory the LCD controller ensures the coherency of the
elmot 1:d0dfbce63a89 343 displayed information without having to use interrupts to control LCD_RAM
elmot 1:d0dfbce63a89 344 modification.
elmot 1:d0dfbce63a89 345 The application software can access the first buffer level (LCD_RAM) through
elmot 1:d0dfbce63a89 346 the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
elmot 1:d0dfbce63a89 347 it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
elmot 1:d0dfbce63a89 348 This UDR flag (update display request) requests the updated information to be
elmot 1:d0dfbce63a89 349 moved into the second buffer level (LCD_DISPLAY).
elmot 1:d0dfbce63a89 350 This operation is done synchronously with the frame (at the beginning of the
elmot 1:d0dfbce63a89 351 next frame), until the update is completed, the LCD_RAM is write protected and
elmot 1:d0dfbce63a89 352 the UDR flag stays high.
elmot 1:d0dfbce63a89 353 Once the update is completed another flag (UDD - Update Display Done) is set and
elmot 1:d0dfbce63a89 354 generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
elmot 1:d0dfbce63a89 355 The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
elmot 1:d0dfbce63a89 356 even frame.
elmot 1:d0dfbce63a89 357 The update will not occur (UDR = 1 and UDD = 0) until the display is
elmot 1:d0dfbce63a89 358 enabled (LCDEN = 1).
