bogdanm 0:9b334a45a8ff 15 ==============================================================================
bogdanm 0:9b334a45a8ff 16 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 17 ==============================================================================
mbed_official 113:b3775bf36a83 18 [..] The LCD HAL driver can be used as follow:
bogdanm 0:9b334a45a8ff 19
bogdanm 0:9b334a45a8ff 20 (#) Declare a LCD_HandleTypeDef handle structure.
bogdanm 0:9b334a45a8ff 21
mbed_official 113:b3775bf36a83 22 (#) Prepare the initialization of the LCD low level resources by implementing your HAL_LCD_MspInit() API:
mbed_official 113:b3775bf36a83 23 (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, use the RCC function
mbed_official 113:b3775bf36a83 24 HAL_RCCEx_PeriphCLKConfig, indicating here RCC_PERIPHCLK_LCD and the selected clock
mbed_official 113:b3775bf36a83 25 source (HSE, LSI or LSE)
mbed_official 113:b3775bf36a83 26 (##) The frequency generator allows you to achieve various LCD frame rates starting from an
mbed_official 113:b3775bf36a83 27 LCD input clock frequency (LCDCLK) which can vary from 32 kHz up to 1 MHz.
bogdanm 0:9b334a45a8ff 28 (##) LCD pins configuration:
mbed_official 113:b3775bf36a83 29 - Enable the clock for the LCD GPIOs
mbed_official 113:b3775bf36a83 30 - Configure these LCD pins as alternate function no-pull.
bogdanm 0:9b334a45a8ff 31 (##) Enable the LCD interface clock.
bogdanm 0:9b334a45a8ff 32
mbed_official 113:b3775bf36a83 33 (#) Set the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias, Voltage Source,
mbed_official 113:b3775bf36a83 34 Dead Time, Pulse On Duration and Contrast in the hlcd Init structure.
bogdanm 0:9b334a45a8ff 35
bogdanm 0:9b334a45a8ff 36 (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
mbed_official 113:b3775bf36a83 37 (##) The HAL_LCD_Init() API configures the low level Hardware (GPIO, CLOCK, ...etc)
mbed_official 113:b3775bf36a83 38 by calling the user customized HAL_LCD_MspInit() API.
mbed_official 113:b3775bf36a83 39 (#) After calling the HAL_LCD_Init() the LCD RAM memory is cleared
bogdanm 0:9b334a45a8ff 40
bogdanm 0:9b334a45a8ff 41 (#) Optionally you can update the LCD configuration using these macros:
mbed_official 113:b3775bf36a83 42 (##) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
mbed_official 113:b3775bf36a83 43 (##) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
mbed_official 113:b3775bf36a83 44 (##) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
mbed_official 113:b3775bf36a83 45 (##) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
mbed_official 113:b3775bf36a83 46 (##) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
bogdanm 0:9b334a45a8ff 47
bogdanm 0:9b334a45a8ff 48 (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
mbed_official 113:b3775bf36a83 49 several times to update the different LCD RAM registers before calling
bogdanm 0:9b334a45a8ff 50 HAL_LCD_UpdateDisplayRequest() API.
bogdanm 0:9b334a45a8ff 51
bogdanm 0:9b334a45a8ff 52 (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
bogdanm 0:9b334a45a8ff 53
mbed_official 113:b3775bf36a83 54 (#) When the LCD RAM memory is updated, enable the update display request calling
bogdanm 0:9b334a45a8ff 55 the HAL_LCD_UpdateDisplayRequest() API.
bogdanm 0:9b334a45a8ff 56
mbed_official 113:b3775bf36a83 57 [..] LCD and low power modes: The LCD remain active during STOP mode.

bogdanm 0:9b334a45a8ff 342 ===============================================================================
bogdanm 0:9b334a45a8ff 343 [..] Using its double buffer memory the LCD controller ensures the coherency of the
bogdanm 0:9b334a45a8ff 344 displayed information without having to use interrupts to control LCD_RAM
bogdanm 0:9b334a45a8ff 345 modification.
bogdanm 0:9b334a45a8ff 346 The application software can access the first buffer level (LCD_RAM) through
bogdanm 0:9b334a45a8ff 347 the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
bogdanm 0:9b334a45a8ff 348 it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
bogdanm 0:9b334a45a8ff 349 This UDR flag (update display request) requests the updated information to be
bogdanm 0:9b334a45a8ff 350 moved into the second buffer level (LCD_DISPLAY).
bogdanm 0:9b334a45a8ff 351 This operation is done synchronously with the frame (at the beginning of the
bogdanm 0:9b334a45a8ff 352 next frame), until the update is completed, the LCD_RAM is write protected and
bogdanm 0:9b334a45a8ff 353 the UDR flag stays high.
bogdanm 0:9b334a45a8ff 354 Once the update is completed another flag (UDD - Update Display Done) is set and
bogdanm 0:9b334a45a8ff 355 generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
bogdanm 0:9b334a45a8ff 356 The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
bogdanm 0:9b334a45a8ff 357 even frame.
bogdanm 0:9b334a45a8ff 358 The update will not occur (UDR = 1 and UDD = 0) until the display is
bogdanm 0:9b334a45a8ff 359 enabled (LCDEN = 1).
