mbed_official 610:813dcc80987e 16 ##### How to use this driver #####
mbed_official 610:813dcc80987e 17 ==============================================================================
mbed_official 610:813dcc80987e 18 [..] The LCD HAL driver can be used as follows:
mbed_official 610:813dcc80987e 19
mbed_official 610:813dcc80987e 20 (#) Declare a LCD_HandleTypeDef handle structure.
mbed_official 610:813dcc80987e 21
mbed_official 610:813dcc80987e 22 -@- The frequency generator allows you to achieve various LCD frame rates
mbed_official 610:813dcc80987e 23 starting from an LCD input clock frequency (LCDCLK) which can vary
mbed_official 610:813dcc80987e 24 from 32 kHz up to 1 MHz.
mbed_official 610:813dcc80987e 25
mbed_official 610:813dcc80987e 26 (#) Initialize the LCD low level resources by implementing the HAL_LCD_MspInit() API:
mbed_official 610:813dcc80987e 27
mbed_official 610:813dcc80987e 28 (++) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows:
mbed_official 610:813dcc80987e 29 (+++) Use RCC function HAL_RCCEx_PeriphCLKConfig in indicating RCC_PERIPHCLK_LCD and
mbed_official 610:813dcc80987e 30 selected clock source (HSE, LSI or LSE)
mbed_official 610:813dcc80987e 31
mbed_official 610:813dcc80987e 32 (++) LCD pins configuration:
mbed_official 610:813dcc80987e 33 (+++) Enable the clock for the LCD GPIOs.
mbed_official 610:813dcc80987e 34 (+++) Configure these LCD pins as alternate function no-pull.
mbed_official 610:813dcc80987e 35 (++) Enable the LCD interface clock.
mbed_official 610:813dcc80987e 36
mbed_official 610:813dcc80987e 37
mbed_official 610:813dcc80987e 38 (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias,
mbed_official 610:813dcc80987e 39 Voltage Source, Dead Time, Pulse On Duration, Contrast, High drive and Multiplexer
mbed_official 610:813dcc80987e 40 Segment in the Init structure of the LCD handle.
mbed_official 610:813dcc80987e 41
mbed_official 610:813dcc80987e 42 (#) Initialize the LCD registers by calling the HAL_LCD_Init() API.
mbed_official 610:813dcc80987e 43
mbed_official 610:813dcc80987e 44 -@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc)
mbed_official 610:813dcc80987e 45 by calling the customized HAL_LCD_MspInit() API.
mbed_official 610:813dcc80987e 46 -@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared
mbed_official 610:813dcc80987e 47
mbed_official 610:813dcc80987e 48 (#) Optionally you can update the LCD configuration using these macros:
mbed_official 610:813dcc80987e 49 (++) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros
mbed_official 610:813dcc80987e 50 (++) Voltage output buffer using __HAL_LCD_VOLTAGE_BUFFER_ENABLE() and __HAL_LCD_VOLTAGE_BUFFER_DISABLE() macros
mbed_official 610:813dcc80987e 51 (++) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro
mbed_official 610:813dcc80987e 52 (++) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro
mbed_official 610:813dcc80987e 53 (++) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro
mbed_official 610:813dcc80987e 54 (++) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro
mbed_official 610:813dcc80987e 55
mbed_official 610:813dcc80987e 56 (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called
mbed_official 610:813dcc80987e 57 more time to update the different LCD RAM registers before calling
mbed_official 610:813dcc80987e 58 HAL_LCD_UpdateDisplayRequest() API.
mbed_official 610:813dcc80987e 59
mbed_official 610:813dcc80987e 60 (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory.
mbed_official 610:813dcc80987e 61
mbed_official 610:813dcc80987e 62 (#) When LCD RAM memory is updated enable the update display request using
mbed_official 610:813dcc80987e 63 the HAL_LCD_UpdateDisplayRequest() API.
mbed_official 610:813dcc80987e 64
mbed_official 610:813dcc80987e 65 [..] LCD and low power modes:
mbed_official 610:813dcc80987e 66 (#) The LCD remain active during Sleep, Low Power run, Low Power Sleep and
mbed_official 610:813dcc80987e 67 STOP modes.
mbed_official 610:813dcc80987e 68

mbed_official 610:813dcc80987e 336 [..] Using its double buffer memory the LCD controller ensures the coherency of the
mbed_official 610:813dcc80987e 337 displayed information without having to use interrupts to control LCD_RAM
mbed_official 610:813dcc80987e 338 modification.
mbed_official 610:813dcc80987e 339 The application software can access the first buffer level (LCD_RAM) through
mbed_official 610:813dcc80987e 340 the APB interface. Once it has modified the LCD_RAM using the HAL_LCD_Write() API,
mbed_official 610:813dcc80987e 341 it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API.
mbed_official 610:813dcc80987e 342 This UDR flag (update display request) requests the updated information to be
mbed_official 610:813dcc80987e 343 moved into the second buffer level (LCD_DISPLAY).
mbed_official 610:813dcc80987e 344 This operation is done synchronously with the frame (at the beginning of the
mbed_official 610:813dcc80987e 345 next frame), until the update is completed, the LCD_RAM is write protected and
mbed_official 610:813dcc80987e 346 the UDR flag stays high.
mbed_official 610:813dcc80987e 347 Once the update is completed another flag (UDD - Update Display Done) is set and
mbed_official 610:813dcc80987e 348 generates an interrupt if the UDDIE bit in the LCD_FCR register is set.
mbed_official 610:813dcc80987e 349 The time it takes to update LCD_DISPLAY is, in the worst case, one odd and one
mbed_official 610:813dcc80987e 350 even frame.
mbed_official 610:813dcc80987e 351 The update will not occur (UDR = 1 and UDD = 0) until the display is
mbed_official 610:813dcc80987e 352 enabled (LCDEN = 1).
