| mbed_official | 376:cb4d9db17537 | 15 | ============================================================================== |
| mbed_official | 376:cb4d9db17537 | 16 | ##### How to use this driver ##### |
| mbed_official | 376:cb4d9db17537 | 17 | ============================================================================== |
| mbed_official | 376:cb4d9db17537 | 18 | [..] The LCD HAL driver can be used as follows: |
| mbed_official | 376:cb4d9db17537 | 19 | |
| mbed_official | 376:cb4d9db17537 | 20 | (#) Declare a LCD_HandleTypeDef handle structure. |
| mbed_official | 376:cb4d9db17537 | 21 | |
| mbed_official | 376:cb4d9db17537 | 22 | (#) Initialize the LCD low level resources by implement the HAL_LCD_MspInit() API: |
| mbed_official | 376:cb4d9db17537 | 23 | (##) Enable the LCDCLK (same as RTCCLK): to configure the RTCCLK/LCDCLK, proceed as follows: |
| mbed_official | 489:119543c9f674 | 24 | (+) Use RCC function HAL_RCCEx_PeriphCLKConfig in indicating RCC_PERIPHCLK_LCD and |
| mbed_official | 489:119543c9f674 | 25 | selected clock source (HSE, LSI or LSE) |
| mbed_official | 376:cb4d9db17537 | 26 | |
| mbed_official | 376:cb4d9db17537 | 27 | -@- The frequency generator allows you to achieve various LCD frame rates |
| mbed_official | 376:cb4d9db17537 | 28 | starting from an LCD input clock frequency (LCDCLK) which can vary |
| mbed_official | 376:cb4d9db17537 | 29 | from 32 kHz up to 1 MHz. |
| mbed_official | 376:cb4d9db17537 | 30 | (##) LCD pins configuration: |
| mbed_official | 376:cb4d9db17537 | 31 | (+) Enable the clock for the LCD GPIOs. |
| mbed_official | 376:cb4d9db17537 | 32 | (+) Configure these LCD pins as alternate function no-pull. |
| mbed_official | 376:cb4d9db17537 | 33 | (##) Enable the LCD interface clock. |
| mbed_official | 376:cb4d9db17537 | 34 | |
| mbed_official | 376:cb4d9db17537 | 35 | (#) Program the Prescaler, Divider, Blink mode, Blink Frequency Duty, Bias, |
| mbed_official | 376:cb4d9db17537 | 36 | Voltage Source, Dead Time, Pulse On Duration and Contrast in the hlcd Init structure. |
| mbed_official | 376:cb4d9db17537 | 37 | |
| mbed_official | 376:cb4d9db17537 | 38 | (#) Initialize the LCD registers by calling the HAL_LCD_Init() API. |
| mbed_official | 376:cb4d9db17537 | 39 | |
| mbed_official | 376:cb4d9db17537 | 40 | -@- The HAL_LCD_Init() API configures also the low level Hardware GPIO, CLOCK, ...etc) |
| mbed_official | 376:cb4d9db17537 | 41 | by calling the custumed HAL_LCD_MspInit() API. |
| mbed_official | 376:cb4d9db17537 | 42 | -@- After calling the HAL_LCD_Init() the LCD RAM memory is cleared |
| mbed_official | 376:cb4d9db17537 | 43 | |
| mbed_official | 376:cb4d9db17537 | 44 | (#) Optionally you can update the LCD configuration using these macros: |
| mbed_official | 376:cb4d9db17537 | 45 | (+) LCD High Drive using the __HAL_LCD_HIGHDRIVER_ENABLE() and __HAL_LCD_HIGHDRIVER_DISABLE() macros |
| mbed_official | 376:cb4d9db17537 | 46 | (+) LCD Pulse ON Duration using the __HAL_LCD_PULSEONDURATION_CONFIG() macro |
| mbed_official | 376:cb4d9db17537 | 47 | (+) LCD Dead Time using the __HAL_LCD_DEADTIME_CONFIG() macro |
| mbed_official | 376:cb4d9db17537 | 48 | (+) The LCD Blink mode and frequency using the __HAL_LCD_BLINK_CONFIG() macro |
| mbed_official | 376:cb4d9db17537 | 49 | (+) The LCD Contrast using the __HAL_LCD_CONTRAST_CONFIG() macro |
| mbed_official | 376:cb4d9db17537 | 50 | |
| mbed_official | 376:cb4d9db17537 | 51 | (#) Write to the LCD RAM memory using the HAL_LCD_Write() API, this API can be called |
| mbed_official | 376:cb4d9db17537 | 52 | more time to update the different LCD RAM registers before calling |
| mbed_official | 376:cb4d9db17537 | 53 | HAL_LCD_UpdateDisplayRequest() API. |
| mbed_official | 376:cb4d9db17537 | 54 | |
| mbed_official | 376:cb4d9db17537 | 55 | (#) The HAL_LCD_Clear() API can be used to clear the LCD RAM memory. |
| mbed_official | 376:cb4d9db17537 | 56 | |
| mbed_official | 376:cb4d9db17537 | 57 | (#) When LCD RAM memory is updated enable the update display request using |
| mbed_official | 376:cb4d9db17537 | 58 | the HAL_LCD_UpdateDisplayRequest() API. |
| mbed_official | 376:cb4d9db17537 | 59 | |

| mbed_official | 376:cb4d9db17537 | 341 | it sets the UDR flag in the LCD_SR register using the HAL_LCD_UpdateDisplayRequest() API. |

| mbed_official | 376:cb4d9db17537 | 348 | generates an interrupt if the UDDIE bit in the LCD_FCR register is set. |
