/* How To use this driver:
|
|
-----------------------
|
|
- This driver is used to drive directly an LCD TFT using the LTDC controller.
|
|
- This driver uses timing and setting for RK043FN48H LCD.
|
|
|
|
Driver description:
|
|
------------------
|
|
+ Initialization steps:
|
|
o Initialize the LCD in default mode using the BSP_LCD_Init() function with the
|
|
following settings:
|
|
- Pixelformat : LCD_PIXEL_FORMAT_RGB888
|
|
- Orientation : LCD_ORIENTATION_LANDSCAPE.
|
|
- Width : LCD_DEFAULT_WIDTH (480)
|
|
- Height : LCD_DEFAULT_HEIGHT(272)
|
|
The default LTDC layer configured is layer 0.
|
|
BSP_LCD_Init() includes LTDC, LTDC Layer and clock configurations by calling:
|
|
- MX_LTDC_ClockConfig()
|
|
- MX_LTDC_Init()
|
|
- MX_LTDC_ConfigLayer()
|
|
|
|
o Initialize the LCD with required parameters using the BSP_LCD_InitEx() function.
|
|
|
|
o Select the LCD layer to be activated using the BSP_LCD_SetActiveLayer() function.
|
|
o Enable the LCD display using the BSP_LCD_DisplayOn() function.
|
|
o Disable the LCD display using the BSP_LCD_DisplayOff() function.
|
|
o Set the display brightness using the BSP_LCD_SetBrightness() function.
|
|
o Get the display brightness using the BSP_LCD_GetBrightness() function.
|
|
o Write a pixel to the LCD memory using the BSP_LCD_WritePixel() function.
|
|
o Read a pixel from the LCD memory using the BSP_LCD_ReadPixel() function.
|
|
o Draw an horizontal line using the BSP_LCD_DrawHLine() function.
|
|
o Draw a vertical line using the BSP_LCD_DrawVLine() function.
|
|
o Draw a bitmap image using the BSP_LCD_DrawBitmap() function.
|
|
|
|
+ Options
|
|
o Configure the LTDC reload mode by calling BSP_LCD_Relaod(). By default, the
|
|
reload mode is set to BSP_LCD_RELOAD_IMMEDIATE then LTDC is reloaded immediately.
|
|
To control the reload mode:
|
|
- Call BSP_LCD_Relaod() with ReloadType parameter set to BSP_LCD_RELOAD_NONE
|
|
- Configure LTDC (color keying, transparency ..)
|
|
- Call BSP_LCD_Relaod() with ReloadType parameter set to BSP_LCD_RELOAD_IMMEDIATE
|
|
for immediate reload or BSP_LCD_RELOAD_VERTICAL_BLANKING for LTDC reload
|
|
in the next vertical blanking
|
|
o Configure LTDC layers using BSP_LCD_ConfigLayer()
|
|
o Control layer visibility using BSP_LCD_SetLayerVisible()
|
|
o Configure and enable the color keying functionality using the
|
|
BSP_LCD_SetColorKeying() function.
|
|
o Disable the color keying functionality using the BSP_LCD_ResetColorKeying() function.
|
|
o Modify on the fly the transparency and/or the frame buffer address
|
|
using the following functions:
|
|
- BSP_LCD_SetTransparency()
|
|
- BSP_LCD_SetLayerAddress()
|
|
|
|
+ Display on LCD
|
|
o To draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
|
|
on LCD and display text, utility basic_gui.c/.h must be called. Once the LCD is initialized,
|
|
user should call GUI_SetFuncDriver() API to link board LCD drivers to BASIC GUI LCD drivers.
|
|
The basic gui services, defined in basic_gui utility, are ready for use.
|
|
|
|
Note:
|
|
--------
|
|
Regarding the "Instance" parameter, needed for all functions, it is used to select
|
|
an LCD instance. On the STM32H7B3I-DK board, there's one instance. Then, this
|
|
parameter should be 0.
