/* How To use this driver:
--------------------------
- This driver is used to drive directly a LCD TFT using the DSI interface.
The following IPs are implied : DSI Host IP block working in conjunction to the
LTDC controller.
- This driver is linked by construction to LCD KoD mounted on MB1166 daughter board.
- This driver is also used to drive monitors using HDMI interface.
Driver description:
---------------------
+ Initialization steps:
o Initialize the LCD in default mode using the BSP_LCD_Init() function with the
following settings:
- DSI is configured in video mode
- Pixelformat : LCD_PIXEL_FORMAT_RBG888
- Orientation : LCD_ORIENTATION_LANDSCAPE.
- Width : LCD_DEFAULT_WIDTH (800)
- Height : LCD_DEFAULT_HEIGHT(480)
The default LTDC layer configured is layer 0.
BSP_LCD_Init() includes DSI, LTDC, LTDC Layer and clock configurations by calling:
- MX_LTDC_ClockConfig()
- MX_LTDC_Init()
- MX_DSIHOST_DSI_Init()
- MX_LTDC_ConfigLayer()
o Initialize the LCD with required parameters using the BSP_LCD_InitEx() function.
To initialize DSI in command mode, user have to override MX_DSIHOST_DSI_Init(), weak function,
content at application level.
o Initialize the display with HDMI using BSP_LCD_InitHDMI(). Two display formats
are supported: HDMI_FORMAT_720_480 or HDMI_FORMAT_720_576
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_Reload(). 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_Reload() with ReloadType parameter set to BSP_LCD_RELOAD_NONE
- Configure LTDC (color keying, transparency ..)
- Call BSP_LCD_Reload() 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 STM32H747I_DISCO board, there's one instance. Then, this
parameter should be 0.
