/* | |
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 using the BSP_LCD_Init() function. | |
o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function. | |
o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function. | |
o Enable the LCD display using the BSP_LCD_DisplayOn() function. | |
+ Options | |
o Configure and enable the colour keying functionality using the | |
BSP_LCD_SetColorKeying() function. | |
o Modify in the fly the transparency and/or the frame buffer address | |
using the following functions: | |
- BSP_LCD_SetTransparency() | |
- BSP_LCD_SetLayerAddress() | |
+ Display on LCD | |
o Clear the whole LCD using BSP_LCD_Clear() function or only one specified string | |
line using the BSP_LCD_ClearStringLine() function. | |
o Display a character on the specified line and column using the BSP_LCD_DisplayChar() | |
function or a complete string line using the BSP_LCD_DisplayStringAtLine() function. | |
o Display a string line on the specified position (x,y in pixel) and align mode | |
using the BSP_LCD_DisplayStringAtLine() function. | |
o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap) | |
on LCD using the available set of functions. | |
