Jerome Coutant 2:123b894b49dd 38 User NOTES
Jerome Coutant 2:123b894b49dd 39 1. How To use this driver:
Jerome Coutant 2:123b894b49dd 40 --------------------------
Jerome Coutant 2:123b894b49dd 41 - This driver is used to drive directly in video mode a LCD TFT using the DSI interface.
Jerome Coutant 2:123b894b49dd 42 The following IPs are implied : DSI Host IP block working
Jerome Coutant 2:123b894b49dd 43 in conjunction to the LTDC controller.
Jerome Coutant 2:123b894b49dd 44 - This driver is linked by construction to LCD KoD mounted on board MB1166.
Jerome Coutant 2:123b894b49dd 45
Jerome Coutant 2:123b894b49dd 46 2. Driver description:
Jerome Coutant 2:123b894b49dd 47 ---------------------
Jerome Coutant 2:123b894b49dd 48 + Initialization steps:
Jerome Coutant 2:123b894b49dd 49 o Initialize the LCD using the BSP_LCD_Init() function.
Jerome Coutant 2:123b894b49dd 50 o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
Jerome Coutant 2:123b894b49dd 51 o Enable the LCD display using the BSP_LCD_DisplayOn() function.
Jerome Coutant 2:123b894b49dd 52
Jerome Coutant 2:123b894b49dd 53 + Options
Jerome Coutant 2:123b894b49dd 54 o Configure and enable the color keying functionality using the
Jerome Coutant 2:123b894b49dd 55 BSP_LCD_SetColorKeying() function.
Jerome Coutant 2:123b894b49dd 56 o Modify in the fly the transparency and/or the frame buffer address
Jerome Coutant 2:123b894b49dd 57 using the following functions:
Jerome Coutant 2:123b894b49dd 58 - BSP_LCD_SetTransparency()
Jerome Coutant 2:123b894b49dd 59 - BSP_LCD_SetLayerAddress()
Jerome Coutant 2:123b894b49dd 60
Jerome Coutant 2:123b894b49dd 61 + Display on LCD
Jerome Coutant 2:123b894b49dd 62 o Clear the whole LCD using BSP_LCD_Clear() function or only one specified string
Jerome Coutant 2:123b894b49dd 63 line using the BSP_LCD_ClearStringLine() function.
Jerome Coutant 2:123b894b49dd 64 o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
Jerome Coutant 2:123b894b49dd 65 function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
Jerome Coutant 2:123b894b49dd 66 o Display a string line on the specified position (x,y in pixel) and align mode
Jerome Coutant 2:123b894b49dd 67 using the BSP_LCD_DisplayStringAtLine() function.
Jerome Coutant 2:123b894b49dd 68 o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
Jerome Coutant 2:123b894b49dd 69 on LCD using the available set of functions.
