Jerome Coutant 0:c0f3bbab73d2 41 1. How To use this driver:
Jerome Coutant 0:c0f3bbab73d2 42 --------------------------
Jerome Coutant 0:c0f3bbab73d2 43 - This driver is used to drive directly in video mode a LCD TFT using the DSI interface.
Jerome Coutant 0:c0f3bbab73d2 44 The following IPs are implied : DSI Host IP block working
Jerome Coutant 0:c0f3bbab73d2 45 in conjunction to the LTDC controller.
Jerome Coutant 0:c0f3bbab73d2 46 - This driver is linked by construction to LCD KoD mounted on board MB1166.
Jerome Coutant 0:c0f3bbab73d2 47
Jerome Coutant 0:c0f3bbab73d2 48 2. Driver description:
Jerome Coutant 0:c0f3bbab73d2 49 ---------------------
Jerome Coutant 0:c0f3bbab73d2 50 + Initialization steps:
Jerome Coutant 0:c0f3bbab73d2 51 o Initialize the LCD using the BSP_LCD_Init() function.
Jerome Coutant 0:c0f3bbab73d2 52 o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
Jerome Coutant 0:c0f3bbab73d2 53 o Enable the LCD display using the BSP_LCD_DisplayOn() function.
Jerome Coutant 0:c0f3bbab73d2 54
Jerome Coutant 0:c0f3bbab73d2 55 + Options
Jerome Coutant 0:c0f3bbab73d2 56 o Configure and enable the color keying functionality using the
Jerome Coutant 0:c0f3bbab73d2 57 BSP_LCD_SetColorKeying() function.
Jerome Coutant 0:c0f3bbab73d2 58 o Modify in the fly the transparency and/or the frame buffer address
Jerome Coutant 0:c0f3bbab73d2 59 using the following functions:
Jerome Coutant 0:c0f3bbab73d2 60 - BSP_LCD_SetTransparency()
Jerome Coutant 0:c0f3bbab73d2 61 - BSP_LCD_SetLayerAddress()
Jerome Coutant 0:c0f3bbab73d2 62
Jerome Coutant 0:c0f3bbab73d2 63 + Display on LCD
Jerome Coutant 0:c0f3bbab73d2 64 o Clear the whole LCD using BSP_LCD_Clear() function or only one specified string
Jerome Coutant 0:c0f3bbab73d2 65 line using the BSP_LCD_ClearStringLine() function.
Jerome Coutant 0:c0f3bbab73d2 66 o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
Jerome Coutant 0:c0f3bbab73d2 67 function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
Jerome Coutant 0:c0f3bbab73d2 68 o Display a string line on the specified position (x,y in pixel) and align mode
Jerome Coutant 0:c0f3bbab73d2 69 using the BSP_LCD_DisplayStringAtLine() function.
Jerome Coutant 0:c0f3bbab73d2 70 o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
Jerome Coutant 0:c0f3bbab73d2 71 on LCD using the available set of functions.
