Jerome Coutant 0:146cf26a9bbb 22 User NOTES
Jerome Coutant 0:146cf26a9bbb 23 1. How To use this driver:
Jerome Coutant 0:146cf26a9bbb 24 --------------------------
Jerome Coutant 0:146cf26a9bbb 25 - This driver is used to drive directly in video mode a LCD TFT using the DSI interface.
Jerome Coutant 0:146cf26a9bbb 26 The following IPs are implied : DSI Host IP block working
Jerome Coutant 0:146cf26a9bbb 27 in conjunction to the LTDC controller.
Jerome Coutant 0:146cf26a9bbb 28 - This driver is linked by construction to LCD KoD mounted on board MB1166.
Jerome Coutant 0:146cf26a9bbb 29
Jerome Coutant 0:146cf26a9bbb 30 2. Driver description:
Jerome Coutant 0:146cf26a9bbb 31 ---------------------
Jerome Coutant 0:146cf26a9bbb 32 + Initialization steps:
Jerome Coutant 0:146cf26a9bbb 33 o Initialize the LCD using the BSP_LCD_Init() function.
Jerome Coutant 0:146cf26a9bbb 34 o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
Jerome Coutant 0:146cf26a9bbb 35 o Enable the LCD display using the BSP_LCD_DisplayOn() function.
Jerome Coutant 0:146cf26a9bbb 36
Jerome Coutant 0:146cf26a9bbb 37 + Options
Jerome Coutant 0:146cf26a9bbb 38 o Configure and enable the color keying functionality using the
Jerome Coutant 0:146cf26a9bbb 39 BSP_LCD_SetColorKeying() function.
Jerome Coutant 0:146cf26a9bbb 40 o Modify in the fly the transparency and/or the frame buffer address
Jerome Coutant 0:146cf26a9bbb 41 using the following functions:
Jerome Coutant 0:146cf26a9bbb 42 - BSP_LCD_SetTransparency()
Jerome Coutant 0:146cf26a9bbb 43 - BSP_LCD_SetLayerAddress()
Jerome Coutant 0:146cf26a9bbb 44
Jerome Coutant 0:146cf26a9bbb 45 + Display on LCD
Jerome Coutant 0:146cf26a9bbb 46 o Clear the whole LCD using BSP_LCD_Clear() function or only one specified string
Jerome Coutant 0:146cf26a9bbb 47 line using the BSP_LCD_ClearStringLine() function.
Jerome Coutant 0:146cf26a9bbb 48 o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
Jerome Coutant 0:146cf26a9bbb 49 function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
Jerome Coutant 0:146cf26a9bbb 50 o Display a string line on the specified position (x,y in pixel) and align mode
Jerome Coutant 0:146cf26a9bbb 51 using the BSP_LCD_DisplayStringAtLine() function.
Jerome Coutant 0:146cf26a9bbb 52 o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
Jerome Coutant 0:146cf26a9bbb 53 on LCD using the available set of functions.
