| 17 | ##### How to use this driver #####
|
---|
| 18 | ==============================================================================
|
---|
| 19 | [..]
|
---|
| 20 | (#) Program the required configuration through the following parameters:
|
---|
| 21 | the LTDC timing, the horizontal and vertical polarity,
|
---|
| 22 | the pixel clock polarity, Data Enable polarity and the LTDC background color value
|
---|
| 23 | using HAL_LTDC_Init() function
|
---|
| 24 |
|
---|
| 25 | (#) Program the required configuration through the following parameters:
|
---|
| 26 | the pixel format, the blending factors, input alpha value, the window size
|
---|
| 27 | and the image size using HAL_LTDC_ConfigLayer() function for foreground
|
---|
| 28 | or/and background layer.
|
---|
| 29 |
|
---|
| 30 | (#) Optionally, configure and enable the CLUT using HAL_LTDC_ConfigCLUT() and
|
---|
| 31 | HAL_LTDC_EnableCLUT functions.
|
---|
| 32 |
|
---|
| 33 | (#) Optionally, enable the Dither using HAL_LTDC_EnableDither().
|
---|
| 34 |
|
---|
| 35 | (#) Optionally, configure and enable the Color keying using HAL_LTDC_ConfigColorKeying()
|
---|
| 36 | and HAL_LTDC_EnableColorKeying functions.
|
---|
| 37 |
|
---|
| 38 | (#) Optionally, configure LineInterrupt using HAL_LTDC_ProgramLineEvent()
|
---|
| 39 | function
|
---|
| 40 |
|
---|
| 41 | (#) If needed, reconfigure and change the pixel format value, the alpha value
|
---|
| 42 | value, the window size, the window position and the layer start address
|
---|
| 43 | for foreground or/and background layer using respectively the following
|
---|
| 44 | functions: HAL_LTDC_SetPixelFormat(), HAL_LTDC_SetAlpha(), HAL_LTDC_SetWindowSize(),
|
---|
| 45 | HAL_LTDC_SetWindowPosition(), HAL_LTDC_SetAddress.
|
---|
| 46 |
|
---|
| 47 | (#) To control LTDC state you can use the following function: HAL_LTDC_GetState()
