HAL_LTDC_SetAlpha() function

pointer to a LTDC_HandleTypeDef structure that contains the configuration information for the LTDC.

new alpha value.

LTDC Layer index. This parameter can be one of the following values: LTDC_LAYER_1 (0) or LTDC_LAYER_2 (1)

Handle LTDC interrupt request.

Set the LTDC window position.

Configure the LTDC Layer according to the specified parameters in the LTDC_InitTypeDef and create the associated handle.

Initialize the LTDC according to the specified parameters in the LTDC_InitTypeDef.

Enable the color lookup table.

Load the color lookup table.

De-initialize the LTDC peripheral.

Define the position of the line interrupt.

Reconfigure the frame buffer Address.

Enable the color keying.

Disable the color keying.

Configure the color keying.

Initialize the LTDC MSP.

De-initialize the LTDC MSP.

Function used to reconfigure the pitch for specific cases where the attached LayerIdx buffer have a width that is larger than the one intended to be displayed on screen. Example of a buffer 800x480 attached to layer for which we want to read and display on screen only a portion 320x240 taken in the center of the buffer. The pitch in pixels will be in that case 800 pixels and not 320 pixels as initially configured by previous call to HAL_LTDC_ConfigLayer().
