HAL_LTDC_SetPitch() function
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().
Syntax
HAL_StatusTypeDef HAL_LTDC_SetPitch(LTDC_HandleTypeDef *hltdc,
uint32_t LinePitchInPixels,
uint32_t LayerIdx);
Implemented in ![]()
stm32f4xx_hal_ltdc.c:1411
Return value
HAL status
Notes
This function should be called only after a previous call to HAL_LTDC_ConfigLayer() to modify the default pitch configured by HAL_LTDC_ConfigLayer() when required (refer to example described just above).
