Function Documentation

◆ HAL_LTDCEx_StructInitFromVideoConfig()

HAL_StatusTypeDef HAL_LTDCEx_StructInitFromVideoConfig	(	LTDC_HandleTypeDef *	hltdc,
		DSI_VidCfgTypeDef *	VidCfg )

#include <stm32f4xx_hal_ltdc_ex.h>

Retrieve common parameters from DSI Video mode configuration structure.

Parameters

hltdc	pointer to a LTDC_HandleTypeDef structure that contains the configuration information for the LTDC.
VidCfg	pointer to a DSI_VidCfgTypeDef structure that contains the DSI video mode configuration parameters

Note: The implementation of this function is taking into account the LTDC polarities inversion as described in the current LTDC specification

Return values

HAL status
