Function Documentation

HAL_StatusTypeDef HAL_LTDCEx_StructInitFromAdaptedCommandConfig	(	LTDC_HandleTypeDef *	hltdc,
		DSI_CmdCfgTypeDef *	CmdCfg
	)

Retrieve common parameters from DSI Adapted command mode configuration structure.

Parameters:

hltdc	pointer to a LTDC_HandleTypeDef structure that contains the configuration information for the LTDC.
CmdCfg	pointer to a DSI_CmdCfgTypeDef structure that contains the DSI command 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
