HAL_FMPSMBUS_IsDeviceReady()

HAL_StatusTypeDef HAL_FMPSMBUS_IsDeviceReady	(	FMPSMBUS_HandleTypeDef *	hfmpsmbus,
		uint16_t	DevAddress,
		uint32_t	Trials,
		uint32_t	Timeout )

#include <stm32f4xx_hal_fmpsmbus.h>

Check if target device is ready for communication.

Parameters

hfmpsmbus	Pointer to a FMPSMBUS_HandleTypeDef structure that contains the configuration information for the specified FMPSMBUS.
DevAddress	Target device address: The device 7 bits address value in datasheet must be shifted to the left before calling the interface
Trials	Number of trials
Timeout	Timeout duration
