Detailed Description

Module for the transport layer of the Infineon I2C Protocol Stack library.

Function Documentation

uint16_t ifx_i2c_tl_init

(

ifx_i2c_event_handler_t

handler

)

Function for initializing the module.

Function initializes and enables the module and registers an event handler to receive events from this module.

Attention

This function must be called before using the module.

Parameters

[in]

handler

Function pointer to the event handler of the upper layer.

Return values

IFX_I2C_STACK_SUCCESS	If initialization was successful.
IFX_I2C_STACK_ERROR	If the module is already initialized.

uint16_t ifx_i2c_tl_transceive	(	uint8_t *	packet,
		uint16_t	packet_len
	)

Function to transmit and receive a packet.

Asynchronous function to send and receive a packet. The function returns immediately. One of the following events is propagated to the event handler registered with ifx_i2c_tl_init

Parameters

[in]	packet	Buffer containing the packet.
[in]	packet_len	Frame length.

Return values

IFX_I2C_STACK_SUCCESS	If function was successful.
IFX_I2C_STACK_ERROR	If the module is busy.
