Function Documentation

◆ ifx_i2c_tl_init()

optiga_lib_status_t ifx_i2c_tl_init	(	ifx_i2c_context_t *	p_ctx,
		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.

Precondition

This function must be called before using the module.

Note

None

Parameters

[in,out]	p_ctx	Pointer to ifx i2c context.
[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.

Here is the call graph for this function:

◆ ifx_i2c_tl_transceive()

optiga_lib_status_t ifx_i2c_tl_transceive	(	ifx_i2c_context_t *	p_ctx,
		uint8_t *	p_packet,
		uint16_t	packet_len,
		uint8_t *	p_recv_packet,
		uint16_t *	p_recv_packet_len
	)

Function to transmit 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
