Function Documentation

◆ ifx_i2c_dl_init()

optiga_lib_status_t ifx_i2c_dl_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_ctxPointer to ifx i2c context.
[in]handlerFunction pointer to the event handler of the upper layer.
Return values
IFX_I2C_STACK_SUCCESSIf initialization was successful.
IFX_I2C_STACK_ERRORIf the module is already initialized.

◆ ifx_i2c_dl_receive_frame()

optiga_lib_status_t ifx_i2c_dl_receive_frame ( ifx_i2c_context_t p_ctx)

Function for receiving a frame.

Asynchronous function to receive a frame

  • The function returns immediately.
  • One of the following events is propagated to the event handler registered with ifx_i2c_dl_init.
Precondition
  • None
Note

Parameters
[in,out]p_ctxPointer to ifx i2c context.
Return values
IFX_I2C_STACK_SUCCESSIf function was successful.
