Module for the data link layer of the Infineon I2C Protocol Stack library.
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. |

|
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.
- Return values
-
| IFX_I2C_STACK_SUCCESS | If function was successful. |
| IFX_I2C_STACK_ERROR | If the module is busy. |

Function for sending a frame.
Asynchronous function to send a frame. The function returns immediately. One of the following events is propagated to the event handler registered with ifx_i2c_dl_init.
- Parameters
-
| [in] | frame | Buffer containing the frame. |
| [in] | frame_len | Frame length. |
- Return values
-
| IFX_I2C_STACK_SUCCESS | If function was successful. |
| IFX_I2C_STACK_ERROR | If the module is busy. |
