The SmartCard EMVSIM driver covers the transmission functionality in the CPU mode. The driver supports non-blocking (asynchronous) type of data transfers. The blocking (synchronous) transfer is supported only by the RTOS adaptation layer.

When performing an async transfer, call this function to ascertain the context of the current transfer: in progress (or busy) or complete (success). If the transfer is still in progress, the user can obtain the number of words that have not been transferred.
- Parameters
-
base | The EMVSIM module base address. |
context | A pointer to a smart card driver context structure. |
- Returns
- The number of bytes not transferred.
During an async EMVSIM transfer, the user can terminate the transfer early if the transfer is still in progress.
- Parameters
-
base | The EMVSIM peripheral address. |
context | A pointer to a smart card driver context structure. |
- Return values
-
kStatus_SMARTCARD_Success | The transmit abort was successful. |
kStatus_SMARTCARD_NoTransmitInProgress | No transmission is currently in progress. |
A non-blocking (also known as asynchronous) function means that the function returns immediately after initiating the transfer function. The application has to get the transfer status to see when the transfer is complete. In other words, after calling non-blocking (asynchronous) transfer function, the application must get the transfer status to check if transmit is completed or not.
- Parameters
-
base | The EMVSIM peripheral base address. |
context | A pointer to a smart card driver context structure. |
xfer | A pointer to smart card transfer structure where are linked buffers and sizes. |
- Returns
- An error code or kStatus_SMARTCARD_Success.
- Parameters
-
base | The EMVSIM peripheral base address. |
context | A pointer to a smart card driver context structure. |
control | Control type |
param | Integer value of specific to control command. |
return kStatus_SMARTCARD_Success in success. return kStatus_SMARTCARD_OtherError in case of error.
- Parameters
-
base | The EMVSIM peripheral base address. |
context | A pointer to a smart card driver context structure. |
