This command sends a data stream to a card and returns the communication status and the received card data stream to the host.
- Parameters
-
| [in] | params | Struct with the following fields:
- protocol used to execute the command
- EnCRCRX (in) Enable CRC check over received data.
- EnCRCTX (in) Enable CRC over transmitted data.
- SendDataLen (in) Number of bytes to send.
- Timeout (in) Timeout in ms between sending the last bit to the card and receiving the first bit from the card.
- DSI (in) Divisor Send/Receive Integer (DSI/DRI) This parameter is mapped to the Divisor Send/Receive (DS/DI) value, which determines bit rate for sending data from PICC to PCD. The possible DS/DR values (mapped to the DSI/DRI index) are listed below.
- DRI (in) Divisor Send/Receive Integer (DSI/DRI) This parameter is mapped to the Divisor Send/Receive (DS/DI) value, which determines bit rate for sending data from PICC to PCD. The possible DS/DR values (mapped to the DSI/DRI index) are listed below.
- SendData (in) Data to transmit. Bits will always be transferred LSB first.
- SendData_len (in) Length of SendData (in bytes).
- RecvData (out) Returned data.
- RecvData_len (out) Length of RecvData (in bytes).
- mempool (in) is used to store response data. Maybe NULL to use an internal mempool, in this case the data is only available until another command uses the internal mempool
