Detailed Description

Function Documentation

◆ card_transceive_mode_start()

UFR_STATUS DL_API card_transceive_mode_start	(	uint8_t	tx_crc,
		uint8_t	rx_crc,
		uint32_t	rf_timeout,
		uint32_t	uart_timeout )

Function sets the parameters for transceive mode. If the hardware CRC option is used, then only command bytes are sent to the card (hardware will add two bytes of CRC to the end of the RF packet). If this option did not use, then command bytes and two bytes of CRC sent to card (i.e. ISO14443 typeA CRC). Timeout for card response in us sets. Card is selected and waiting for commands.

Parameters

tx_crc	hardware RF TX crc using (1 - yes, 0 - no
rx_crc	hardware RF RX crc using (1 - yes, 0 - no)
rf_timeout	timeout for card response in us
uart_timeout	timeout for UART response in ms

Returns: Operation status

◆ card_transceive_mode_stop()

UFR_STATUS DL_API card_transceive_mode_stop ( void )

The function returns the reader to normal mode.

Returns: Operation status

◆ card_halt_enable()

UFR_STATUS DL_API card_halt_enable ( void )

Function enables normal working mode of reader, after leaving the transceive working mode with blocking card HALT command in the main loop.

Returns: Operation status

◆ uart_transceive()

UFR_STATUS DL_API uart_transceive	(	IN uint8_t *	send_data,
		uint8_t	send_len,
		OUT uint8_t *	rcv_data,
		uint32_t	bytes_to_receive,
		VAR uint32_t *	rcv_len )

The function sends data through the serial port to the card.
