Detailed Description

Function Documentation

card_transceive_mode_startM()

UFR_STATUS DL_API card_transceive_mode_startM	(	UFR_HANDLE	hndUFR,
		uint8_t	tx_crc,
		uint8_t	rx_crc,
		uint32_t	rf_timeout,
		uint32_t	uart_timeout )

Multi reader support. 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

hndUFR	handle of the uFR device
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_stopM()

UFR_STATUS DL_API card_transceive_mode_stopM

(

UFR_HANDLE

hndUFR

)

Multi reader support. The function returns the reader to normal mode.

Parameters

hndUFR

handle of the uFR device

Returns

Operation status

card_halt_enableM()

UFR_STATUS DL_API card_halt_enableM

(

UFR_HANDLE

hndUFR

)

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

Parameters

hndUFR

handle of the uFR device

Returns

Operation status

uart_transceiveM()

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

Multi reader support. The function sends data through the serial port to the card.

Parameters

hndUFR	handle of the uFR device
send_data	pointer to data array for sending to card
send_len	number of bytes for sending
rcv_data	pointer to data array received from card
bytes_to_receive	expected number of bytes received from card
rcv_len	number of bytes received from card

Returns

Operation status
