Hi All,

I am trying to read the UID from ISO15693 card from LEGIC. However, the card is not responding to the inventory command.

Can someone please check if the register settings are correct and if my INVENTORY command is OK?

[0x10] REG_PAGE2
[0x11] REG_TX_CONTROL 0x5B
[0x12] REG_CW_CONDUCTANCE 0x3F
[0x13] REG_MOD_CONDUCTANCE 0x05
[0x14] REG_CODER_CONTROL 0x2F
[0x15] REG_MOD_WIDTH 0x3F
[0x16] REG_PRESET_16 0x3F
[0x17] REG_TYPE_B_FRAMING 0x00

[0x18] REG_PAGE3
[0x19] REG_RX_CONTROL1 0x8B
[0x1A] REG_DECODER_CONTROL 0x34
[0x1B] REG_BIT_PHASE 0x54
[0x1C] REG_RX_THRESHOLD 0x68
[0x1D] REG_BPSK_DEM_CONTROL 0x00
[0x1E] REG_RX_CONTROL2 0x01
[0x1F] REG_CLOCK_Q_CONTROL 0x07

[0x20] REG_PAGE4
[0x21] REG_RX_WAIT 0x08
[0x22] REG_CHANNEL_REDUNDANCY0x2C
[0x23] REG_CRC_PRESET_LSB 0xFF
[0x24] REG_CRC_PRESET_MSB 0xFF
[0x25] REG_PRESET_25 0x00
[0x26] REG_MFOUT_SELECT 0x00
[0x27] REG_PRESET_27 0x00

I send the inventory command as below:
(Only one card is presented in the filed therfore anticollsion ignored..)

Total 3 bytes excluding CRC
BYTE0: FLAGS = H’27 => sub-carriers_flag = 1, data_rate_flag = 1, inventory_flag =, Nb_slots_flag= 1
BYTE1: INVENTORY CMD = H’01
BYTE2: MASK LEN = H’0

CRC values sent by RC632!
Any help will be highly appreciated. Thanks in advance.
