提高CLRC663非接读卡器读通行证的速度

[elvyis]

       你好，我现在在想提高RC663非接读卡器读通行证读写的速度，打算从106kbit/s提高到424kbit/s,目前调试的是14443的B卡，我尝试修改wRc663_DefaultShadow_I14443b如下图，但是修改后调用初始化寻卡选卡读uid，但是返回Sw= 0x6c06，请问还需要改动哪里才能正常提速？先谢谢各位大佬！！用的是Nxp663RdLib！

       Default shadow for ISO14443-3B Mode：

static const uint16_t PH_MEMLOC_CONST_ROM wRc663_DefaultShadow_I14443b[][2] =
{
    {PHHAL_HW_CONFIG_PARITY,                PH_OFF},
    {PHHAL_HW_CONFIG_TXCRC,                 PH_ON},
    {PHHAL_HW_CONFIG_RXCRC,                 PH_ON},
    {PHHAL_HW_CONFIG_RXDEAFBITS,            0x0008},
    {PHHAL_HW_CONFIG_TXWAIT_US,             85},
    #if 0 
    {PHHAL_HW_CONFIG_TXDATARATE,            PHHAL_HW_RF_DATARATE_106},
    {PHHAL_HW_CONFIG_RXDATARATE,            PHHAL_HW_RF_DATARATE_106},
 #else
 {PHHAL_HW_CONFIG_TXDATARATE,   PHHAL_HW_RF_DATARATE_424},
 {PHHAL_HW_CONFIG_RXDATARATE,      PHHAL_HW_RF_DATARATE_424},
 #endif
 {PHHAL_HW_CONFIG_TIMEOUT_VALUE_US,      PHHAL_HW_RC663_DEFAULT_TIMEOUT},
    {PHHAL_HW_CONFIG_TIMEOUT_VALUE_MS,      0x0000},
    {PHHAL_HW_CONFIG_MODINDEX,              PHHAL_HW_RC663_MODINDEX_I14443B},
    {PHHAL_HW_CONFIG_ASK100,                PH_OFF}
};

你用的是最新版的NFC reader library吗？type B默认都是从106K开始通信的，如果你的应用是基于最新的NFC reader library的话，在通信过程中会根据PICC的应答设置成该卡支持的最大数据传输率，无需做上述的改动。

Have a great day,
