lcrc663 读取身份证UID失败

[臣柱宣]

我用贵公司的lcrc663读取UID，发送REQB 0x05 0x00 0x00后

却收到了

[ 364.072169] fifo buf[0] = 50
[ 364.075174] fifo buf[1] = 00
[ 364.078118] fifo buf[2] = 00
[ 364.081060] fifo buf[3] = 00
[ 364.084024] fifo buf[4] = 00
[ 364.087021] fifo buf[5] = D1
[ 364.089962] fifo buf[6] = 03
[ 364.092914] fifo buf[7] = 00
[ 364.095857] fifo buf[8] = 81
[ 364.098853] fifo buf[9] = 00
[ 364.101807] fifo buf[10] = 70
[ 364.104836] fifo buf[11] = 90
[ 364.107866] fifo buf[12] = 84

13个byte的应答，但是标准的应答应该是12个byte（不包含crc byte）的

我的寄存器配置如下

会不会是你的代码问题？我们提供了REQB的脚本，你可以参考一下：https://www.nxp.com/downloads/en/software/210910.zip?fsrch=1&sr=1&pageNum=1 。解压之后找到RC663_ISO14443B_ReqB.jcf。

Have a great day,
Kan
