PN7120读卡等待时间是否能够调整?

Dear All:

   我使用PN7120做读卡器,卡放在读卡器上,从发送读卡指令到读到数据大概要1s多的时间,请问这是否正常?

   使用官方示例程序“NXP-NCI_LPC82X_example”用开发板测试,等待时间也差不多,请问是否可以通过设置参数调整该时间?

   谢谢!

Hi,

You may change the TOTAL_DURATION of the discovery period to check if it makes any difference.

The default value is 0x0100, you may change it to lower value.

Hope that helps,


Have a great day,
Kan

Hi Kan

   非常感谢你的回答。

   根据上面的方法进行测试,效果不太明显。修改为0x0080和0x0030等待时间减少的都非常少,不太能够感觉出来。
