# 超高频（UHF） RFID 卡读写的 Cordova 插件
## 说明
**使用UHF1_Com13_SDK_v1.5，针对k71v1_64_bsp型号设备**
## 安装
使用 Cordova
<pre>cordova plugin add https://github.com/shuto-cn/UHF#Com13_SDK_v1.5</pre>
使用 Ionic
<pre>ionic cordova plugin add https://github.com/shuto-cn/UHF#Com13_SDK_v1.5</pre>
## 示例程序
https://github.com/shuto-cn/uhf-demo/tree/Com13_SDK_v1.5
## 目前提供的功能
### 单次询卡 - 读取卡的 EPC
* 调用：
<pre>cordova.plugins.uhf.searchCard(successCallBack, errorCallback);</pre>
* 参数：
* 返回值：
EPC数组，因为可能读到多个。<pre>["30396062C3AE88C00021E2BC"]</pre>
* 多次巡卡方法已取消，如有需求请用js实现。
### 写卡
* 调用：
<pre>cordova.plugins.uhf.writeCard(message, successCallBack, errorCallback);</pre>
* 参数：
<pre>
{
data: "内容"
}
</pre>
* 内容为需要写入user区的数据，支持中英文，上限为128位16进制
* 返回值：“写入成功”或“写入失败”
### 读卡
* 仅读取user区的内容
* 调用：
<pre>cordova.plugins.uhf.readCard(successCallBack, errorCallback);</pre>
* 返回值：
<pre>"内容"</pre>
### 设置功率
* 调用：
<pre>cordova.plugins.uhf.setPower(power, successCallBack, errorCallback);</pre>
* 参数：
<pre>
目前支持的功率值为 16 至 26，超出范围会按最大或最小值处理。
</pre>
* 返回值：“设置成功”或“设置失败”
