+## 3.13 AIN 电流电压测试
+
+### 3.13.1 硬件原理图说明
+
+
+
+
+
+### 3.13.2 AIN 电流测试
+
+首先我们需要将ADC采样程序烧录到开发板上的单片机中
+
+连接J6000 TTL下载调试串口 Debug_RXD_CN连接串口的TXD Debug_TXD_CN连接串口的RXD GND相连
+
+
+
+
+
+
+
+**打开FlyMcu.exe烧录工具，选择准备好的.hex 的单片机程序**
+
+
+
+
+
+**点击开始编程后就开始烧录程序，烧录成功如下图，并且可以看到单片机的LED灯在闪烁绿光**
+
+
+
+
+
+单片机程序烧录好后，我们需要使能RK3568的UART6，根据原理图可以看到，RK3568和MCU通信串口为UART6，所以需要在设备树中设置UART6设备节点
+
+打开`~/rk3568/sdkv1.4.0_linux5.10/kernel/arch/arm64/boot/dts/rockchip/rk3568-evb1-ddr4-v10-linux.dts`
+
+加入URAT6节点
+
+```
+&uart6{
+ dma-names = "tx", "rx";
+ pinctrl-names = "default";
+ pinctrl-0 = <&uart6m1_xfer>;
+ status = "okay";
+};
+```
+
+
+
+重新编译设备树后烧录到开发板中启动开发板，在/dev下看看是否有ttyS6
+
+
+
+
+
+
+
+
+
+按照上图连接电路后，用XCOM软件打开单片机的调试串口，配置如下图所示
+
+
+
+
+
+在RK3568上运行comport程序，此程序可以配置串口的波特率，停止位，数据位，奇偶校验以及指定使用哪个串口设备
+
+源代码在[framwork.git - Gitblit (iot-yun.club)](http://main.iot-yun.club:8088/tree/framwork.git/master/booster)
+
+但是这个代码需要做一定的修改，因为这个程序只能让串口输出字符串数据，但是我们在测试中需要发送十六进制数据给单片机。
+
+
+
+此时就需要了解ADC串口协议，RK3568发送读指令给MCU，MCU会响应RK3568返回ADC采样数据
+
+
+
+示例如下：
+
+示例：
+
+1、读第0通道电压：
+
+AA 55 02 00 30 8C //CRC：0x8C30
+
+AA 55 02 00 EE 0D 99 C0 //0D EE -> 3566mv, CRC:0x0C99
+
+2、读第1路通道电压：
+
+AA 55 02 01 F1 4C
+
+AA 55 02 01 06 00 47 C5 //00 06 -> 6mv
+
+3、读第2路通道电压：
+
+AA 55 02 02 B1 4D
+
+AA 55 02 02 06 00 B7 C5 //6mv
+
+4、读第3路通道电压：
+
+AA 55 02 03 70 8D
+
+AA 55 02 03 06 00 E6 05 //6mv
+
+5、读第0路电流
+
+AA 55 01 00 30 7C
+
+AA 55 01 00 95 01 BB 71 //01 95 -> 405 单位0.01mA,即4.05mA， CRC:0x71BB
+
+6、读第1路电流
+
+AA 55 01 01 F1 BC
+
+AA 55 01 01 95 01 EA B1
+
+7、读第2路电流
+
+AA 55 01 02 B1 BD
+
+AA 55 01 02 95 01 1A B1
+
+8、读第3路电流
+
+AA 55 01 03 70 7D
+
+AA 55 01 03 95 01 4B 71
+
+
+
+以下AIN电流测试以测试第0路电流为例
+
+在RK3568上输入`./comport -d /dev/ttyS6 -b 115200 -s 8N1N -x`
+
+在XCOM上可以看到MCU的调试信息，旋转电位器旋钮至最左或最右分别测量最小电流和最大电流，量程约为1.22mA~22.79mA(测试其他三路电流时最小电流约为0.006mA)
+
+
+
+
+
+### 3.12.3 AIN 电压测试
+
+准备工作和AIN电流测试一样，不再赘述
+
+
+
+运行comport程序让rk3568输出读取电压的指令给mcu
+
+同样在XCOM上也能看到MCU的采样调试信息，旋转电位器旋钮至最左或最右分别测量最小电流和最大电流，量程约为0.017mV~5.882mV
