使用教程：8x16模拟开关阵列可级联XY脚双向导通自动化接线
以下通过点亮LED进行基本使用流程演示，实际可以连接复杂外设（SPI、CAN、ADC等）
- 单模块使用
- RX、TX、5V和GND接到串口模块；X5接5V；Y2接LED+;LED-接GND
串口模块插上电脑后，LED没有亮；因为此时模拟开关所有节点都为断开状态
| X0 | X1 | X2 | X3 | X4 | X5 | X6 | X7 | X8 | X9 | XA | XB | XC | XD | XE | XF | |
| Y0 | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF | OFF |

- 电脑浏览器打开webuart.com在线串口调试工具（或其他串口上位机软件），波特率9600
- 先获取本设备的ID，串口发送{c:id}
可知本模块唯一物理ID为35167dbe
（所有指令的用法在文档末尾）
- 让模块打开LED，即将X5与Y2接通；串口发送{id:35167dbe,c:config,x:5,y:2,enable:1}
发送串口指令后，串口返回OK字符
此时X5和Y2引脚导通，LED成功点亮

- 多模块级联
- 硬件接线
模块一：RX、TX、5V和GND接到串口模块；Y2接LED+;LED-接GND；X0~7接模块二Y0~7
模块二：X0接5V
- 导通LED
已知模块一编号为35167dbe、模块二编号为37167dbe
要让导通LED，路径可以选择“模块一的Y2、X5导通”且“模块二的Y5、X0导通”
串口连续发送指令：
{id:35167dbe,c:config,x:5,y:2,enable:1}
{id:37167dbe,c:config,x:0,y:5,enable:1}
发送串口指令后，两个模块串口均返回OK字符
LED成功点亮
