威纶触摸屏通过MODBUS协议，可以与单片机自由通信。我通过串口调试助手，测试了威纶触摸屏不同元件时，查询和响应的数据，对于与单片机通信具有指导意义。串口是RS232接口！

MODBUS is an application layer messaging protocol, positioned at level 7 of the OSI model,which provides client/server communication between devices connected on different types of buses or networks.
The industry’s serial de facto standard since 1979, MODBUS continues to enable millions of automation devices to communicate.
Today, support for the simple and elegant structure of MODBUS continues to grow. The Internet community can access MODBUS at a reserved system port 502 on the TCP/IP stack.
MODBUS is a request/reply protocol and offers services specified by function codes.MODBUS function codes are elements of MODBUS request/reply PDUs. The objective of this document is to describe the function codes used within the framework of MODBUS transactions.
