#The Fifth Lichuang Electronic Design Competition#MODBUS data monitor

* 1. Self/Team Introduction
Graduated from the School of Information Technology of Guilin University of Electronic Science and Technology. I have participated in two mathematical modeling competitions (second and third prizes in Guangxi District) and College Student Electronic Design Competition (second prize in the country and first prize in Guangxi District). Award), the things I make after work are too simple, not challenging, and not fun. I want to do something fun, something that makes me feel cool!

* 2. Briefly introduce the project.
Modbus protocol is often used in work. I often need to turn on the computer to open modbus poll to monitor or set parameters in the device operating environment. Moreover, there is no function to draw curves. If you want to look at a certain sensor or the like When a numerical change occurs, you often have to rely on your own intuition about the data to determine whether it is an outlier.
Based on these pain points, the project aims to achieve the following functions:
1. The target modbus physical address, register address, sampling interval and other parameters can be set by pressing the button;
2. The sampling curve can be displayed, and the data can be saved to FLASH, and can be extracted and generated by the host computer to generate EXCEL Document;
3. Easy to operate, the module is small enough, easy to wire, and has a USB interface (CH340) to communicate with the computer for advanced operations;
