Serial screen (touch screen) configuration Software + 51 single-chip Modbus RTU Multi-machine serial communication program source codeRealization of the touch screen (serial screen) and SCM communication, mainly to solve the problem of communication protocols. This paper uses the open Modbus Communication protocol to Guangzhou Hmimaker touch screen as host (master), single chip microcomputer as Slave (slaver). Hmimaker touch screen itself support Modb

I am ashamed to say that I have been engaged in many things in school for a long time, but I did not seriously do the basic things of 51 single chip microcomputer. I had just learned 51 for more than a week, I switched to the 16-bit single-chip microcomputer of Apsara stack, so that 51 has not been thoroughly understood. It would be better for me to know exactly

Surrounding environment:System environment: Win7 64 positionSoftware platform: Multisim 12.0Objective:Just graduated, but the mode of knowledge also forgot almost the same, coupled with their own want to engage in hardware design. Let's say it's just a reading book. Do not practice, or eventually feel shallow. As an interest to learn the mode of electrical, simulation simulation.Multisim MCU less, take 51来 practice practiced hand. Build

51. 52 single-chip microcomputer matrix keyboard, 5152 single-chip microcomputer Matrix To learn about the matrix keyboard, first make a small experiment: After you press the matrix keyboard, the digital display displays the number of keys that are pressed. My matrix keyboard is 4x4. The operating principle is to first check which line of key is pressed. Then determine the column. In this way, you can identify which key is pressed. First, let's look a

Today, I was reading the news and found that a company has a new product, claiming that it can "directly connect to the debit card online banking to parse bills, breaking through the restrictions that can only resolve credit card bills ", every time I see a new product, I think security is the top priority! Conclusion: It is really unreliable to store financial-related information on the Internet! Today at 36kr to see the news, found 51 credit card ou

is evident in the n-queue question. Thinking of solving problems by backtracking(1) To define the solution space for the problem;(2) Determine the spatial structure of the solution that is easy to search;(3) Searching the solution space in depth first, and using pruning function to avoid invalid search during the searching process.Backtracking is to let the computer automatically to search, meet the situation to end or save, in a path to the end can not find the solution, go back to the origina

This typical C language 100 question is found online. This is also available in programming enthusiast forums. Note: I may have skipped some questions, but I have not done anything about the graphics. There are still a few questions that are not a question at all, so they are not done either.

The property object consists of the property name and value. Then, you can specify in the statement to replace the object name with the returned properties set. (Each property object contains a property name and value ). To create a properties set, enter the description. Create statement using the following syntax: SetMydescription= D

Tip 51. How to load EF metadata in any form of stream In tip 45, I showed how to generate a connection string at runtime, which is pretty nice. The problem is that it relies on metadata files (. csdl. ssdl. msl) stored on local disks. But what if these files are stored on the web server or in similar locations, and you even have no permission to access the local file system and cannot copy them to the local machine? You can also load the metadata in t
