If you send this article, you should leave a small souvenir; If there is anything bad, please point out   the code of Keil C51 and the simulated Baidu network disk link of Proteus are put here   link: Point me jump point me point me poi ...

Customize one master multi slave serial communication_ one This is a small record similar to the development log. This article mainly records a communication protocol based on serial communication customized in Bi Shuli. As for why I didn't use modbus, it's just because I didn't use it. Hardware foundation In general, there are three mai ...

HC-05 Bluetooth serial communication HC05 module is a high-performance master-slave Bluetooth serial port module. It is a PCBA board integrating Bluetooth function. It is very convenient for short-range wireless communication. It can be seen from a treasure merchant that Bluetooth can be used in many ways. Here I use Bluetooth host connection ...

1, Brief introduction of theoretical knowledge 1. Serial communication protocol and RS-232 standard (1) Brief description of serial communication protocol Serial communication refers to sending and receiving bytes by bit. Although the serial communication of bits and bytes is slow, the serial port can use one line to send data and anothe ...

Understand I2C bus protocol What is the I2C protocol? The I2C communication protocol (Inter Integrated Circuit) is composed of Phiilps Developed by the company, because it has few pins, simple hardware implementation and strong scalability, it does not need USART and CAN And other communication protocols are now widely used in the communic ...

Blue Bridge Cup MCU preliminary code basic framework preface The preliminary competition of Blue Bridge Cup single chip microcomputer gives me the feeling that on the basis of being familiar with the basic modules, combining the basic modules, and using interrupt and timer assistance at the same time, I can complete most functions.
