How to interconnect single-chip serial communication rxd with txd Category:8051 2012-04-0711: 35 Read by 348 Comment (0) Favorites Report Reprinted from: http://blog.csdn.net/sdwuyulunbi/article/details/6632382 I believe many people are confused about how to connect rxd and txd when the microcontroller communicates with a computer or chip. In some circuit diagrams, some are the direct connection method and some are the

equipment) or a data terminal device-dte (the information Terminal equipment). The difference between them is very simple, each signal pair, such as transmission and reception, they are exactly the opposite. If you need to connect two DTE or DCE devices, you need an adapter or crossover cable to swap the signal pair. ↑ What is rs-232†RS-232 is an electrical interface for

Introduction to serial programming in Linux-general Linux technology-Linux programming and kernel information. For more information, see below. Introduction: The Linux operating system has provided good support for the serial port from the very beginning. This article briefly introduces the serial port communication programming in Linux.

The serial cable can be divided into straight chain and intersection. Generally for straight line extension PC equip, will 2, 3, 5 connect 2, 3, 5, because PC universal male. But the devices are mostly female, so they are just plain, and it can also be used to extend the connection; the crossover PC is connected to the PC with 2 pairs of 3, 3 pairs of 2, 5 to 5, and the general two are female at both ends!Before the computer appeared, the EIA establis

On a blog analysis of the serial drive initialization section, the following step-by-step analysis of serial port drive in the open serial, data transmission and reception.

The serial line also points through and crosses, pass-through is generally used to extend the PC and equipment, will be 2, 3, 5 respectively connected 2, 3, 5, because the PC is generally male, and the device is mostly female, so just they are universal, can be used for extension can also be used for connection; crossover is generally used for PC docking with PC, 2 to 3, 3 to 2, 5 to 5, usually both ends are female!Before the computer appeared, the EI

Serial Port is also called "Serial Port". It is mainly used for serial data transmission. Common RS-232 with general computer applications (using 25-pin or 9-pin connectors) and half duplex RS-485 for industrial computer applications with full duplex RS-422. Serial interface according to electrical standards and proto
