rpm chip

0 Introduction There are many types and styles for the design and development of digital voltage meters. Traditional Digital Voltage meters have their own characteristics and are suitable for manual measurement at the site, however, to complete remote measurement and further process the measurement data, the traditional digital voltmeter cannot be used. Therefore, a digital voltmeter Based on PC communication is designed in this paper. This table can transfer measurement data and process measure

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 (slave

Simple Intelligent Robot Based on AT89C51 Single-Chip Microcomputer Author: Zhang Hong, Wang dehe time: Source: Electronic EngineerBrowse comments Introduction With the continuous development of microelectronics technology, the integration of microprocessor chips is getting higher and higher, the single-chip microcomputer can integrate multiple circuits, including CPU, memory, Timer

This article is original by purplesword (jzj1993). For more information, see. Original web site http://blog.csdn.net/jzj1993 We have introduced several solutions for preparing the experiment board. Here we will first introduce solution 1. I will build a simple single-chip microcomputer lab Board together with you to enjoy hands-on practice. We have two ways to build our own lab board. One is to use a bread board, and the other is to use a universal we

Single-chip microcomputer minimum system, or the smallest application system, refers to the system which is composed of the least component and the microcontroller can work. for the 51 series microcontroller, the minimum system should generally include: single-chip microcomputer, crystal oscillator circuit, reset circuit. a minimum system circuit diagram for a 51 microcontroller is given below. Descripti

Re-install python and yum with rpm, and re-install pythonyum with rpm. The yum cannot be used for the python upgraded the other day. The prompt "No module named yum" is displayed. Then, I searched for it and said that I didn't think much about Reinstalling python and yum, I just followed the tutorials and uninstalled them, but I couldn't install them. They all followed the tutorials. As a result, there is n

use of particularly frequent and infrequent variables.In contrast, the 51-core microcontroller storage structure is a bit strange, it has 3 storage space: Program memory space (on-chip, off-chip), off-chip data memory space (64KB), on-chip data memory and special function register space. It has no real register, and i

Recently, Tsinghua Purple, Wuhan New core in the field of memory chips frequently, so that we look at the previously neglected memory chip. For a long time, in the CPU,GPU, baseband and other "advanced" chip spotlight under the cover-up, memory chip has been in obscurity, however, any one involving digital IC products, small to the bank card, big to the server, i

Introduction Flash Memory, also known as flash memory, is a new kind of non-volatile semiconductor storage developed in the late 1980s S. It has the features of Ram and Rom, which can be erased and rewritten online, and keep data intact after power loss. Nor flash is the first kind of flash memory. Compared with other types of flash memory, nor flash has the following advantages: high reliability, fast random reading speed, and single-byte or single-word programming, allows the CPU to directly r

"Introduction to the Chip" AR8033 is the 4th generation 10/100/1000mbps Rate Ethernet PHY chip of Atheros company, which can be used for home gateway, Enterprise switch, mobile base station, optical module and other equipments. The chip uses the RGMII protocol or the SGMII protocol to communicate with the MAC chip, onl
