What does a single-chip microcomputer support ISP programming?

1. Programming in the system. Single-chip microcomputer ISP refers to InSystemProgramming, that is, programming in the system. It is a single-chip microcomputer burning method that can be programmed without removing the chip. Through the ISP interface line, the program can be written directly to the internal memory of the single-chip microcomputer without having to remove the chip from the circuit board.

2. ISP (online system programming) is when the system is powered on and working normally.At that time, the computer directly programs it through the ISP owned by the CPLD in the system, and the device enters the normal working state immediately after programming. The emergence of this CPLD programming method has changed many inconveniences of the traditional use of dedicated programmer programming methods.

3. isp: single-chip microcomputer ISP, that is, In-System Programming, online programming. Single-chip microcomputer chips with ISP function can write or erase programs directly to the chip on the circuit board through a simple download line, and support online debugging.

4. ISP is actually online programming. In the past, single-chip microcomputer download programs needed burners and so on, and the single-chip microcomputer needed to be unplugged from the circuit board and burned, and then plugged in, which was very troublesome.

5. ISP is the English abbreviation of In system programming. It means online burning.

6. ISP, that is, In-SystemProgramming, online programming. Single-chip microcomputer chips with ISP function can write or erase programs directly to the chip on the circuit board through a simple download line, and support online debugging.

What is programmable in the system?

In system programming: ISP (In-System Programming) is programmable in the system, which means that the blank devices on the circuit board can be programmed and written to the end-user code without the need to remove the device from the circuit board, and the programmed devices can also be used with ISP. Erase or reprogram in the way.ISP technology is the future development direction.

Expandability Object-oriented programming essentially supports scalability. If there is a class with a certain function, you can quickly expand the class and create a class with an extended function.

System programming is for some development of the system, such as managing a library system, etc. System programming needs to combine the relevant algorithms of database and data structure to achieve the effect of the program. For example, C++ language is suitable for system development. There is also the development of hardware drivers, which is also related to system programming.

Programmable refers to a method that can program, customize or modify certain objects or technologies to meet different needs. For example, in the field of industrial robots, programming software can be used to program the robot to achieve different operations;In the field of computer software, programmers can use programming languages to write programs to achieve different functions.

System programming and IAP technology

MCU programmable IAP (In-Applicat Ion Programming) in application programming, refers to MCU can get new code in the system and reprogram itself, and then use the program to change the program.

IAP is the initials of InApplicationProgramming. IAP is the user's own program that burns part of the area of UserFlash during operation. The purpose is to conveniently pass the reservation after the product is released. The communication port updates and upgrades the firmware program in the product.

isp is a system programming technology, which refers to the burning program to the single-chip microcomputer. The burning program can be completed by removing the chip from the circuit board. Iap is application programming, which refers to the program modification and burning of a single-chip computer in the process of power-on work, just like installing applications without shutting down the mobile phone.

What is the programmable technology in the system? What are its characteristics

At present, the programmable technology widely used in the system of EDA technology is generated to overcome this shortcoming. The so-called in-system configurability means that programmable logic devices have the ability to provide in-system programmability for designers, but also have the ability to program and reprogram devices by plugging devices into the system or circuit boards.

In system programming: ISP (In-System Programming) can be programmed in the system, which means that the blank devices on the circuit board can be programmed and written to the end-user code without the need to remove the devices from the circuit board. The programmed devices can also be used by ISP. Erase or reprogram. ISP technology is the future development direction.

ISP generally programs the Flash memory inside the single-chip microcomputer through the serial programming interface dedicated to the single-chip microcomputer. IAP technology maps the Flash memory into two memory bodies from the structure. When running the user program on one memory body, it can New programming, and then the control will be transferred from one storage to another.

Management and maintenance: The program can automatically complete reminders, adjustments, updates and other functions, which is of great help to daily management and maintenance. In general, programming is one of the indispensable technologies in today's era. It can help us better understand and utilize digital information, improve work efficiency, and create more value.

Share high-quality videos of automation and explain automation knowledge from shallow to deep.

Why many programmers like to program in the Linux system

1. It provides rich network functions: a perfect built-in network is a major feature of Linux. Reliable security system: Linux has taken many security technical measures, including read and write control, protected subsystems, audit tracking, kernel authorization, etc., which provides necessary security protection for users in network multi-user environments.

2. Linux and windows are two different operating systems. Different operating systems have different compilation environments, so the knowledge is different. Because linux is open source, it is free, so some companies use linux, which can save costs, of course. , this knowledge is one of the advantages of Linux.

3. It is said that Linux is powerful because Linux is open source. As a programmer, I like Linux because of the simple essence of the Linux kernel. Open source can read the source code, so that you know what your OS is doing, and Linux is very stable. As a programmer, you can learn To a lot of things.

4. Therefore, it is based on the openness of the source code of the Linux system, which allows many programmers to have the opportunity to learn and avoid making mistakes. Moreover, the Linux system is safe to use, and can be operated by multiple different users and multiple tasks, which can also better meet the needs of programmers. , that's why it is more and more popular with IT personnel.

What is the main application scope of the programmable controller?

1. This function has been widely used in boilers, reactors, water treatment, brewing, closed-loop position control and speed control.

2. Programmable controller (PLC) is a digital computing device used for automated control systems, which is used to control mechanical or electrical equipment in the production process. PLC completes the control of the production process by collecting, processing and outputting input signals.

3. Switching quantity logic control uses the most basic logic operation, timing, counting and other functions of PLC to realize logic control, which can replace the traditional relay control and is used for stand-alone control, multi-machine group control, production automatic line control, etc., such as: machine tools, injection molding machines, printing machinery, assembly production lines , electroplating assembly line and elevator control, etc.

4. The programmable controller is modularized by internal CPU, instruction and data memory, input and output units, power modules, digital analog and other units. Application: It is widely used in the current industrial control field.
