ATmega single-chip microcomputer program network remote upgrading method and system thereof

Abstract

The invention discloses an ATmega single-chip microcomputer program network remote upgrading method and a system thereof. The system comprises a starting module, three judging modules and three corresponding executing modules. The starting module is used for starting an ATmega single-chip microcomputer, the judging modules are used for judging received PC end commands, and the different PC end commands are executed through the corresponding executing modules. According to the ATmega single-chip microcomputer program network remote upgrading method and the system thereof, the functions of software coding, upgrading, data verifying and the like are achieved through network interfaces of the system according to the received PC end commands, and the coding mode is easier, more convenient to implement and more reliable compared with a traditional coding mode.

Description

technical field [0001] The inventive method relates to computer information processing and ATmega single-chip microcomputer code writing technology, particularly a kind of machine code file of HEX format is transmitted to ATmega single-chip microcomputer (hereinafter referred to as single-chip microcomputer) through network communication interface, and application IAP technology is written into single-chip computer by machine code program On-chip Flash method. Background technique [0002] ATmega is a new AVR high-end single-chip microcomputer launched by ATMEL company. It has more interface functions, and is more comprehensive and perfect in terms of power saving performance, stability, anti-interference and flexibility. This single-chip microcomputer is widely used in various electronic products. middle. For program downloading, the traditional method is to first connect the ATmega microcontroller through a dedicated download line, and then write the HEX machine code prog...

AI Technical Summary

Problems solved by technology

Defects or insufficiencies of the traditional method: because each time the code is written, the power of the machine is first judged, and a dedicated download line is used to connect the PC and the single-chip microcomputer for downloading operations. After the download is completed, remove the download line and restart the single-chip computer to run the newly downloaded program normally. , this method is inefficient, the operation method is complicated, a special download tool is required, and remote download cannot be realized.
