Embodiment 1

[0022] The invention provides a method for online programming and testing of a single-chip microcomputer, the process of which is as follows figure 1 shown, including the following steps:

[0023] Step S11: provide the microcontroller programming file;

[0024] Step S12: the transcoding software converts the programming file of the single-chip microcomputer into a programming vector;

[0025] Step S13: The machine test program first calls the programming vector to make the test machine program the single-chip microcomputer, and then calls the test vector to judge the fault of the single-chip microcomputer.

Abstract

The invention discloses an on-line programming test method of a single chip microcomputer, belonging to the technical field of the single chip microcomputer. At first, that burn-write file of the single chip microcomputer is provides; then the transcoding software converts the singlechip burning and writing files into burning and writing vectors; finally, the testing program of the machine first calls the burning and writing vector to make the testing machine burn and write the MCU on-line, and then calls the testing vector to judge the fault of the MCU. The conventional method of burning andwriting and testing of single chip microcomputer is classified as online burning and writing test, which solves the limitation of burning and writing of downloader, and is simple and easy to operate.Compared with the conventional downloader programming test method, the method has the advantages that the hardware cost is reduced, the manual operation in the test process is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of single-chip microcomputers, in particular to an online programming and testing method of single-chip microcomputers. Background technique [0002] Single-chip microcomputer is a kind of integrated circuit chip, which is composed of central processing unit, random storage access device, read-only memory, various input and output ports, interrupt system, timer and other functions integrated on a silicon chip by VLSI technology. A small but complete microcomputer system, widely used in the field of industrial control. [0003] The conventional single-chip programming test method is to separate programming and testing, mainly use the host computer to download the programming program to the single-chip microcomputer through the data communication interface, and then input and read the output through the test equipment, so as to judge the quality of the single-chip microcomputer. However, conventional testing ...
