Problems solved by technology

[0005] However, most of the existing offline programmers use SD card as the storage medium of the source program, which increases the cost of use. Since the SD card is a mechanical interface and requires frequent reading and writing, it greatly reduces the service life and the service life of the source program storage medium. stability
At the same time, these offline programmers can only be used to burn programs offline, and cannot update the programs in the flash memory of the hardware chip, nor can they be used as program debuggers, with a single function
Although there are some multi-functional offline programmers with the functions of programming and debugging programs, they are expensive and have complicated interfaces, making them inconvenient to carry on site

Abstract

The invention provides a portable multifunctional offline programmer. The portable multifunctional offline programmer comprises: a master control MCU module; a Flash memory, wherein large-capacity readable and writeable operation is arranged in the Flash memory, and the Flash memory is used for storing a Firmware program and a source program of the offline programmer; a USB interface used for exchanging data with other external devices; an SWD interface used for debugging the programs, carrying out offline programming and updating the source program; an instruction reception and execution module used for the offline programmer to execute all functions; and a running state display module used for displaying all running states of the offline programmer. The portable multifunctional offline programmer can realize offline program programming and update the programs in the hardware chip Flash memory, and also can be used as a program debugger.

Description

technical field [0001] The invention relates to the field of embedded electronic products, in particular to a portable multifunctional off-line programming device. Background technique [0002] In the production process of electronic products, it is necessary to use a programmer to download the software execution code to the hardware chip Flash memory. The programmer is a tool mainly used for chip programming of single-chip microcomputers. [0003] In the traditional burning process, a complete set of devices such as a PC, a burner, and a software development environment are needed to complete the burning of the program, and the operation process is complicated. [0004] With the development of technology, offline programmers have been produced one after another. The program files are stored in the programmer in advance, and then downloaded to the Flash memory of the target chip. The entire burning process no longer requires a PC and a software development environment, that ...
