Embodiment Construction

[0036] The implementation method will be described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 Shown: Background system structure diagram

[0038] The background adopts a layered structure, and the bottom layer is to package the physical driver modules separately, mainly to write drivers for unreasonable communication interfaces.

[0039] The data link module is responsible for unframing the data received by the separately encapsulated physical drive module, and framing the data sent by the upper layer. Specifically, it determines how to frame and unframe according to different protocols.

[0040] The front-background communication is the front-background communication interface used by the background debugging system. It is done according to different protocols specified by the developer during the application. It mainly provides a general interface function for the developer. The developer only needs to call the corresponding int...

Abstract

The background monolithic computer debugging system includes at least one physical driving module, one data link module, one foreground and background communication module and one application function module. The physical driving module establishes links between the background monolithic computer debugging system and the monolithic computer application system via the serial port or extension facility, the data link module completes the data transmission and processing between the physical driving module and the foreground and background communication module, the foreground and background communication module completes the data transmission between the data link module and the application function module. In the said system, the user may tailor equipment and develop new debugging method. The present invention facilitates the development of monolithic computer.

Description

technical field [0001] The invention relates to a single-chip microcomputer application system, in particular to a background debugging system for an 8051 single-chip microcomputer. Background technique [0002] 8051 and its compatible series of single-chip microcomputers are widely used in various electrical appliances and communication products as an industrial standard technology. Generally speaking, the application process of single-chip microcomputer is like this. First, burn the MCU program through the burner, and then plug the MCU into the power supply. For developers, there may be a lot of printing information in the program. These printing information can be sent to the hyper terminal through the serial port or displayed in the specified window through other physical devices. In addition, there is only continuous observation of the printed information. information. When the single-chip program is interrupted or the single-chip application system fails, it is gene...
