Problems solved by technology

[0003] Usually, embedded system monitoring sends data to the host computer through embedded software communication, and the communication protocol is fixed. If the observed data needs to be changed, the software needs to be changed. For software with strict version control, the cost-effectiveness of the change is too high

Embodiment Construction

[0076] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0077] The invention provides an embedded software interaction method. The upper computer and the lower computer communicate according to a set interaction request protocol;

[0078] The interactive request instruction format in the interactive request protocol is "the first address and the second address command word data block", each part of the interactive request instruction is input using ASCII code, and the length is a character or an integer multiple of a character; in this embodiment Spaces are used as separators between each part, and "," or "." can also be used as separators; the user should find the correct address through the map file, and then follow the software interaction method proposed by the present invention for the upper computer and the lower computer. For interaction, the command word is the following capital letters: G, H, K, Q, W, P, Z;...

Abstract

The invention provides an embedded software interaction method. The upper computer sends an interaction request instruction to the lower computer according to different scenarios; Data at a specified address; read all data corresponding to an address range in batches at a time; read data at multiple specified addresses in batches continuously; password verification of write permissions; write specified values ​​at specified addresses; word length switching; can directly Response to key functions on the keyboard, such as N to read the next data, P to pause, and R to return. The invention makes the way for the user to obtain the software information of the lower computer more flexible.

Description

technical field [0001] The invention relates to an embedded system, in particular to an embedded software interaction method. Background technique [0002] When developing an embedded system, it is necessary to communicate with the lower computer to obtain the information of the embedded system. At present, the interaction between the lower computer software and the upper computer software is to send data according to a fixed communication protocol for the upper computer software to receive, analyze and save. [0003] Usually embedded system monitoring sends data to the host computer through embedded software communication. The communication protocol is fixed. If the observed data needs to be changed, the software needs to be changed. For software with strict version control, the cost-effectiveness of the change is too high. Contents of the invention [0004] The object of the present invention is to provide a kind of embedded software interaction method, the upper comput...
