Problems solved by technology

[0007] Due to the lack of monitoring means, the complexity of the above factors has caused us to encounter a lot of trouble in the process of designing and debugging the serial communication interface. The existing emulators and debuggers have their own limitations and cannot be compared with the actual target to be debugged. The modules work together, which cannot meet the requirements of flexible transformation of communication formats and working methods

Embodiment Construction

[0042] Structurally, a configurable universal synchronous asynchronous serial communication debugger is characterized in that the debugger includes a main processor module 1, a storage module 2, an Ethernet interface module 3, a serial port console module 4, and a USB host interface module 5 , a general synchronous asynchronous serial interface module 6 , an EPLD module 7 and a power supply module 8 . Wherein the main processor module 1 is the core of the system, it is connected with the storage module 2 through the memory bus, the main processing module 1 is connected with the serial port console module 4 through the debugging serial port, and is also connected with the Ethernet interface module 3 through the MII interface, the main processor Module 1 is connected with USB host interface module 5 through USB interface, and universal synchronous asynchronous serial interface module 6 is responsible for driving and outputting different synchronous or asynchronous serial communic...

Abstract

The invention is a configurable general synchronized / asynchronized serial communication debugger and debugging method. The debugging method consists of two modes: one is interactive, another is. In the first mode, two serial ports works independently, to cooperate with the target module of the debugging respectively; in the second mode, the two serial ports together with the target debugging module forms a ring, to participate the communication among target modules. Serial port debugging program works on host processors, which can be divided into two parts: configuration managing program and debugging program.

Description

technical field [0001] The present invention is a serial communication debugging device and its debugging method applied in the field of communication, computer and automatic control, especially a configurable universal synchronous and asynchronous serial communication debugging applied to various serial communication formats Device and its debugging method. Background technique [0002] Serial communication is the most widely used communication method in the fields of communication, computer and automatic control. It has the following advantages: [0003] ●The number of physical connection lines required is small; [0004] ●A large number of ready-made communication sample programs are available; [0005] ●A large number of serial interfaces of existing products are convenient for interconnection and intercommunication; [0006] In actual products, there are many formats of serial communication because of different application occasions. First, the mode of serial commu...
