Device and method for debugging serial communication interface

Abstract

The invention discloses a device and a method for debugging a serial communication interface. The device comprises a computer module (101), a microcontroller mini system (102), a first communication module (105), a second communication module (106), ..., an N-th communication module (107), a programmable logic module (103), and a clock module (104); wherein the computer module (101) is used for completing a human-computer interface, communicating with the microcontroller mini system (102) through an RS232 interface, and completing sending of a configuration command or transceiving of data; themicrocontroller mini system (102) is used for completing control and connection of the each communication module; the programmable logic module (103) is used for completing functions of chip selection and address decoding of the whole system and so on; and the clock module (104) is used for synchronizing a clock of the device and an external clock. Through adoption of the device of the invention,debugging of conventional serial communication becomes programmed and modular, thereby facilitating debugging and testing of various serial interfaces in electronic information and industrial controlsystem development.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to the communication interface debugging of multiple serial communication modes in the fields of electronic information and industrial control. Background technique [0002] In electronic information and industrial control systems, information is often exchanged between boards in the same system or between different systems through serial communication. The commonly used serial communication forms are HDLC, HW, RS232, RS485, I 2 C, SPI, etc. In the process of developing electronic information systems or industrial control systems, hardware developers need to debug and test various serial communication interfaces in the system, but the existing computer systems only provide standard RS232 interfaces for communication with external interface, but for HDLC, HW, RS485, I 2 C, SPI and other serial communication forms do not have a common debugging interface device, and usuall...
