Universal serial communication interface debugging device and method

Abstract

It's a kind of common serial communication interface commission apparatus. It comprises computer module (101), micro controller small system (102), the first communication module (105), the second communication module (106), the N communication module (107), programmed logical module (103), clock module (104); the computer module (101) finishes the man-machine interface, and communicates with micro controller small system (102) through RS232 interface, so to finish the issue of deployment command or send and receive data; the micro controller small system (102) responds the control and subsequence to each communication module; the programmed logical module (103) finishes the function that system chip selecting and address decoding; the clock module (104) can synchronize the clock in this apparatus and external clock. This invention makes the commission of common serial communication programmed and modularized.

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 include HDLC (High level Data Link Control, advanced data link control procedure), HW (HighWay, PCM pulse code modulation transmission line), RS232, RS485, I 2 C (Inter-IC, internal integrated circuit bus), SPI (Serial Peripheral Interface, serial peripheral interface), etc., in the process of developing electronic information systems or industrial control systems, hardware developers need to debug and test various components in the system. Serial communication interface, but th...
