Abstract

The invention relates to the technical field of automotive electronics, in particular to a controller area network (CAN) bus signal transceiving analysis tool. Compared with CAN bus signal transceiving analysis tools in the prior art, the CAN bus signal transceiving analysis tool has the advantages that the structure of the CAN bus signal transceiving analysis tool and an inner circuit structure with a clock circuit, a joint test action group (JTAG) interface circuit, a data buffering circuit, a universal serial bus (USB) interface-to-serial port circuit and a CAN bus communication circuit are designed, and thereby, CAN message sending, real-time receiving and analyzing can be achieved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a CAN bus signal sending and receiving analysis tool. Background technique [0002] At present, CAN bus signal debugging tools are limited in number, expensive, and monopolized by foreign companies. At the same time, some CAN bus signal debugging tools do not have signal analysis functions and are not easy to use. [0003] In order to facilitate the sending, receiving and analyzing of CAN bus signals in vehicle communication-related tests and test applications when testing EPS electronic power steering systems, it is necessary to design a CAN bus that can realize the sending and real-time receiving of CAN messages and realize the analysis of CAN messages. Bus signal transceiver analysis tool. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a CAN bus signal sending and receiving...
