CAN COMMUNIATION MATRIX

USING CANdB++

//CREATED BY : AKASH.K

// CREATED ON DATE :20,october2022.

//SOFTWARE : VECTOR CANdB++

INTRODUCTION :

The Communication matrix or CAN Matrix is a table structure, essentially defining some of the basic informations about which ECU sends which message under which conditions and with which cycle time and which ECU receives the corresponding message or signal.

OVERVIEW :

Here,in this DBC I have implemented Sixty signals which are converted into Eight functional messages.These are the some of the major requirements which are needed to develop a communication matrix which plays a vital role in the CAN communication.

In such case the above mentioned sixty signals are the required messages for transmitting and receiving that could be the inputs which are given to the ECU systems to do work on a progress.
