Abstract：In this paper,TJA1040 is used as CAN transceiver to connect physical bus and CAN controller,build bus-type structure communication platform,realize CAN signal differential transmission and reception,study the influence of terminal resis?tance on signal amplitude,and give terminal resistance configuration suggestion under long-distance communication conditions. A star topology platform is built,and the optimal configuration scheme of the star structure terminal resistance is explored. Different terminal resistances are configured according to different situations,which is beneficial to improve CAN communication effect.
