| Abstract: | Based on the experimental platform whose main controller is Samsung S3C2410 chip, this article designs and implements a more efficient baud rate adaptive CAN driver. In this paper, the CAN drive structure is introduced and the principle of baud rate adaptive CAN driver is explained in detail. This scheme is combined with the common polling method and sampling method. At the same time, a new scheme is proposed to improve the efficiency of the drive by adding the user''s input to the baud rate adaptive process. Finally, this paper carries out the data communication test and the performance analysis for this driver. |
