A CAN Bus Data Acquisition System Based on Atmega8515

摘要：

A CAN Bus data acquisition system based on Atmega8515 is developed according to the particular features of a weapon system in this paper, in which data acquisition systems construction, principle and developing techniques are discussed in details. Furthermore, design of Atmega8515 systems circuit, including port circuit and driving programs, etc, are described. In order to avoid interfering weapon system, not only isolation methods is used between data acquisition equipment and weapon system, but also only receiving method of acquiring data from weapon system, which means not transferring any data to CAN bus, is adopted. In addition, GPS-OEM card and MCU counter are used to obtain standard time with high precision to satisfy the real-time requirement.
