摘　　要：随着成像测井仪器的研发,成套测井仪器内部需要大量的数据快速准确的传输,而现在仪器内部的数据传输速率大约仅有300 k/s,远远满足不了测井仪器发展的需要。根据设计时的步骤,将从3个方面:CAN与DSP的接口电路、波特率的设定及初始化子程序论述在ADSP2181的CAN总线通讯。设计完成后使数据传输速率达到1 Mb/s,满足了仪器内数据传输的需要。With the development of imaging tool, the sets of imaging tool interior need to transmit data fast and accurately. Now there are only about 300 k/s in it,that can not satisfy the development. According to the designing steps,the article discusses CAN communication of basic on ADSP2181, from the interface circuit of CAN and DSP, designing the baud rate and the initialization subroutine. Untimately,the rate of data transmission is accomplished 1 Mb/s after the design completeness, which contents the need of data transmission in imaging tool.
