在将嵌入式实时操作系统μC/OS-II成功移植到TMS320LF2407A型号的DSP的基础上,论文介绍了如何在电力系统集散式的数据采集系统中基于μC/OS-II实时系统开发相应的CAN总线远程通信模块。阐述了μC/OS-II多任务操作系统通信机制和中断机制,详细分析了在DSP实时模式下CAN总线驱动的实现过程。
Based on the successful transplanting of embedded real-time operating system μC / OS-II to TMS320LF2407A DSP, this paper introduces how to develop the corresponding CAN bus based on μC / OS-II real-time system in the distributed data acquisition system of power system Remote communication module. The communication mechanism and interrupt mechanism of μC / OS-II multitasking operating system are expounded. The realization of CAN bus driving in DSP real-time mode is analyzed in detail.
