Abstract: Embedded BACnet gateway has been constructed with singlechip LPC2106 and real-time operating system μC/OS-II. To satisfy with BACnet gateway’s real-time request, the paper studies the CPU execution speed, operating system’s time precision, memory management, and so on. Using μC/OS-II to schedule the gateway’s multi-task, embedded BACnet gateway’s real-time performance has been met.
