【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.
【Key words】Real-time operating system; μC/OS-II; Embedded BACnet gateway; Real-time schedule
