【Abstract】For the needs of communication between a variety of communication networks and interfaces in the same network which coexist in large-scale systems, a conversion module which supports communication between a variety of communication networks and interfaces is developed based on LPC2368 and the real time operating system of RTL-RTX. The module supports the communication between Ethernet, serial network,
CAN(fieldbus network) and USB, as well as RS232, RS422 and RS485 communication interfaces. The limit conditions to use the conversion module
are pointed out based on the quantitative analysis for the conversion rate in the network wire-speed.
【Key words】LPC2368 microcontroller; communication network; line-speed
