该程序使用消息邮箱，在内存空间开辟了一片区域，供4个任务共享读写。1个任务在写内存时，其它任务不能读写。多个任务可以同时读该内存区域数据。-This program uses the message mailboxes, the memory space to open up a regional, shared reading and writing for the four tasks. A task to write the memory and other tasks can not r

该项目的硬件环境是以LPC2148为核心芯片，软件开发环境是IAR，在此实现了主控对usb数据的读与写。-The hardware environment of the project is based on the the LPC2148 core chip, software development environment IAR, this master usb data read and write.

软件模拟FIFO队列，实现了队列的初始化，读写操作以及查看队列占用情况和可用空间情况。uCOS下测试通过，其中的数据类型定义没有添加，请使用者按照芯片自行定义。-FIFO queue simulation software to achieve the initialization of the queue, read and write operations, and view the queue occupancy and available space situation. uCOS un
