摘要
介绍了基于PDIUSBD1 2芯片的USB设备硬件组成 ,详细论述了USB枚举的具体过程和基于PDIUSBD1 2的MCU固件编程思想 ,给出了部分单片机C程序代码 ,分析了制约实际数据传输速率的原因 。
This paper introduces the hardware constitution of a USB device based on PDIUSBD12. The emphasis is how to enumerate a USB device and how to program firmware. This paper offers parts of MCU C language programs, analyses the reason why the real data transfer speed is restricted, and offers the solution.
