以AVR单片机ATmega8和USB接口器件PDIUSBD12为核心，基于标准的USB1.1协议，设计一种通用USB接口模块，以满足嵌入式系统中对USB接口的需求。对模块的硬件电路或单片机固件程序的硬件接口层稍加修改即可用于其他各种微处理器。该模块可为各种嵌入式系统增加USB接口,实现与USB主机系统通信。
- Abstract:
- Based on AVR microcontroller ATmega8 and USB interface chip PDIUSBD12, a general USB interface module is designed according to USB1.1 protocol for various requirements of embedded systems. Only with few modifications in circuit or hardware abstract layer of firmware, the module can be used on many types of microprocessors. All kinds of embedded systems can realize high speed and stable communication with USB host systems, owing to the facility of this module.
