摘要
由于目前USB设备多是由专门的USB控制芯片来实现其应用控制,芯片内集成了USB协议,成本较高,PCB板的面积较大。对于成本敏感的应用有很大限制。本文提出了仅用一片MCU(微处器-单片机)或嵌入式系统芯片来实现其与PC机通讯的方法。该方法使用微控制器仿真USB设备,极大地方便了用户的开发,同时降低了功耗、成本。
Because USB devices are controlled by special USB chip to achieve its application control, within the chip the integrated USB agreement , cost are higher , unnatural area of PCB is bigger. It Restrict the application of cost-sensitive . In this paper, it has been coceived using a MCU or embedded system chips to achieve their communication with the PC machine. This method is the use of USB microcontrollers simulation equipment, which greatly facilitated the development , while reducing power consumption and cost.
