摘　　要：详细介绍了一种利用USB转UART桥接芯片CP2102来完成气动打标机USB接口设计的方法．首先对各种USB接口芯片进行比较，完成USB接口芯片的选型．然后简单描述气动打标机的系统设计，重点介绍USB接口硬件电路设计和软件设计．在软件设计中利用Keil C51开发工具μVision2的集成开发环境和VC＋＋实现了单片机与上位机的通信协议．经实际应用表明，本设计具有低成本、设计简单等优点，能够完成单片机与上位机之间准确、快速地数据传输．In order to solve the pneumatic marker using serial ports communication disadvantages and USB devices of complex develop problems, a design method is introduced in this paper using a USB turn UART bridge chip CP2102 to complete the pneumatic marker USB interface. First of all,compare the various USB interface chip to complete the selection of USB interface chip. Then take a brief description of pneumatic marker system design, focusing on USB interface＇s hardware design and software design. In the design of software development using Keil C51 tools μVision2 integrated development environment and VC＋＋realizing the MCU and PC communication protocol. In the actual application, this design has advantages of low cost, simple design etc, can finish accurate and rapid data transmission between MCU and PC.
