本设计采用Cypress公司支持USB2.0协议标准的EZ-USB FX2系列之CY7C68013芯片作为帧同步信号发送器的USB接口芯片，在uVision2开发环境下利用Keil C51完成了满足帧同步信号发送器基本要求的固件设计，具体采用了批量传输方式、大端点三缓冲设置、定时器中断方式的同步脉冲和数据的发送、软FIFO方式数据存放以及I2C总线下的LED显示等技术，最后协助编写USB底层驱动程序实现了固件自动下载。经过测试，所设计的帧同步信号发送器基本达到了课题所要求的基本原理性设计与验证。

-This design uses Cypress supports USB2.0 protocol standards of EZ-USB FX2 Series CY7C68013 chip as a fr a me synchronization signal transmitter of the USB interface chip, in uVision2 development environment using Keil C51 completed a fr a me synchronization signal to meet the basic requirements of transmitter firmware design, specific use of a bulk transfer mode, the endpoint buffer three settings, the timer interrupt the sync pulse and data transmission, soft FIFO mode and the I2C bus data repository under the LED display technology, assist in the preparation of the final bottom USB driver to achieve the firmware is automatically downloaded. After testing, the design of fr a me synchronization signal transmitter basic subjects required to achieve the basic principles of design and verification.
