摘　　要：本文介绍了一种基于ISP1161的手机USB数据线测试仪的设计方案,详细介绍了其测试原理,以及系统硬件及软件设计与实现。该方案以USB接口芯片ISP1161为USB主机,以USB接口芯片PDIUSBD12为USB设备,以STM32为主控制器;根据USB2.0协议把USB数据包通过USB主机发送,通过被测USB数据线传到USB设备,然后计算USB数据包的出错率来判断USB数据线性能的好坏。The design scheme of a USB data wire test instrument based on ISP1161 was introduced in this paper, The testing principle, hardware and software design and implementation of the system were described in detail.The program uses USB interface chip ISP1161 as the USB host, USB interface chip PDIUSBD12 as the USB device, STM32 as the main controller.According to the USB2.0 protocol, the USB data packet is sent through the USB host and transmitted to USB device through the tested USB cable.And then calculate the error rate of USB packets to determine the performance of USB data cable is good or bad.
