利用AVR单片机实现的慢速USB设备协议

】本文介绍了一个使用单片机和CPLD联合控制步进电机的方案。首先阐明步进电机的工作原理及控制方法，然后 提出了系统的软硬件设计框架，详细讨论了单片机和CPLD的逻辑接口问题和交换数据的协议，以及用状态机来设计脉冲分配器 的方法。-This paper describes a combined use of SCM and CPLD stepper motor control program. First of all, to clarify the working principle of stepper motor and control method, and then put forward a system of hardware and software design framework for a detailed discussion of the MCU and CPLD logic interface issues and data exchange agreements, as well as the use of state machine design Pulse Distributor methods.

程序描述：使用Cypress的Cy7C68013A芯片进行设计，控制外部LED数码管的显示。程序包括USB固件程序以及主机程序。 安装：把源码拷贝到硬盘特定目录下，使用Keil C编译器和Visual C++ 6.0运行即可。 注意：可以首先使用Cypress的调试工具进行固件程序的调试，以确保固件程序的正确性。 -Description: Using Cypress

如何使用USB总线接口在单片机系统中实现一个虚拟串口的原理和实现过程。在设计中，软件部分采用USB的CDC类标准来实现虚拟串口，这样可以使用操作系统（Windows,Linux）自带的驱动程序；在硬件设计中，使用自带USB从设备接口的AT89C5131单片机，提高了系统的集成度和可靠性-How to use the USB bus interface in single-chip realization of a virtual serial port system, the principle and implementation process. In the design, the software part of the adoption of USB-CDC class standards to achieve a virtual serial port, so you can use the operating system (Windows, Linux) comes with the driver in hardware design, the use of own USB interface from the device chip AT89C5131 machine, to improve the system integration and reliability of
