使用89S52为核心做的USB键盘,注意修改了一下windows设备描述符以及端点处理等就行了。用了一个4*4的小键盘,有0-9十个数字键, Num Lock键,Caps Lock键,Shift键,Ctrl键,Alt键,回车键等。 最多可以有三个键同时按下，如果相交的话，最多只能两个键按下-89S52 use as the core of the USB keyboard to do, pay attention to modify the look and the windows device descriptor, such as treatment endpoint on the list. Used a 4* 4 small keyboard, has the number keys 0-9 10, Num Lock keys, Caps Lock key, Shift key, Ctrl key, Alt key, enter key and so on. Can have up to three keys pressed at the same time, if the intersection, then a maximum of only two keys pressed

I2c如 IIc 24LC64等器件的51单片机驱动程序,已经通过实际验证,很好用的-I2c such as IIc 24LC64 51 microcontroller device driver, has been through actual test Oh good use

】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.
