KEIL_patch-V302

本设计主要实现用按键控制步进电机四相单拍、四相双拍和四相八拍三种方式切换， 正、反转及其加、减速，并能在LCD上显示其运行状态（速度和转向）。(The design of the main keys to achieve control of stepper motor with a single shot four-phase, four-phase two-and four-phase eight-shot shoot three ways to switch Positive, reverse its acceleration, deceleration, and in its operational status on the LCD display (speed and steering).)

2017年电子设计竞赛 ，G题 ：单相用电器分析监测，利用单片机驱动ATT7053读取电压电流等信息，进行分析监测。 基于KEIL5(2017 electronic design competition, G: single-phase electrical analysis and monitoring, using single-chip drive ATT7053 read voltage and current information, for analysis and monitoring.Based on KEIL5)

stm32f103c8t6 usb hid应用源代码。 源程序是103vct移植到103c8t6 适用。(stm32f103c8t6 usb hid source )

该程序是本人用AVR ATtiny13写的的一个只用4个IO口驱动两相四线制步进电机的程序，还可以控制转动的上下限（祥见程序屏蔽部分）对使用两相四线步进电机的初学者来说无疑是一笔珍贵的学习资源，对要求以最低成本驱动两相四线步进电机的使用者来说，更是提供了一个有利的参考。推荐！(I use the program is written in AVR ATtiny13 a four IO only I drive two-phase four-wire stepper motor program, but also can control the rotation of the upper and lower limits (祥见shielding part of the procedure) on the use of two-phase four-step beginners into the motor is undoubtedly a valuable learning resource for the lowest cost drive requires two-phase four-wire stepper motor users are provided a favorable reference. Recommended!)

蜂鸣器奏乐刘德华《练习》，根据不同的单片机可以调整延时。8952单片机不能执行程序，但将数组的xdata改为code可以演奏一小段。需要高级一点的单片机。在不同的开发板上运行的效果有差异。(Buzzer music to Andy, " practicing" , depending on the chip can be adjusted delay. 8952 microcontroller can execute the program, but will be replaced by code xdata array can play short. Require senior point microcontrollers. The development board running at different effects are different.)
