Microchip PIC18 MCU series beginning routines

利用单片机加控制直流电机，利用P1口，编制程序输出一串脉冲，经放大后驱动小电机，改变输出脉冲的电平及持续时间，达到使电机正转、反转、加速、减速。停转之目的。 可以通过74LS244输入开关量数据来控制小直流电机的转动，实现正转四种转速，反转四种转速及停转。 -The use of SCM in controlling the DC motor

本设计主要是运用单片机设计一个最小系统――电子时钟，它具有24小时计时功能，能够对时间进行调整，并且能实现时、分、秒的显示，同时还有内设闹钟，时间到时候会响铃，响铃时可以通过按键控制延时再启动或关断。与此同时还设置了整点报时功能；并采用采用了软件去抖的方法扫描键盘，动态刷新显示数码管，并通过查表实现译码输出时间等编程方法；-This design is the use of single-chip design of a minimum system- Electronic clock, it has a 24-hour timer function, capable of time to adjust, and can achieve the hours, minutes and seconds display, but also equipped with alarm clocks, time to When ringing the bell to ring when the button control can delay re-start or shutdown. At the same time also set up the whole point timekeeping function and adopt the use of the software to scan the keyboard shaking method, dynamic refresh display digital tube, and through the realization of decoding look-up table output time programming method

基于51的12864串联代码,方便大家使用12864，并且可以节约端口啊-51 12864-based serial code, and to facilitate the use of 12864 people, and can save the port ah

基于AVR单片机的机械旋转时钟，将机械和电子完美的结合，具有一定的艺术性，做好后放在家里可以当艺术品-Based on AVR microcontroller mechanical rotary clock, would be the perfect combination of mechanical and electronic, has a certain artistic quality, do a good job at home can be as works of art after
