交通灯，使用定时中断来进行时间的加减，使用数码管进行显示，能够显示东西南北的红绿灯时间和灯的情况(Traffic lights, use the timer interrupt to the time of addition and subtraction, using digital tube display, it will show what traffic lights north and south of the circumstances of time and light)

基于STM32F10X的气压传感器（bmp180）程序，串口输出，内含bmp180手册。(Based STM32F10X pressure sensor (bmp180) program, serial output, containing bmp180 manual.)

单片机键盘控制,可用外接键盘来向单片机输入数字(control of the keyboard)

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).)

说明：  MSP430红外解码驱动，占用了一个定时器资源。(MSP430 IR decoding drive, taking up a timer resources.)

这是一份关于MSP430的C程序和课件，虽然不是很全面，但是对于新手还是够用的。(This is a report on the MSP430 C program and courseware, though not very comprehensive, but still enough for the novice.)

说明：  下面的程序利用友元函数求两点间的距离。请你将有关的程序补充完整，并总结为什么这里要用友元函数来求两点间的距离。(using friend to get the result.)

一个自制的小闹钟程序，程序可以配置，能够切换背景以及时间显示的外观，两者可以单独变换也可以一起变换。(A self-made small alarm clock program, the program can be configured, can switch the time display background and appearance, the two can be alone together can also transform transformation.)

超声波测距，测量精度为1cm，可以使机器人安全避障。(Ultrasonic distance measurement accuracy of 1cm, can make the robot obstacle avoidance safety.)

很久以前写的一个数码管取模软件，可做单片机来发辅助…(a MCU tool ,i ve written it when i was a freshman)
