stm32 cortex m3 pwm输出控制(pwm control)

单玉米 多目录 绑定转向 win32 sdk开发(single directory bundled with more corn to the development of win32 sdk)

利用51单片机做电阻测量仪，实现按键设置阻值自动报警提示(The use of 51 single-chip resistance measuring instrument to achieve automatic alarm button to set the resistance)

可以控制标签的各种状态，包括大小，字体等等，只要你能想到(Can control a variety of status labels, including size, fonts, etc., as long as you can think of)

基于MAP430F149单片机的典型例题，很有帮助(Microcontroller based MAP430F149 a typical example, very helpful)

利用但总线DS18B20测温程序，并在LCD显示，取三位有效小数位。整数部分两位。共5位显示。 可在利尔达MSP430F449开发板上直接实现功能。(However, temperature measurement procedure using the bus DS18B20 and LCD display, taking three decimal places effectively. Integral part of the two. A total of five shows. LSD MCU MSP430F449 on the development board can directly implement functionality.)

交通灯的开发，实现主道停留60秒，干道停留20秒，出现紧急情况采用按键控制(The development of traffic lights, the main road to stay 60 seconds, the trunk stay for 20 seconds, the event of an emergency using the button control)

用共阴极数码管做的密码锁,可修改密码 ( this is a codelock )

DHT11的C51驱动程序，4位数码管可以显示温度和湿度，带一触发按键(DHT11 C51 driver, four digital tube can display temperature and humidity, with a trigger button)
