51单片机开发入门与典型实例书籍源码，示例源程序注释清晰易懂，是51单片机开发入门非常好的实例程序(51 asm example program)

说明：  常见的单片机操作，IO，中断，定时器，低功耗模式等(io, interrupt, timer, low power mode and so on)

基于51单片机的LCD1602的开发程序（C）(LCD1602 51 MCU-based development process)

stm32高级定时器1产生两路相位差180度PWM，频率、占空比可调。(STM32 produces two phase difference 180 degree PWM)

本程序使用tcs34725传感器和51单片机，识别颜色。将颜色转换为对应的色坐标并在1.3寸液晶上显示色坐标的值(This program uses TCS 34725 sensor and 51 single chip computer to recognize color. Convert the color to the corresponding color coordinate and display the value of the color coordinate on the 1.3 inch liquid crystal.)

自动存包柜的几个功能模块程序。这个LCD显示屏128x64的程序等。(Automatic deposit packet counters, function block.)

　Hittite公司以创新的设计使得其PLL产品性能优异，在相位噪声，杂散方面有着卓越表现，其芯片的高集成度使得外围电路简单，设计方便。所以随着电子技术的发展，对频率源的相位噪声性能要求越来越高，Hittite的低相位噪声PLL，在物理、天文、无线电通信、雷达、航空、航天以及精密计量、仪器、仪表等各种领域里都将大有用武之地。(The Hittite companies with innovative design makes the PLL excellent product performance, the phase noise, spurious aspects with excellence, its high integration chip makes the peripheral circuit is simple and easy design. So with the development of electronic technology, phase noise performance of frequency source is more and more high, the Hittite low phase noise PLL, in physics, astronomy, radio communication, radar, aviation, aerospace and precision measurement, instruments, meters and other fields will be great.)
