ESP8266 PWM控制一盏LED的亮度变化。(ESP8266 PWM controls the brightness change of an LED.)

说明：  非编码键盘是利用MCS—51单片机内部的定时/计数器、中断系统、以及外围的按键和LED数码管显示等部件，设计一个单片机非编码矩阵键盘。并能通过按键实现显示0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F。(The keyboard is used non-coding MCS-51 microcontroller internal timer/counter, interrupt system and the external buttons and LED digital display and other components, to design a single chip non-coding matrix keyboard. And pass the key to achieve display 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F.)

基于stm32程序，按键扫描，控制led灯反转(It s a keypolling procedure controlled by stm32 to make the led trigger)

说明：  最新超低功耗,超高速 51单片机的资料.非常难得.(a new ultra-low power consumption,ultra high speed 51 signal-chip book.)

Ti轻量级OSAL移植到STC12C5A60S2使用keil编译环境(Ti OSAL lightweight portable to use keil compiler environment STC12C5A60S2)

说明：  内涵STM8S的库，集成个人修改的文件 已经检验(Library of Connotation STM8S)

说明：  msp430g2553使用1306显示超声波测距(2553 Displays Ultrasound Ranging by 1306)

系列语音温度控制器适用于别墅、公寓、办公楼及工业商业等,用于控制中央空调、水采暖、电采暖的恒温控制,达到调节室内温度保持恒温及舒适节能的目的。(The series voice temperature controller suitable for villas, apartments, office buildings and industrial commercial, used to control central air conditioning, water heating, electric heating thermostat control, reach adjust the indoor temperature to maintain constant temperature and comfort energy saving purposes)

here is a document describing KEy pad decoding techniques and C++ source code as well. it is show 74ls138 role in decoding.. hope it will be helpful. THANKS
