这是avr单片机pwm输出程序，是电机控制不可缺少的，也是控制类里面比较重要的程序，好好学习一下吧(This is the avr microcontroller pwm output process, motor control is indispensable, and it is more important to control the class inside the program, learn about it)

英飞凌单片机使用pec中断的ad转换实例完整版(Infineon microcontroller interrupt the ad conversion using pec)

说明：  STM32_SX1278实现LORA通信STM32F103完美实现(STM32_SX1278 achieves perfect implementation of LORA communication STM32F103)

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

说明：  ESP8266 官方无OS 版本 SDK(ESP8266 guangfang SDK)
