安富莱modbus教程，源码讲解，希望能够帮到大家。(Anfulai modbus tutorial, source code explanation, hope to help you.)

static members source code for object oriented environment

LABjs 的核心是 LAB（Loading and Blocking）：Loading 指异步并行加载，Blocking 是指同步等待执行。LABjs 通过优雅的语法（script 和 wait）实现了这两大特性，核心价值是性能优化。LABjs 是一个文件加载器。(LABjs lets you load pretty much any script file, whether you control it or not, with no intrusion or convention for dependencies, other than the order and blocking that you define. It keeps track of what you ve asked for and what has downloaded, and lets you only define a handler once for a group of scripts that will execute together in parallel. The API style (with chaining) makes is very easy to convert a set of script tags in your page into code to load them, without having to worry that race conditions will cause issues for scripts loading in the wrong order if there are explicit dependencies involved.)

液晶显示屏OCMG源程序代码，采用的方式为串口驱动。(LCD OCMG source code, the approach for the serial port driver.)

说明：  利用串口发送指令，来控制步进电机的转动方向和步数，同时利用LCD液晶显示转动情况(XX)

说明：  自主学习PIC芯片，此书主要讲PIC16F877(Self-learning PIC chip, this book mainly talks about PIC16F877)

基于STM32单片机，通过W5500以太网芯片下载APP的IAP程序，实测正常使用。(Based on the STM32 microcontroller, download the APP IAP program through the W5500 Ethernet chip, and measure the normal usage.)

空调压缩机变频控制算法，与直流无刷永磁电机相关，与节能相关。(PWM control algorithm of air-conditioner s condenser )

通过GPIO口，模拟I2C协议，和设备进行I2C通信(I2C communications via GPIO ports, analog I2C protocol, and equipment)

Stm8 I2C总线硬件I2C设备,总线挂载4片单片机，均为Stm8单片机,每一片单片机都可以做主从切换,测试可以正常通信。(Stm8 hardware I2C bus mount four I2C devices, are stm8 microcontroller, every piece of single-chip computer can make decision the switch, the test can normal communication.)
