本方案是基于富士通高可靠性单片机开发的锂电池电动螺丝刀，采用直流无刷电机作为核心，配合方波驱动以及闭环控制技术，实现电动工具的可靠运行。 技术参数 1）采用日本富士通MCU，性能稳定，抗干扰强，高可靠性； 2）直流18V输入（可兼容不同锂电池10V—36V）； 3）三相霍尔直流无刷电机驱动，转速高达25000转/分； 4）采用德国英飞凌高性能MOS/IGBT，驱动功率高达800W； 5）高亮LED照明，工作时点亮，不工作时自动熄灭； 6）采用智能控制技术实现待机（不工作时）功耗为 0 消耗； 7）通过软件实现软启动，启动时间可调整，瞬间（1S）达最高速； 8）具有过流保护、堵转保护、过压欠压保护； 9）带速度设置按键、正反转按键、调速开关； (The program is based on the Fujitsu MCU development of high reliability lithium battery electric screwdriver, brushless DC motor as the core, with the square wave drive and closed-loop control technology, power tools for reliable operation.)

本文详细介绍如何使用GAINS节点和我们开发的多跳路由协议的代码实现无线通讯功能的过程。涉及到avr单片机的编译器winavr，烧写软件avr studio以及avr系列单片机的烧写器，本文介绍如何使用avr studio 和烧写器将winavr编译后产生的hex文件存入单片机flash的过程。这个过程完成以后，就可以组织一个多跳的网络，通过SNAMP后台可以看到网络的可视化效果。(This paper describes how to use GAINS nodes and we develop multi-hop routing protocol code realize wireless communication process. SCM involves avr compiler winavr, software programmer avr studio, as well as programmer avr series MCU devices, the paper describes how to use avr studio and programmer will winavr compiled hex file generated into single-chip microcomputer flash process. After the completion of this process, we can organize a multi-hop network can be seen through the background SNAMP network visualization.)

此程序和上一个程序是用于51单片机和430单片机的通信，通信方式为单工，430做主机51做从机(This program and a program for 51 And 430 single-chip communication, means of communication for the simplex, 430 to do Host 51 to do slave)

关于转向泵的控制源程序，自己亲自运行调试了，完全可以放心使用。(Steering pump on the control source, and personally run debugging, you can rest assured that the use of.)
