Next, we will add some output LEDs that the AVR can drive to indicate the acceleration values as it reads them out.

这是LPC1788掉电检测的程序,用于当由突发状况系统掉电时，紧急数据的保存，以免数据丢失。(This is the LPC1788 procedure of Brownout detection . In order to avoid data loss when power systems, emergency data is preservated.)

For Jamp Board (ARM9 develop board from Design gateway)

ADS教程 在这一章里，将介绍ARM 开发软件ADS(ARM Developer Suite)。通过学习如何在CodeWarrior IDE 集成开发环境下编写，编译一个工程的例子，使读者能够掌握在ADS 软件平台下开发用户应用 程序。本章还描述了如何使用AXD 调试工程，使读者对于调试工程有个初步的理解，为进一步的 使用和掌握调试工具起到抛砖引玉的作用(ADS Directory in this chapter, will introduce the development of software ARM ADS (ARM Developer Suite). Through the study of how the CodeWarrior IDE integrated development environment to prepare, compile a project examples, so readers can grasp the ADS software platform developed under user applications. This chapter also describes how to use the AXD debugger works, and readers for debugging project of a preliminary understanding, in order to further the use and control of debugging tools to initiate play the role)

1.传感器适用于土壤的湿度检测； 2.模块中蓝色的电位器是用于土壤湿度的阀值调节，顺时针调节，控制的湿度会越大，逆时针越小； 3.数字量输出D0可以与单片机直接相连，通过单片机来检测高低电平，由此来检测土壤湿度； 4小板模拟量输出AO可以和AD模块相连，通过AD转换，可以获得土壤湿度更精确的数值； 使用STM32驱动时，一般使用ADC读取其模拟量输出，以gokit stm32f103c8t6为例；">

stm32 sim900a 实现stm32拨打电话与接听电话(stm32 sim900a )

说明：  QN8027初始化代码，使用单片机是STM32.(QN8027 initialization code, the use of single-chip STM32.)

在万利199元开发板实现了STM32的定时中断功能，1秒钟产生一次中断，并且控制led在中断时闪烁。(199 yuan in Wanli STM32 development board implements the timer interrupt function, a second generating an interrupt, and interrupt control led flashes.)
