555定时器（时基电路）是一种用途广泛的模拟数字混合集成电路。1972年由西格尼蒂克斯公司（Signetics）研制；设计新颖、构思奇巧，备受电子专业设计人员和电子爱好者青睐；它可以构成单稳态触发器、多谐振荡器、施密特触发器和压控振荡器等多种应用电路。5 55定时器是一种中规模集成电路，它使用灵活、方便，被广泛应用于脉冲的产生、整形、定时和延迟等电路中。文中介绍了555定时器及其逻辑功能，以及由其构成的多谐振荡器的工作原理，通过举例论述了555多谐振荡器在模拟救护车声响电路中的应用，说明在实际生产中，只要将其各个功能加以综合应用，便可得到许多实用电路。 (555 timer (time base circuit) is a versatile analog-digital hybrid integrated circuit. Trinity Lakes in 1972 by Sigma Corporation (Signetics) development layout and design, the idea of Kit Kat, much electronics design professionals and electronic enthusiasts favor it can constitute a monostable, multivibrator, Schmitt Triggers, and a variety of applications such as voltage-controlled oscillator circuit. 5 Timer 55 is a medium scale integrated circuit, which uses a flexible, convenient, and is widely used in pulse generation, shaping, timing and delay circuits. This paper introduces the 555 timer and logic functions, and its composition multivibrator works, discussed through the example of 555 ambulances multivibrator sound in analog circuit applications, showing in the actual production, as long as Will be integrated application of its various functions can be many practical circuits. )

STM3210E-EVAL官方开发板，主芯片STM32F103ZET6，支持ucLinux开发，官网也给出了开发套件。但是官网没有给出BOOT的源代码，只有HEX文件（根据推测该HEX文件时KEIL生成的）。看过UBOOT的启动后，了解了BOOT启动都干些什么事，我仿照UBOOT在KEIL软件下写功能超级简单的BOOT，就是完成外设的初始化，初始化控制器串口1，经过验证，可以跳转到内核，内核能够实现printf打印输出。(The Boot of STM32F103 uCLinux development)

计步器，基于单片机与ADXL三轴加速度传感器的计步器，实现计步、1602显示步数及平均速度功能。 ( Pedometer, pedometer-based SCM and ADXL triaxial accelerometer achieve pedometer, 1602 show the number of steps and the average speed function.)
