实验（一）开发环境的建立

周立功-《ARM与嵌入式系统基础教程》，以PHILIPS公司LPC2000系列ARM微控制器为例，深入浅出地介绍嵌入式系统开发的各个方面。随书源代码，包含3,4,6,8,9章的代码。(ZLG- " ARM-based tutorials and Embedded Systems" to PHILIPS' s LPC2000 series ARM microcontrollers, for example, learn more on various aspects of embedded system development. With the book source code, the code contains chapters 3,4,6,8,9.)

用stm32测量血氧饱和度和心率。传感器为max30102。在oled上显示。效果较好(Blood oxygen saturation and heart rate were measured by stm32. The sensor is max30102. Display on oled. get a good effect.)

实时时钟芯片的应用程序，电路连接详情见电子协会开发板( i do not how to translate it and click it with no resbound ,so you know)

说明：  Stm32F103C8T6的跑马灯库函数版(Stm32F103C8T6 Running lantern library function Edition)

It draws on principal component analysis algorithm (PCA), ICA (Principal Component Analysis) algorithm and procedures, Achieve a grayscale image and further control for video surveillance.

说明：  矩阵键盘 stm32 可以使用 4*4矩阵键盘驱动(stm32 key The matrix keyboard stm32 may use a 4*4 matrix keyboard driver)

LPC824官方固件库，可以很好的帮助初学者，对LPC800系列入门(LPC824 official firmware library)

用计时器实现的精准的延时程序的代码，希望对大家有用，基于LPC2103(With the timer delay to achieve the precise procedure code)

M051微处理器的定时器接口设置为pwm功能(M051 microprocessor interface is set to pwm timer function)

at91sam7a3在iar下的sdcard例程，调试通过，可以作为学习参考(at91sam7a3 the sdcard routine, under the iar through debugging, can be used as a study reference)
