上位机示波器驱动程序，VS2010 C#版本，对于做控制的同学十分有用(PC oscilloscopes driver, VS2010 c# version, classmates are very useful for do control )

在keil上进行单片机语言编程，很实用的小例(Microcontroller programming language on the keil, very practical small cases )

实时闹钟.1、STM32的实时时钟（RTC）是一个独立的定时器！ 2、RTC模块和时钟配置系统（RCC_BDCR寄存器）是在后备区域，即在系统复位火从待机模式唤醒后RTC的设置和时间维持不变。 RTC这章中，对RTC相关的寄存器的操作特别重要，(RTC Alarm real-time clock timer; keyer; intervalometer; timing device clock; timepiece allocation; configure; collocation; deploy register; tell-table; temporary storage reserve; in support system resetstandby mode awaken; awakening; arouse; rouse; wake up stand)

一种简单的心率测量系统设计，能显示并进行上下限报警(A simple heart rate measurement system design, and upper and lower alarm)

前视双基地SAR（Bistatic Forward-looking SAR)(BFSAR)是对双基地工作模式的一种拓展，能对飞行路线正前方区域进行较高分辨率成像，能消除侧视模式中存在的固有成像盲区，是传统侧视模式的重要补充，具有自身不可替代的优越性。因此对于前视双基地SAR的深入研究具有相当的价值。(Forward-looking Bistatic SAR (Bistatic Forward- & SAR) (BFSAR) is a kind of double base work mode of development, can be directly in front of flight path area of high resolution imaging, can eliminate inherent imaging side-looking mode existing in the blind area, is an important supplement of traditional side-looking mode, has its own irreplaceable advantages. So for the front of the further research of bistatic SAR is quite valuable. )
