STM32 ADC,所用的是神舟开发板，STM32芯片是STM32F107VCT6(STM32 ADC，the STM32 micro core is STM32F107VC)

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)

学4年来做过的竞赛以及老师的科研项目所积累下来的c51源代码，一共有40(4 years of study done as well as the Teacher of the competition accumulated research c51 source code, a total of 40)

这是Small RTOS 51 在DP－51下载仿真实验仪上使用CAT24WC02驱动程序的例子。本例程序按照相应的的通讯协议接收一个数据，并将接收到的数据显示到LED数码显示器上。然后将接收到的数据写入Cat24Wc02中，再在同一位置将数据读出，并将读出的数据通过串口发送回来。通讯协议参考rtos随想曲和test.ini。 (This is the Small RTOS 51 DP-51 download simulation NG use CAT24WC 02 Driver for example. The cases in accordance with the relevant procedures of receiving a communication protocol data and receiving the data shows that the LED digital display. Then sending the data into Cat24Wc02, again in the same position will be read out data, will be read out through the serial data sent back. Communication protocol reference rtos test.ini and Capriccio.)

板载三个灯同时亮灭，板子上可以看到灯发出闪烁的白光(On-board three lights turn on and off at the same time)

一些单片机常用的源代码，用C编写的，郭天翔编写的(Some SCM common source code, written in C)

使用IAR编译，单片机基本应用，SPI的仿真，实用的是使用PROTEUS仿真(The use of IAR compiler, microcontroller basic applications, SPI simulation, and practical is to use the PROTEUS simulation)
