基于单片机的函数信号发生器的C语言代码，自己做的(Function signal generator based on single chip microcomputer C language code )

说明：  This is a generic FIFO buffer that can be used to store any kind of items. It is written in C language and can be compiled and used on almost any architecture. It was designed to be used on memory limited architectures such as microcontrollers. Examples of the applications that can be built with this library include:

stm32f407使用OV2640摄像头进行拍照存储到sd卡中(stm32f407 using OV2640 camera to take pictures sd memory card)

本程序基于单片机实现RTC实时时钟，简单易懂(The program is based MCU RTC real time clock, easy to understand)

nokia5110源码加仿真测试,初始化液晶，按键测试静态动态显示(nokia5110 source plus simulation test, initialize the LCD, keypad test static dynamic display)

该程序是CRC校验程序，可以查看文件的校验和，这对文件本身进行校验，也可用在其它程序中检难数据正确与否(CRC procedures can view the document and check that the document itself calibration, but also can be used in other programs Frederick hard data are correct or not)

反应测试仪，测人的反应速度，精确到几百毫秒！通过按键测试！(Reaction tester, measuring people' s reaction speed, accurate to a few hundred milliseconds! Through the key test!)

仿真电话键盘拨号的电路图 C 以及HEX文件 是我的单片机考试作业(this is my master piece)

AD9851驱动程序，采用串行写入方式，STM32写入频率控制字。(AD9851 driver, using serial write mode, STM32 write frequency control word.)

SIM800C升级工具,二次开发工具，省成本的特别好用用的方案(SIM800C upgrade tool)
