通过一个简单例子，说明C语言对于学习单片机的重要性，有助于新手的入门.(By a simple example to illustrate the C language for learning the importance of SCM to help novice entry.)

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:

说明：  点阵显示原代码，上传的为c语言，也有原理图。(Dot matrix display of the original code, upload the c language, but also schematic.)

底层调用了PCSC的通信库Winscard，可用于PC上读卡器与智能卡的通信(It calls the underlying communication library Winscard PC can be used on a PC to communicate with the smart card reader)

可以用的飞思卡尔智能车测试程序，非常不错的(Freescale smart car test procedures can be used, very good)

stm32输出四路pwm，能完成占空比可调，频率可变化的pwm(Stm32 four road PWM output, can finish the duty ratio is adjustable, can change the PWM frequency)

说明：  用单片机实现的DS1621温度传感器，测量周边环境的温度(With MCU' s DS1621 temperature sensor to measure the temperature of the surrounding environment)

I2C总线协议应用,利用单片机中断实现可以记忆的时钟,程序自己已经调试过，绝对能用(I2C bus protocol applications, the use of the microcontroller interrupt memory clock, program debugging, and absolutely can)

51单片机控制16乘以16点阵，可以显示汉字等(51 single chip control 16 times the 16 dot matrix, you can display Chinese characters, etc.)
