RS485通信的源代码，可进行两个系统之间信号的传递，介绍其编程规则(RS485 communications source code, can be passed between the two signal systems, introduces its programming rules)

说明：  读写SD卡的头文件，MMC，不含fat文件系统。(Read and write SD card.)

计算太阳位置，通过公式！用单片机编译程序！(Calculate the position of the sun through the formula! Microcontroller compiler!)

ATMEGA48 头文件 适用于 ICCAVR7.0 有些版本没有ATMEGA48的头文件(ATMEGA48 )

单片机实例学习，可以轻松学习单片机.请大家仔细专研。(SCM instance learning, you can easily learn microcontroller. To please carefully researched.)

TCS3200传感器捕获方波频率，可以根据频率变化识别外部光源颜色(TCS3200 sensor to capture a square wave frequency, the frequency change can identify the external light source color)

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

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)

这是一个为数不多的用C语言编写的PIC12C508的RGB灯的小型控制器，交流同步信号检测，七彩跳变+七彩渐变，做LED的朋友可以参考，程序可以直接使用的；(This is a small controller RGB lights a few written by C PIC12C508, AC synchronous signal detection, colorful jump+ colorful gradient, do LED friends can reference, the program can be used directly )

扫描4X4键盘,并将键值在数码管和8个LED上显示,同时将键值通过串口或RS232端口或USB发送给PC机接收并解码来自标准键盘的基本按键的扫描码。(4X4 keypad scanning, and key in the digital tube and eight LED display, while the key through the serial port or RS232 port or a USB send the PC to receive and decode the scan code of the key from the standard keyboard.)
