51读写24C16的源程序.....用IO口模拟I2C

用C51编[写的按键运用程序,已在产品中运用-C51KEY

触摸屏设计开发详细资料以及参看设计电路板图-Touch-screen design and development of detailed information and refer to design the circuit board diagram

这是点阵程序 个人认为先学点阵再学lcd比较好 p0 p2分别接16*16点阵的高八位和低八位(纵向取模) p3口低四位接4-16线译码器（74ls154）译码器低电平为列选 消除鬼影的方法：-This is the program individual lattice lattice before you think lcd is better to learn p0 p2, respectively, then 16* 16 lattice of high and low 8 8 (vertical modulus) p3 I received a low four 4-16 Line Decoder browser (74ls154) low-level decoder for the elimination of ghosting out the election approaches:

串口通信 单片机程序 isp在线下载功能-Single-chip serial communication program isp online download function

I2C通信的程序，用VHDL写的，可用于FPGA和单片机的通讯。-I2C communication procedures, written with VHDL, FPGA and MCU can be used for communications.

串口调试程序，接收FLOAT的4BYTE并解析显示，常用于单片机开发-Serial port debugger, receive FLOAT(4BYTE)and parse it to show that commonly used in MCU development

本例采用89C52, 晶振为11.0592MHZ，关于如何编制音乐代码, 其实十分简单,各位可以看以下代码.频率常数即音乐术语中的音调,而节拍常数即音乐术语中的多少拍 所以拿出谱子, 试探编吧!-Example use of the 89C52, crystal for 11.0592MHZ, on how to prepare music code, is actually very simple, you can see the following code. Frequency that is constant in terms of tonal music, and the constant beat of music terminology that is how much of the shoot so come up with music score , test made it!

其中包含了单片机与5045芯片的通信，读出字节，写入字节！还有单片机的内部时钟定时器，中断等操作！-Which includes 5045 single-chip and chip communications, read byte, write byte! There are single-chip" s internal clock timer, interrupt operation, etc.!

用C51实现模糊控制器的软件设计,51系列单片机接口.定时器中断等。-C51 realize the fuzzy controller with the software design, 51 Series MCU Interface. Timer interruption.

休眠模式下的AD转换，高速，10位，更低功耗-Hibernation mode AD conversion, high-speed, 10, lower power consumption
