1984-1993模糊 C 源代码竞赛.zip 非常的好,不过这是DOS格式,要用UE去打开.-1984-1993 Fuzzy C source code for race. Zip very good, But it is the DOS format, we should open the UE.

c8051f020的应用程序,主要为对ADC0的应用,使用其内置的温度传感器读取其片内温度值,并可以设置模拟输入口检测电压值-C8051F020 applications, mainly for ADC0 applications, using its built-in temperature sensor to read the chip temperature, and can set the analog input voltage value detection

这个是实时时钟芯片DS1302的驱动程序，采用c51编写，编程时只需要修改一下SCL,IO,RST的引脚定义即可，经过测试，完全好用-This is a real-time clock chip DS1302 driver, using C51 preparation, programming, only need to modify about SCL, IO, RST pin can be defined, tested and fully use

水位仪代码，配合水位传感器使用，可以是malay，可以使p+f型编码器-Miriam level code, with the use of the water level sensor, which can be malay, can p+ f-type encoder

ＡＤＣ０８０４程序设计是和ＡＤＣ０８０８相似-ADC0804 and ADC0808 program design is similar to

AVR俄罗斯方块程序:游戏区是18*15格，3*3点阵一格，右边有下一个图形显示和所消行数的显示

7通道AD转换程序，实现多通道数据采集系统方案-7-channel AD conversion process, realize multi-channel data acquisition system program

lcd12864 的串行驱动程序，于keil uvision 开发平台。-lcd12864 serial driver, in keil uvision development platform.

spi 翻译资料 7.2 SPI总线 SD卡信道由指令和数据位（起始位和结束位）组成，SPI信道由字节定向。 每一个指令或数据块由8位的字节和CS标志构成。类似SD卡协议, SPI通讯由 指令、响应和数据组成。全部的主机与SD卡之间的通信由主机控制。主机执行 每一跟CS标志为低的总线-spi Translation 7.2 SPI bus data channel from the SD card command and data bit (start bit and end bit) component, SPI channel directed by byte. Every command or data block from 8-bit bytes and CS constitute signs. SD card similar to the agreement, SPI communications from command, response and data components. All of the host and the communications between the SD card by the host control. Each host implementation with CS low marks for bus

使用串口通信和汇编控制单个步进电机，串口部分可以使用串口调试助手-The use of serial communication and the compilation of a single stepper motor control, serial port can use the serial debug some assistants
