51系列单片机的数码管试验的C语言程序。-51 Series single-chip digital test tube C language program.

如何做SPI采用P89V51RD2  ；串行外设接口（SPI）之间的一个两RD2主奴隶，并在终端使用UART发送的数据输出。

this is sleep and time function, you can have a look. it is programming by c language, the gold of this program is achieve   1.how to use time functions to measure time 2. to understand program execution in a multi-task environment 3. to understand the concept of time drift

使用ds18b20编写的数字温度计程序，同时用LCD显示，此LCD价格便宜，使用方便-Using the digital thermometer ds18b20 written procedures, with the LCD display, this LCD are cheap, easy to use

每次开机都将次数加1 并存储到EEPROM。这样就能直观的看到机器的使用次数。用P1口 LED做为显示，次数大于256是将溢出，按复位模拟开机 或者直接通过开关开机。-Each boot will add a number of times and stored in EEPROM. This will be able to see the intuitive usage of the machine. As with the P1 port LED display, frequency is greater than 256 is the overflow, according to reset the boot, or directly through the analog switch boot.
