AT89S51读写I2C总线实验之1602液晶显示 单片机对I2C总线的读写在实际的测量中有很大的作用，比如用AT24CXX系列存储实验数据等，现用AT89S51读写24C02，为了使得读出的数据能直观的表达，所以用1602液晶显示。 -AT89S51 read and write I2C bus of the 1602 experimental single-chip LCD to read and write on the I2C bus in the actual measurement has a significant role, such as the use of experimental data storage AT24CXX series, are currently using AT89S51 literacy 24C02, in order to make read out the expression of visual data, so use 1602 liquid crystal display.

一个单片机的按键程序。没有使用延时。但是使用其他的方式来达到了延时的目的。-A single-chip key procedures. Do not use the delay. However, the use of other means to achieve the purpose of delay.

开源的嵌入式WEB服务器，运行于RAM处理器，占用的系统资源极少-revenue embedded Web server running on the processor RAM and occupies very little system resources

实现数码管的循环计数，数码管接法为共阴级接法。-To achieve the cycle count of the digital control, digital control connection for a total of Yin-class connection.

能实现功能有：显示年、月、日、星期、时、分、秒、阴历月日、温度，共21位数码管。其中星期和阴历月日能根据公历自动计算改变，到2050年之前有效。温度可以测量从-10到40℃之间的温度。还可以设定两个定时、12/24小时显示、自动亮暗切换的时间等。 电路只用了两片IC，一片M48，另外一片是74LS145，4-10译码器，来扩充端口。具体电路在下面，是PROTEUS画的，给个图片做参考-To achieve functions: Display year, month, day, week, hour, minute, second, lunar month, the temperature, a total of 21 digital tube. One week and the lunar month on the Gregorian calendar automatically calculated based on changes effective prior to 2050. Can measure temperatures from-10 to 40 ℃ temperature between. Also can set two time, 12/24 hour display, automatic light switch dark time. Circuit used for only 2 IC, an M48, the other is a 74LS145 ,4-10 decoder to expand the port. Specific circuit in the following is the PROTEUS painting, a reference to a picture

51的一些很有用的子程序 很好的 建议拥有-51 some very useful subprogram has a very good suggestion

主要是51单片机的全套应用及其程序源代码-Is a complete set of 51 single-chip applications

使用AVR单片机控制的温控与定时,时间从0至99小时99分99秒,温度从-55度到99度.-AVR single-chip microcomputer to control the use of temperature control and timing, the time from 0-99 hours 99 minutes 99 seconds, temperature from-55 degrees to 99 degrees.
