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.

奉上刚做好的测温小制作--基于DS18B20传感器 今个学期刚学了单片机，学期末的时候老师要求每个人都做个有关单片机应用的小制作，而我的作品就是这个。DS18B20挺好用的，功能很强（我用到的只是最简单的）。可惜现在没时间（要考试！），等下吧，考完后我再努力将这个小制作的功能加强，特别是想做到能自动识别传感器ID号的功能。 我知道有很多人都对DS18B20很感兴趣，借此奉上源代码，实物我已经做好了，测温很稳定。希望对大家有帮助。-Thermometry of small production-- DS18B20 sensor based on this semester just learning the microcontroller, the end of the teacher asked each one of the SCM application to be a small production, and I was in the works. DS18B20 very good use, and highly functional (I use only the most simple). Unfortunately, there is no time (to test!) , And so are you, I again after taking the efforts of the small production of functional strengthened, in particular to achieve recognition sensor can automatically ID function. I know that many people are very interested in right DS18B20 to enclose the source code, in-kind I have done well, very stable temperature measurement. We want to help.
