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.
