【正文】 crocontroller, LED display circuit, and the tune posed of the circuit when the button. In the SCM choice I used the AT89C52 microcontroller, which is suitable for many of the more plex control applications. Monitor the use of two 7SEGMPX8CA and a 7SEGMPX4CA. 7SEGMPX8CA is a total of eightyang diode display, 7SEGMPX4CA is a total of fouryang diode display. In order to more easily control the three monitors, I use three 74HC164 to drive. 74HC164 is an 8bit edgetriggered shift register, serial input data, and parallel output. The software includes calendar program, time to adjust procedures, turn the lunar calendar programs, display programs. Programs written in assembly language used in order to more easily adjust the time and the realization of the lunar calendar display. All programming is plete, the wave software debugging, make sure that no problems, in the Proteus software within a microcontroller embedded in the simulation. The final overall the teacher to help students, as well as their own efforts to plete the design of the electronic calendar.
