Simple timer design

Learning Objectives:

1. Can say the structure and working principle of LED display;

2. Can describe the characteristics of the two display modes of LED display;

3. Can design a 60S timer and can debug the simulation operation;

4. The finished work will be detected and troubleshooting using a multimeter.

Recommended hours: 10 hours

Learning Process:

　1. Read the book by checking the information and draw the structural principle diagram of the LED display　　　

2. Write out the program segments of the LED static display mode and dynamic display mode through group discussion

3. Consult the information, use your brain, and design the 60S timer under the guidance of the teacher

(1) Hardware circuit design:

(2) Software programming:

(3) Write out the steps to simulate the above-mentioned designed program with Keil software

4. List the number of required hardware in small groups, and weld, and finally write the HEX file generated by the source program compilation to the microcontroller for debugging and running;
