Single-chip Computer Simulation

1. Open the Keil Software

2. Create text1

3. input the program (*** see Appendix 1)

4. Save it as a. c file

5. Create a project

6. Select Atmel-> AT89C51.

7. Right-click source group 1 of the new project and choose add file to Group 1.

8. Right-click the new project name> Option> output> and select create a. HEX file.

9. Compile to obtain the. HEX file;

 

1. Open protues

2. Draw a picture as follows:

3. Double-click the single-chip microcomputer. In the displayed dialog box, add the generated. HEX file to the program file.

4. debug-> exrcute
