First exercise using Keil uVision 4 for 8051 micro-controller

It's easy to create a 8051 project using Keil 8051 Development Tools, uVision 4. You can also debug the program using the build-in simulator.

- New a uVision Project in uVision 4 IDE.


- Select project location and file name.


- Select 8051 (all Variants) under Generic in Data base, and click OK.


- Accept Copy Standard 8051 Startup Code to Project Folder and Add File to Project. The IDE will copy STARTUP.A51 file for you.


- Right click th project "Target1" and select Options for Target 'Target1'...


- Select Small Memory Model and Small Code Rom Size, and click OK.


- Click File -> New... to creat your main.c

- Type in the program, and save it as main.c.

#include <reg51.h>

void DummyDelay();

void main(void){
 char c = 0x00;
 while(1){
  P1 = c++;
  DummyDelay();
 }
 
}

void DummyDelay(){
 unsigned char i, j;

 for(i = 0; i < 0xFF; i++){
  for(j = 0; j < 0xFF; j++){
  }
 }
}

- Right click Source Group 1 under Target1 in Project, and Add Files to Group 'Source Group 1'...


- Browse to select the main.c just created.


- Click Project to Build Target.


- After finished without Errors. Click Debug and Start/Stop Debug Session.


- Click Peripherals -> I/O - Ports -> Port 1 to open the Parallel Port 1 monitor window.



- Finally click on the Run icon, or F5, to run the program in simulated mode. You can see the Port 1 Bits in Parallel Port 1 monitor change while the program running.


- Click Debug and Start/Stop Debug Session, or Ctrl-F5 to exit and back to edit mode.
