Hi ravi,

hai friends
i just started doing projects with 8051, i got the code from web.
but how can i dump the code
how can i simulate and verify the operation?
plz help me
i m using keil

use proteus for simulation of ur code and u can also use keil debugger

Im agree with majoka. Proteus is very good simulator.
In keil, if your application is just a counter interrupt, a keil debuger is enough.
