18 khz wave

Tell me how to generate the 18KHz square wave using 8051 microcontroller
 

What about using a DAC with you microcontroller, this way you can generate a lot of waveforms.

I am making a project in which I want to generate different waveforms using the PC and interfacing the DAC with the parallel port

Why do you use Timer 0 interrupt ???It's is very easy to do.
In the KeilC complier, there is the good example for U !
You can download the demo version in the web (2K limited)
www.Keil.com
and then setup to see the example.
Good luck for U !
