#105299 - PWM P89LPC952 Responding to: ???'s previous message |
Hello,
Thanks for the answer. The P89LPC952 was already chosen for the project and I have been working on a half completed project from 5th Dec 2005.So I was not the person who selected the micro-controller.Now I neet to run the beeper using a 4kHz, 3.3(P-P)V square wave PWM output and get it going!!! I need a way to igure out how the frequency can be varied. I tried changing the TH1 and TH0 values but they would change the duty cycle and not the frequency of the square-waveform.I need help. |
