#90310 - PWM generation using microcontroller |
Hello Friends,
I intend to generate audio tone of 500Hz,250Hz and 1kHz,using a microcontroller. I have chosen Philips 89V51RD2BN for this application. I am using assembly language for the programming the IC. I am able to generate audio of different frequencies but not what i intend to generate. Will appreciate your help :) Sushil. |

| Freq. or duty cycle or both ? | 01/01/70 00:00 | |
| PWM? | 01/01/70 00:00 | |
| Amplitude? | 01/01/70 00:00 | |

| Not at all! | 01/01/70 00:00 | |
| Varying both frequency and duty cycle. | 01/01/70 00:00 | |
| possibly this way | 01/01/70 00:00 | |
| thanxs but.................. | 01/01/70 00:00 | |
| PWM and frequency | 01/01/70 00:00 | |
| This thread is fuzzy because | 01/01/70 00:00 | |
Both frequency and amplitude? Yes! | 01/01/70 00:00 |
