Hai...

Is there any way to generate 6 PWMs with different frequencies using LPC1751?
I don't need to change the duty cycle. I just need to have independent frequencies in each channel.

AFAIR, you may generate one PWM frequency in hardware using PWM and 3 using MCPWM. If two more are needed, you can do it in software using two other timers. No problem if you don't require extremely small jitter.

Ok, I agree with that.

But any simple method to generate 6 PWMs with different frequencies in software?
I need frequency below 5kHz only.
