pwm example (by Chris R)

Hi I must say you ladder program works really well thanks for letting us use it im using the atmega16.

I was wondering if you had a pwm example as I am having difficulty working it out.

Thanks

Chris

See the example. The output frequency is always 1.00 kHz, and the duty cycle is either 50% or 75%, depending on the state of Xin.

Can we change the PWM frequency on the fly (by Ranjit)

I want to change the PWM frequency on some condition.
How can I do it.
For example if input is open PWM frequency will be 1khz with 50% duty/
if the same input in close PWM frequency will be 500hz with 50% duty.

PWM fundamentals and reasons to be joyful (by Ziggy)

Ranjit,

Purpose of PWM output is to provide ( generally speaking ) a variable DC signal.
Maintaining same duty cycle but altering base frequency will not alter average DC value.

Whay do You require PWM facility?

pwm Para brushless (by Mariano)

Estimados,

necesito controlar un speed control de un motor brushless con un PIC16f628, probé con LDMICRO Y NO PUEDE HACER CICLOS MENORES A 1ms
żdepende del micro o programa?

desde ya agradezco toda ayuda

Atte

Ldmicro is too slow for generating brushless motor pwm signals.

PWM 08 Output (by Tran viet Dung)

Hi all, How to Using more than one out put PWM (example: have 08 PWM out put on AVR Atmega328P). Thank you so much
