Hi,

Forget about the Simulink. Pls advise me how to create a single event which can produce a single pulse with the device if possible.

Thanks

Sure, one of our PWM experts will assist you with the same.

Joey,

How do you want the pulse, or pulses, spaced?

Are the pulses a one time event, or will they happen with a regular period?

Are you planning to have a fixed period? 

If you are having pulses with a reoccurring period, its best to use a PWM. It is OK to have a variable frequency too, this can be easily done with the PWM. Its typically best to have one pulse per PWM period, having more than one pulse is difficult. Having less than one pulse per PWM period is OK, so if you need multiple pulse, it may be best to increase your PWM's period.

if the pulses are not reoccurring we can talk about methods of doing that, which could be through a GPIO or a PWM that will be reconfigured in its ISR.

Hi, Cody

Thanks for your reply.

I hope the pulse is one time event. Pls advise me how to realise it.

Thanks

Hi, 

Anyone can help with this issue?

Please configure the PWM as desired. You can use the CMPx events to determine the width of your pulse and your PWM period can be any number longer than your pulse width.

Inside of the PWM's Period ISR disable your CMPx events and set them to drive your PWM output equal to zero or whatever your preferred safe state is.

If you don't want to use the PWM module this can be done with GPIO toggles and CPU timers.

Cody
