Updating HPWM frequently, safe?

That's just his little way of saying "I don't Know, go read the datasheet or something."<hr>
HTH,

Hi, Darrel ,

I do not know if you're right here ...

The fact is I used HPWM without pain for years ... but NOT aboard any '683
and it REALLY seems there's a HARDWARE ( say CCP functionning ) issue.

The µChip section Skimask pointed at shows " PMW module *might* be disabled before changing the dutycycle ". I read some Other Pics Datasheets and this GREY section didn't appear elsewhere ...

IF I'm right, this "funny feature" happens whatever you use, assembler or Basic (!) ... The way HPWM command works doesn't matter here !!!

So, a ( Which other Basic do you think to ??? .... mmmmmh ? ) HPWM_UPDATE command wouldn't solve the question !!!

µChip clearly says : Changing the dutycycle while PWM running (and only dutycycle is enough ) will produce unwanted effects ...

The only way I see to keep ( is it really necessary ??? Good Q.) a "neat" PWM output would be to switch between HPWM, to the last produced fixed freq. and duty, soft PWM ... while disabling CCP, changing Dutycycle and re-enabling the CCP.

Quite a funny little sub to write, no ???


Back to our Friend Skimask ... I really do not know ... if he really doesn't know the "what is wrong".

I'm Ok ... this is not giving the solution, nor ... BUT ... His first answer could have been " Won't work with the '683 ( FINAL POINT )"


Would be kind to leave guns, knives, scissors and umbrellas out before entering the saloon ... just a thought.
