PWM Glitch on the 18F, 18F, 18F, and 18F for very low duty cycles | Microchip

I never managed to get QEI module going in velocity mode. This is part of it and not complete yet. That concept started to peek through the fog eventually. Thanks a lot Bruce. The switch controls if the output is pulsed DC or cycles both ways.

First is the same thing that should be first for every datawheet pic, can you blink a led? See this post http: What I ended up with was this: I don’t have the 18F or Microchip motor control board, but this works on the 18F I can control the Freq just fine, but it makes a mess of the duty. I will definately incorporate.

PIC18F4431

I haven’t played much with this particular feature. But,i gotta some problem with the PWM Period value.

But anyhow,it’s clear enough for me to understand. Isn’t that an awesome dattasheet I mean how to find the values for. I am a bit confused.

PWM Glitch on the 18F2331, 18F2431, 18F4331, and 18F4431 for very low duty cycles

On the pin version, forget using RE3 as an input. It should be at least enough to get you started. I tried according to application note but to no avail. Hi Bruce, Sorry if i pester you a lot.

Resolution is the number of bits you dtaasheet to control the duty cycle. It’s a great uC! Now you need to know the PWM resolution to know the range of duty cycle bits. Hi, This works for me on 18F, should be the same.

Not yet at least. I use the “Hello World” out the serial port test.

datasueet I can see that there is a dependency with the PWM resolution, but I’m not sure how to manage it. Bruce, That’s a super start to a beginner like me. To work with the 18F Thank you in advance.

I’m not understanding the interaction of the frequency to the Duty.

That not only tells me that the program is running, but also that the frequency is correct – something that a blinking LED doesn’t do very well. Yeah this one is a nifty series PIC for sure. When the counter starts at 0 the output is set, when it “hits” the value of the first comparator the outputs is cleared and when the counter “hits” the value of the second compartor the PWM cycle starts over.

Subtract 1 for LowByte hserout [“D”,dec duty,”F”,dec Freq] goto Main ‘ Loop end Like I said, I’m going to have to study my own work just to understand it better, but at least it works like it is suppose to. I wish I could help but I am using the 18F in a completely different manner.
