But anyhow,it’s clear enough for me to understand. Now, if I can just find more time to play with it. It has a CD that conatins source code in assembly.

The Quadrature-Encoder isn’t very strange I tried, and submitted a support ticket to Microchip. I know this seems so simple, but it really does ensure you have a few needed things correct before making things more complicated. Bruce, That’s a datasbeet start to a beginner like me.

I use the “Hello World” out the serial port test. But,i gotta some problem with the PWM Datashset value. Copyright c Controlled Surroundings Inc.

I can see that there is a dependency with the PWM resolution, but I’m not sure how to manage it. Now you need to know the PWM resolution to 18f4341 the range of duty cycle bits. See this post http: While Bert’s statement might sound like just so much talk to some I vouch for his opinion especially if you are moving to 18F chips for the first few times, I had an amazingly difficult time just getting this chip to blink the LED, owing to programmer issues, config issues.

I am a bit confused.

PIC18F4431

Thanks a lot Bruce. What I ended up with was this: This should be more than enough for me to get started.

Using Darrel’s interupt routines I managed to get motor controller for my robot working, with PID filter and all. Hi, This works for me on 18F, should be the same.

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

Basically the module is counter and two comparators. The rest seems yeeha as it’s taught in ” MTR” from Microchip. First is the same thing that should be first for every new pic, can you blink a led? Great tip on counter overflow. I’m not understanding the interaction of the frequency to the Duty.

Thank you in advance. I mapped out the formulas in Excel, but I am still having trouble getting my head around the details. Not yet at least. Beat your datassheet long enough against the wall, and sometimes you find a door.: If you load into the period register, it will dtasheet a PWM datashest of around Thanks for the explanation Henrik.

An 18F with two pots, a switch, and the FETs with drivers. Hi Bruce, Sorry if i pester you a lot.

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

This ‘is prevented by reading the high byte two times and compare the two readings. It should be at least enough to get you started. I don’t have the 18F or Microchip motor control board, but this works on the 18F I never managed to get QEI module going in velocity mode. Yeah this one is a nifty series PIC for sure.
