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. Isn’t that an awesome controller? It should be at least enough to get you started.

Thanks for your code although its in assembly. An 18F with two pots, a switch, and the FETs with drivers. 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 haven’t played much with this particular feature. For PWM resolution use the equation below. It has a CD that conatins source code in assembly. On the pin version, forget using RE3 as an input. Here is my code. The switch controls if the output is pulsed DC or cycles both ways.

I don’t have the 18F or Microchip motor control board, but this works dahasheet the 18F I never managed to get QEI module going in velocity mode. I’m not understanding the interaction of the frequency to the Duty.

I’m using the 18F too. Thank you in advance. Equation ‘as shown in the data sheet’ doesn’t produce the same figures for PWM resolution shown in Table I was wondering if someone has done same thing in pic basic dxtasheet.

I tried according to application note but to no avail. Beat your head long dataasheet against the wall, and sometimes you find a door.: I will definately incorporate. I know this seems so simple, but it really does ensure you have a few needed things correct before making things more complicated. Great tip on counter overflow.

Well,it drive me crazy to know about it. I adtasheet a few attempts to begin with but could never quite figure it out so I went for my own velocity calcs newPos-oldPos. I don’t fully understand how to plan for it, but I did figure out a relationship in my application and kind of applied a brute force solution.

I can see that there is 18f44311 dependency with the PWM resolution, but I’m not sure how to manage it. I use the “Hello World” out the serial port test. This is part of it and not complete yet. See this post http: I mapped out dxtasheet formulas in Excel, but I am still having trouble getting my head around the details. Yeah this one is a nifty series PIC for sure. I mean how to find the values for. Could you guide me how to do this.

Not the PWM frequency.
