datashdet This ‘is prevented by reading the high byte two times and compare the two readings. I mean how to find the values for. Yeah this one is a nifty series PIC for sure.

Now, if I can just find more time to play with it. I use the datasheft World” out the serial port test. But,i gotta some problem with the PWM Period value. To work with the 18F I mean it’s really worth to understand this special function micro which i will face the App soon or later.

Resolution is the number of bits you have to control the duty cycle.

Bruce, That’s a super start to a beginner like me. One Pot is for Frequency, the other is for Duty.

First is the same thing that should be first for every new pic, can you blink a led? I’m trying to make a generic H-bridge for low frequencies and keep running into the wall. What I ended up with was this: I tried, and submitted a support ticket to Microchip. MOVFF is move file to file. Using Darrel’s interupt routines I managed to get motor controller for my robot working, with PID filter and all. Now you need to know the PWM resolution to know the range of duty cycle bits.

The switch controls if the output is pulsed DC or cycles both ways. Not the PWM frequency.

CCS :: View topic – Can’t setup_spi2(mode) for Pic18f ?

The fact that my frequency darasheet duty had to be changeable made it a bit more confusing for me. Thanks a lot Bruce. Beat your head long enough against the wall, and sometimes you find a door.: I haven’t played much with this particular feature.

If you load into the dxtasheet register, it will generate a PWM frequency of around It has a CD that conatins source code in assembly. I wish I could help but I am using the 18F in a completely different manner.

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

Could you guide me how to do this. Thanks dqtasheet your code although its in assembly. I know this seems so simple, but it really does ensure you have a few needed things correct before making things more complicated.

See this post http: On the pin version, forget using RE3 as an input. I can see that there is a dependency with the PWM resolution, but I’m not sure how to manage it. Here is my code. For PWM resolution use the equation below. An 18F with two pots, a switch, and the FETs with drivers.

datasheft This is part of it and not complete yet. The rest seems yeeha as it’s taught in ” MTR” from Microchip. 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. I was wondering if someone has done same thing in pic basic i.
