....how can i put lookup table data on pwm duty? Do I need to change hardware? For example add lpf filter?

hi...i don't know anything about spwm...what is it? how can i generate spwm with pic16f series?
what is lookup table??
tnx

Generally on IC type modules, you don't read the timer. You read the capture register. The whole point of these modules is that they record the timer value when triggered, then interrupt. The compiler ...

It'd help if you told us which PIC you're using !
I can't tell if that code is correct let alone do what you want.

Obvious place to start would be trying 1 PWM input, then 2,then more...

You ...

hi buddies...i have 6 pwm channel with 1 khz freq and 6 input capture(icx)...i want to capture 6 channel wave with timer3 but Interferometry between output...how can i capture waves One by one with on ...

Your chip does not have a comparator.
Probably explains why you are having trouble!.....

If you look, there is no section in the data sheet actually entitled 'comparator'. Unfortunately the word ' ...

hi buddies.....i want to use dspic33fj256gp506 comparator with external refrence voltage..how to do it..anybody can help me? example source?

tnx alot

Good.

One other thing often not realised, is just how high the instantaneous currents can be on things that are switching. Even the little PIC may only draw a few mA 'average', but at the actual ...

Then there is the physical layout of the tracks. I like to think of the electricity, like currents in the sea, or a river. Go and look at a river sometime, and notice how behind the legs of a brid ...

tnx alot my friend ..temtronic..newguy..Ttelmah

Today I did an experiment. To be able to understand EMI and the effect it has on circuit, I use aluminum foil between 2 pcbs and see interesting res ...

Have you tried running just one of the other 3 processors as well? Does that make a difference in the other 3 (idle) processors and their behaviour?

It's entirely possible that the processor that' ...

tnx for reply my friends..I totally agree with your comments but Many things has me confusing..

1.from 4 pic in pcb always one micro work very well..why?..if EMI noise Involved 3 pic and Causes fre ...

Think about it.
You don't have four micros in 'the same condition'. The other three are _idle_. Their drives are off, with no load connections actually being enabled to the motors. Very different pot ...

One thing I'm very suspicious of. Are the four connectors on the centre of the edges of the board, for ICD/programming?. What pull-ups are you using on the MCLR lines?. Do you have a jumper for t ...

How many layers on your PCB?

2 layer..The first layer for dsp chip and second layer for the mosfet
