if there is no dependency on the value of these constant vars that MUST be computed in runtime-then by all means declare them CONSTS.
I don't think if there can be any tool for this job.

I am Producing a software PWM that get's the freq and duty from operator and produce the desired pulse.

so I calculate about 8 variable ( all long ) and pass it to the ISR.
so they calculate one t ...

Well , my problem with this circuit was : increasing y with the increasing of x (and vice versa ). I never understand what was the problem but the problem solved when I change the circuit.
I watched ...

No.

Any variable is going to 'stand on RAM', even one that was passed (you would need to store it in the interrupt function, and since these can occur anywhere all variables used in interrupt funct ...

Dear PICoHolic,
Hi,
were you able to use this program completely?
for example could you draw any picture or write anything you want every where in your LCD?
I have used another circuit that I have ...

Hi all
is there any way for passing variables to the Interrupt functions ?
I have to use public vars for this purpose , but this way my program has became so complicated . and also variables witch a ...

Hello Dear Shahryar,
could you explain a little about the IC?
it was not clear from the datasheet that it's just for LED driving or for all-purpose PWM usage.
how much is this chip output_freq (by ...

If you can, post a small program that has the problem. Might be something 'silly' that you can't see because you've stared at it foe hours !
Also post compiler version.

Thank you temtron ...

Thanks for your reply.
I have tested it before and it worked for me. But I have some halts in program execution and I guess this could be related. Also halts decreased when I delete these values. So ...

hi all
is it possible to give initial value to the global variables in their declarations/definitions ?
for example:
unsigned int16 minimum=12;
thanks

thanks a lot

The FRAM (in I2C versions)

could you please introduce a part number of these FRAMs ?

All you do is have enough capacitance on the supply rail

I have many LEDs on the circuit so I think I s ...

thanks for your help.

the MCU I'm using is "PIC16f877A" .
I may change it to "PIC18f452" if it has the ability.

Try FRAM. FRAM delay-less writes eliminate those issu ...

hello all.
I'm writing a program for controlling a triac component.(a variable dc power supply).and I've used a zero cross circuit for understanding beginning of AC input signal. and I have connect t ...
