Hi Demon,

Thanks for quickly reply. If you don't mind can you give me zero crossing interrupt with adjust code for MOC3021 driver?

Thanks.

Hi all,
I use picbasic pro. Now I want to make a PWM controlled battery charger with PIC16F. But I don't know how to use MOC3021 (triac drive) & INTCON hardware interrupt.


Plz anybody help...

How to setup Timer2 interrupt????????

Hi,
I design a Full bride Inverter. But I want to add feedback option to my project. I got 50Hz freq from my full bridge.
plz anyone help me!!!!!!!!!! How I add feedback to my project??????


...

I am very sorry for that. But I need this project as soon as possible.

I hope your advise is correct but unfortunately I unable to understand what you say & what you order me to change in my code....

i ALSO TRY THE FOLLOWING CODE. BUT DON'T WORKING. PROTEUS OUTPUT::::
7289

pLZ HELP ME SIR.......



ADCIN 0, VOLT
FBV = FBV + VOLT
IF FBV = FBV + 30 THEN

hello bro,
I just need help that I post. But you mean something different. I don't want to rent someone knowledge.

Multi_SPWM not suitable for Inverter project & I tested this for Inverter and the result was worst. Plz modify this Multi_SPWM software.

I unable to find something helpful from your link.

hmm.... you are right.
but from this blog (http://forum.allaboutcircuits.com/blog.php?b=512) i found that i convert to picbasic. but not working!!!!
can you solve this problem????

feedback not working!!!!!

proteus & main mikro C file : 7288



DEFINE OSE 16
ON INTERRUPT GOTO ISR

'*************************VARIABLES

i expect output from this project as picture for inverter slow pwm:::::7287

i want a pwm which as output as:
7285

but multi_spwm give me a output which as:
7286

how i will get my expected output from multi_spwm????

I hoped that is site is useful but I never get any help from this site. So this is my last post if I will not get any response I never post in this site.


Proteus File: 7283

I modified SPWM software and add a more SPWMpin but I need a variable duty cycle. (see the photo)
7281


define OSC 10
SPWMpin var PORTC.2
SPWMpin1 var PORTC.3
Include "SSPWM.INC"
...

well....
thnx....

Button subroutine work properly that u said. but problem in "up" and "down" button. Plz check proteus file. another problem is 7 segment display blanking.

I am new in Micro-controller programming. I am from Bangladesh. I am a little boy. Now I read in class 10. My hobby is programming. I start programming about 2 month ago. So, I don't know much.

I want to make a LCD Inverter. I already made a program in picbasic pro. But I could not complete the PWM part. I want 2 channel PWM output at 50Hz fixed frequency and variable voltage(Feedback)....

How make 2 PWM output at 50Hz fixed frequency in PIC16F72 with feedback in picbasic pro?
