This is one hell of a video I have never spent so much time watching it. Good tutorial !!!

@Thundertronics Месяц назад

Glad you liked it!

welcome bro.

@smartsamirul5499 2 года назад

can you help to learn how spwm signal 50hz for sine wave inverter work perfectly ?

@RiddimDubstep Год назад

I can't seem to wrap my head around where the first interrupt happens. You initialised the CCP1, the Timer1 but I can't see what triggers the first interrupt, like where did you set the value in the CCP to be compared to the tickrate of the Timer1 to trigger the interrupt when Compare = Tickrate.

@Thundertronics Год назад

unfortunately, it was a long time ago and I don't remember what exactly i did. you can just see the code and try to understand it.

@RiddimDubstep Год назад

@@Thundertronics I think I know. First interrupt triggers because Timer1’s ADRESH and ADRESL are empty. You can also set a value in ADRESH and ADRESL then Timer1 will trigger the interrupt. Therefore you don’t even need CCP

great explanation

Glad you think so!

The code works well and i have generated two pwm signal at ccp1 and ccp2 at 50hz but my problem is that i can't get to off ccp2 for ccp1 and vise versa, so that they wont be working at the same time. Am using it to power my two side mosfets in an inverter. PLS HELP ME

Thank you.

How do i use ccp1 and ccp2 having the same frequency

@naiiverio 8 лет назад

i clicked the "MPlab X project file (code): mega.nz/#!SMpwEDST!VsT6uPJdYp..." part of your attachment but it says it needs a decryption key. pls help. tnx

+Nai Senpai I am sorry! here is the fully working link: mega.nz/#!SMpwEDST!VsT6uPJdYpIUbnEuIXLudGUtsAI45ThHi49N9umErOE I modified the link in the description too.

@wajahatali3981 6 лет назад

which Software is this?..integrated with MPlab. Please reply ASAP.

@Thundertronics 6 лет назад

I have used Proteus for simulation and MPLab X for programming.

@@What-tp8gs لا أعلم أخي مع الأسف. الثري-فيز صعب في الإلكترونيات ولا أدري كيف أساعدك. لكن لو لديك الدارة وتريد برمجة متحكم وقتها استعمل الأردوينو كونه سهل

@wajahatali3981 6 лет назад

One more thing . The clock frequency you used is 20MHz. Is it Exeternal? Please reply

@Thundertronics 6 лет назад

yes

@wajahatali3981 6 лет назад

But In your lecture You said you are using 20MHz internal . There is no internal Oscillator in PIC16f877a

@Thundertronics 6 лет назад

I definitely used an external one. the XTAL command is for it not for internal one.

@amruthuramesh3307 6 лет назад

Sir can I make two pwm pulses from RC1 and RC2 with same frequency but two different Duty Cycles. With this same concept of PWM generation

@paul_reddy 2 года назад

Yes you can , use two for loop with some loop value same or different ....as on and off of bit, but high resolution you may not achieve.

@ravindratajane4001 6 лет назад

Sir... Please make video on software spwm using pic microcontroller 16f72 or 16f877a . Please I'm waiting,

@Ordinary._.Original Год назад

in 12:42 its 819 us not 81.9?

@Thundertronics 8 месяцев назад

thanks for correction

@aasimzia9781 7 лет назад

does not work on pic18f452. why?

@Thundertronics 7 лет назад

I didn't try it on PIC18. However, I demonstrated the concept which you can do it for your own PIC. Your PIC may have other settings for the timers and CCP modules. Read the datasheet and try to mimic what I did here using your settings. Good luck!

@ravindratajane4001 6 лет назад

Thank you. Very helpful... Dear Sir, Please make video on spwm using pic microcontroller. I'm face much critical to write a code for sinewave solar power ups using pic microcontroller ie. 16f72 or 16f877a. Please help me.
