Hi friends is there anyone here that has an idea of how to make pure sine wave inverter in flowcode 8 things of sine table I totally have no idea how to start and end please share anyone with an idea on how to code pure sine wave oscillator

OK my circuit worked very well but i made some changes on it and in the code too and its working fine.

But in my case what do u think should be the gate resistor value connected from MT2 of BT139 to pin 6 of MOC3021? and how do they calculate its value.

Thanks medelec35 i will be waiting for your circuit too.

Sir i have recoded my program i would like you to go through it and see if it works.I have added a small delay of 2ms right after zero crossing occured and maped my 10k pot to create a delay to the triac gate firing pulse between 1ms to 7ms.Please see if it works now.Thank you once again I LOVE LEAR...

No what i had wanted in the first place was to control the time between the zero cross and the firing pulse to the triac gate by the Random Phase Driver, THE Diac (MOC3021) signal from the PIC12F683.The bigest intention was to read the value of the 10k pot one side of it connected to +5v and the oth...

Yes please i want to learn please help me with full circuit of how its done and full code with pot regulation so that i build the circuit and test it this will be good to me.Thanks God Bless u.

Hi there please i need your help am trying to design a dimmer circuit for some microscope 12vac 3Amp Light bulb,am planing on using phase angle control.This is my circuit discription: Ac mains 220vac through two resistors 47k one on neutral side another one on live side is suplied to a bridge made o...

Hi Chipfryer27 i saw your update of my flowchat and its exactly what i wanted now I've learnt how to play around with "MOD" thanks again now am going to build it and see how it goes on a real board next I will need to know how to go about a current meter like from 0-100 or 200A

Thanks a million times Chipfryer27 i was waiting for people like you to work out my flowchat.I love learning i will go thru it when i get back home today right now am on phone.

Is there no one here to help me work on my flowchat and show me how i can display DC voltage on a 7 segiment quard display?

Yes but how to use them please help us with an example. To make things simple.

Please direct me on how to get that update or give me a direct link to the download of that update you made and do i need to pay for that update or its free?

The example in the LUT does not clearly show how to display characters for example how do i display 'OFF' on a 7seg quad display?

Tried to change FC8 component files for 7seg but notepad cannot read the files when i tried to force it its shows funny characters in notepad what can i do coz I've always whated to use custom characters on 7seg pliz help how can i change FC8 componet files do 7seg to use with LUT for custom charact...

Thanks so much Viktor but to make my understanding this better an example with a 3 digit 7 seg display would be better showing how to display voltages on it instead of an lcd.

Thanks Steve but i would love to see how its done someone download my flowchat help work it out and repost it would be even more helping and quick learning that way.Thanks once again.

Am trying to make a voltmeter ranging from 0-55v but this time using a 3digit 7seg Display,this meter has two LEDs that turn ON/OFF in an interval off two seconds,Delay obtained from Timer0 INT overflow with an offset of tmr0+=3;.This works well as desired,the only trouble am geting is displaying vo...

No I havent tried because i don't know how to do it that is why i call for your help to write it for me many people will lear n from it.Please help me write it for me.

Thanks sir for your advise, I used a transformer and I was able to read Ac up to 300 vac and the circuit was very accurate same reading with my Unit digital meter now am ready to make my voltage stabilizer it will have a low and high cut option and display both input voltage and output voltage on lc...

But i have an ac voltage stabilizer here with me that has worked for months very well but is using that second setting that i posted, i have every notes about it apart from the code so i thought i could make my own code using flowcode,But what i dont undestand now is how did that programmer make tha...

Ok then i get you a transformer is a safe way to go that i know but expensive, anyway since u recomend it can u help with a full drawn diagram on paper and the calculations in flowcode calculator on how to display Ac voltage on lcd just help with diagram with all the components and flowcode calculat...

Ok if that wont work advise me also on this second setting will it work, and if it will how do we go about the calculation to display Vin on the LCD?

Yes sir you know am looking foward to making an ac voltage stabilizer but coded in flowcode because i just find my self liking flowcode very much so in my ac volt stabilizer am looking at 130vac to 280vac to give me an out put between (200 - 250vac) so me talking about 400vac (which is 565 peak givi...
