Thanks allot medelec35 its educative to always have you around and that is why its always good to ask the professionals before u act now i have to remake the PCB with an external oscillator this one with internal oscillator was one second behind when i was testing it this went on increasing to 2 sec...

Hi every one,is it advisable to use internal oscillator while designing a real time clock? my issue is,i wanted to control some device and turn it off when set hours have reached so what i did i got my PIC16f886, set the internal frequency to 8MHZ, enabled Timer2 int with Prescaler Rate= 1:16, Posts...

Is there a way of disabling and enabling Timer2 of PIC16F628A in a Whle1 Loop sothat it starts its timing at any point i desire and stoped at any point in code that i desire? If yes please help show me how.I really need this stoping and enabling sothat i dont miss out some seconds when the start but...

Wawoo!!! thanks medelec35 i really like people who teach the simple way for everyone to understand and thanks for not getting tired of many questions asked.You know when you look at the Arduino many sketches are written out there and people can just download and edit as they require with flowcode we...

Thank you very much medelec35 for the help but i would like to learn why do you use Rollover Value as 250 and not 255.

medelec35 please help look at my FC Prog and see how you can modify it to work better.Here am timing for 15 seconds and then multiply Count by 4 to give me Heart bpm.

Am going to use a pullup resistor 10k on INT pin my question is how do i pulldown INT pin inorder to cause the External interrupt,in response to the digital siginal,can i use the digital output siginal to drive an npn transistor which in turn pullsdown the INT pin in order to cause the interrupt and...

Thanks medelec35 ,i think your idear will work.Can i use a transistor to pull down INT pin once a digtal siginal is detected?

250mS x 4 wont that be beats per second instead of beats per minute?

No i donot have it because i want to first get the FC program written then i make the PCB and try it out but i want to use exactly the same easy pulse v1.1 board together with a PIC but first before i make the PCB i need to be sure i have the Flowcode prog written.

Thanks stefan.erni sincerely speakng i have NO FC program written yet coz i don't know how to do it that is why am looking for a helper to write the FC program and we go thru it as that is the best way to learn for newbies like me.Thanks again.

Hi every one,i came across this chinese Heart beat pulse sensor known as EASY PULSE V 1.1 does any one know how we can interface it with a pic in flowcode to show the Heart bpm On a 16x2 LCD.Here is the website you can find good information about it. http://embedded-lab.com/blog/easy-pulse-version-1...

Thank you very much chipfryer27 for showing me this trick, i didn't think about this trick and went on repeating the same code taking up allot of my MCU space, but with your trick i can now build on it to come up with different Text scrolling as i desire. This is exactly what i was looking for thank...

Yes Medelec35 thanks for your work it has been so helpfull, ive seen yours and it works just the same as mine but correct me if am wrong coz one time i used the print Number comand and it had trouble printing Floating point numbers thats why i decided to use strings through out.

Ok thanks Martin for that correction I edited it and i think now its working

Hi Medelec35 and thanks for your quick response,ive added an LCD in your flow-chat so that i could see what is going on but the result i got is not exactly what am looking for yours goes from 30 t0 10 the goes to something like 70. But what i want is for temp ref to be adjustable from 0 to 30 and ba...

Thanks Medelec35 for all your help in this project it was successful.

Hi guys am happy to ask as many questions as i can and get as much info as i can so that in future i can write my projects with no more questions asked.Thanks to all of you guys that help me out.My next question is, how do we increase and decrease a variable with one button to increase it when press...

Thanks DCW yes i know that guy Tahmid i my self been using him for some time and he has been so helpful in my smp inverter research and about flowcode i think it cant translate all the C code directly into flow-chat maybe Benj can come in and help us out. My only worry is how do we get Benj visit Ta...

Thanks Benj yes am using "ScrollDisplay" but would you please help download my flowchat edit it and re-upload your edited flowchat, that way will be easy for me to learn the trick and get to know clearly what u are trying to say.Pease help.

Thanks Benj but Guys, i totally don't know how to do this which is why am requesting for a complete project if that is possible then discus where i get lost from which i think is the best way to learn especially for slow learners like me thanks guys.

Hi there please look at my flow chat in the created macros and advise me on how to write a simple code to scroll the text on the LCD (the simple way) if there happen to be any.I need a way to write a small flow chat to do the same text scrolling instead of repeating the same code many times like i'v...

Thanks Benj but is this possible for you to provide this as a full complete spwm dc- ac inverter project with feed back say by having different sets of sine table with each having may be 32 values for different duty percentage values may be starting at lower duty of may be 65 percent when the invert...

Guys how to obtain a sine table of 32 values in flowcode? Please help really need help on this and how to implement SPWM inverter.

Thanks STibor but i need a live example for slow learners.
