Help Appriciated.......PIC AC Volt meter

[manojsoorya]

I have a code for a PIC AC Volt meter. I need the hex file from this code.... I cant compale, i get some errror messages..... Some one please help me.............and this is the code..

[sahu]

which compiler use ?

 

[manojsoorya]

which compiler use ?

Which is the correct compiler for PIC Chips ?

I wouldn't hook that circuit up to 240VAC. It's a very poor and possibly lethal design.

Agreed!!! I wouldn't either...


As for the compiler it looks like MikroC...

Doesn't change it's a poor and probably lethal design. Are those ICs stuck in styrofoam? Seriously, build something that's not directly attached to 220VAC.

 

[ronsimpson]

A meter like this should be in a plastic box, double insulated, so the user won't get killed.

what do you mean?

There not anything stopping you from getting mains voltage to the pic if a part goes bad
starters a small fuse on the testing side would be nice. Then the limt resistor changed from one to two of them so if one blows your still
alive to smell the smoke and unhook the thing.

 

[blueroomelectronics]

If you need an AC voltmeter why not go buy one. They're cheap enough and are less likely to kill you. Also how do you plan to calibrate your voltmeter?

Hi ronsimpson

Thank you for your suggession... But I try to make another one exact like this.... So I need to try to test purpuse only. After I Build, I can enclose whole circuit in a plastic case.

Thank you so much.
