Opps! try this one i zipped up the wrong one

good luck wizpiz

Thanks for the help Jaspaa... Some of the math routines on piclist works and some dont work.... also when you multiply a 16 bit number you end up with a 32 bit result... I guess that would work but I would need to use a 32 bit binary to bcd converter routine.... so, maybe I'll give that a try.... I was trying to multiply to a 32 bit result and then dividing it back down to a 16 bit but I had no luck.... I'll keep on trying and see what I get....

WizPic, Thanks for the hex.... It looks like I will need to use a xtal and pull mclr high....Ill give it a try asap and let you know!!! THANKS!!!!!

Hey Jaspaa, youre idea makes since but how would I figure the resistor value for the voltage divider for a factor of 6 like yore example???

how to read a amp meter

Google is your friend Check this page:

https://en.wikipedia.org/wiki/Voltage_divider

The Resistive one is the easiest and probably for your design the best. Don't choose your resistors too large or too small.

for a factor of 6 you could simply go for R2 = 10K and and R1 is 50K (R1 and R2 based on the numbering scheme from the link above)

Goodluck!

has anybody implemented Ampere meter using hall effect sensors?

has anybody implemented Ampere meter using hall effect sensors?

yes i did it with ugn 3505

chevymn1964 hows it going did you sort it out in the end, lets us know how far you got

I've moved onto the MAX7219 now and have done a volt meter using it, it was easier than i first thought

PSU set at 27.68 and my display reads 27.67

good luck

Hi Wizpic
which EPE had the voltmeter in it I must have missed it

converting adresh to bcd pic16f voltmeter

It was not in EPE sorry to say it's my own design

cheers

pic volt amper meter

Hey WizPic, Its been going really good... I have it displaying voltage within 1mv and displaying current using a max4080 with a shunt... I have also upgraded to a 24 x 2 LCD and just got done making a PCB.... Now Im working on the rest of the code for displaying min/max current readings and sound an alarm when max set current is reached.... Thanks again for all the help!!!!!!!

chevymn1964 no worries glad to be of any help it has aslo been fun in the proccess in doing it
I've started to ASM now so it give me a boot up the back side

just glad to ear you got it working teh way you wanted it to good luck and happy new to yo and every one that reads it

a picture of the actual current meter

I have designed and built my own using a PIC18F4520 runnig at 20Mhz ans it's for 4 chanels 2 x volts 0-50V and 0-10A 0.02mv +/- readings

wizpic

0.02mV in your dreams maybe...

 

[wizpic]

metering amper with pic

Melc that was a type o error it shoudl have been 1Mv i must have but to many 0's in but well spotted no body else did

+/- 1MV is good enough for me i think i can live with that but it would be nice to get +/- 0.02mv but like you day may be in your dreams

Re: ampmeter pic

Here you go the volatge mesurement dvides the input voltage and the current mesurement times the voltage which goes across the shunt resistor but you may have to paly a round with the values fisrt befor you connect it up to the pic

I done this one some time ago and can't remember what teh voltage was

the current part shuod be ok though but it gives youa basic idea

wizpic

Please what's the HEX why circuit.

Thanks

I ma in the process of laying out PCB for it has it has got to be right becasue of nosie which would affect the readings

But i have donw it in Proton Plus (basic)

wizpic

can u convert it 16f676 in plcae of PIC18F4520. i hope u do it.
pl proved it.

Yes it can be done this but this is over 2 years old , I would have to go theough the posts and down load the files to refresh my memory, give me a few days to sort it out

thanks for ur repply.if u proved it asm file & ckt.diagram also.we also try it.i have need it.

I use PDS and dont't think the asm will be any good to you
