Hi

If you are using a 600/5 amp ct, this is intended to measure up to 600amps?
The output then usually passes through moving iron panel meters and heaters/relays to protect large a.c motors etc. ...

Yes you are right Darrel, I am using DIG 1-4 as you thought. I have now simplified program, since adval does = 1023 directly and using DIG 0-3 to send to PC. All 8 temperature readings now work...

Thanks Darrel

Now I understand, Adval by itself returns 102? and when Adval=Adval*10 it returns 1023 which is what I am using.

Thanks again.

Tom

Thanks Darrel for your formulae. Substituting 1023 for the 5 I get
1023/1023*256 *10=2560(Quanta). I was using 2600,now from Pic this gives true 10bit number(1023) at full scale that is sent to...

Hello

In the formulae ADCIN0,Adval 'read ch0 into Adval
&Adval=Adval*/Quanta (using 18f4550)
where Quanta=1251 for 0-5v input
Adval returns 0-499 ie 4.99

However for a 10 bit result I...

Thanks for your/and others invaluable help in guiding me along.

The faulty analog inputs an8, an9 and an12 when connected to a pot 0-5v would, when the applied voltage was reduced, indicate the...

I have read the data sheet and have set registers as below for 4550
TRISA = %00111111'An 0-4
TRISB = %00011111'An 8-12
TRISC = %00000000'All output
TRISD = %00000000'All output
TRISE =...

I now have the 8.15a version installed and that cured the errors.

I am now trying to get MCS easyhid to work. I have copied the 18f4550.bal plus most all files from the USB18 folder to my...
