Strange ADC behaviour

[mister_e]

EDIT: let me see...

[ruijc]

i get

voltage = 2.49
temp = 1.25

.

[mister_e]

mmm, must be too drunk and blind now..
what if you add

ansel=3
trisa=3

at the top of your code?

what if you forget the decimal point but use

lcdout $fe,2,"VOLTAGE..",dec volt," V"
lcdout $fe,$c0,"TEMP.....",dec temp," C"

instead?

[skimask]

lcdout $fe,2,"VOLTAGE..",dec volt," V"
lcdout $fe,$c0,"TEMP.....",dec temp," C"

[/QUOTE]

Shouldn't that be dec (volt/100) and dec (volt // 100) above?

[ruijc]

Thanks for the help

The code is correct like Mister-e posted because the reading values are 0.xx and with the /100 i would have just 0 !

Changed everything but i still get

porta.1 = 17
and
porta.0 = 0

changing each other i still get the same on lcd

out of curiosity, which version of PBP are you using? i've never ever used ADCIN in my program since over 5-6 years.

I may bet on some averaging... but i hate to bet on friday

[ruijc]

My version is 2.47

But i will try a 2nd pic now and see...
