Thanks mister_e

I guess i need glasses on this one...

lcdout $fe,2,"VOLTAGE..",dec (volt/100),",",dec2 volt,"V"
lcdout $fe,$c0,"TEMP.....",dec (temp/100),",",dec2 volt,"V"

Corrected that but still some strange behaviour...

With
porta.1 = 0.16v lcd 0.16 and porta.0=5v lcd 5

but

with porta.1 = 0.16v AND porta.0 = 0.16v lcd 0.00v on both

I'm guessing some comparator issue here...
