Hi!

I used Dallas DS1620, PIC16f84 and a Hitachi HD44780 based 2x16 LCD displ=
ay
to measure room temperature and display it on LCD. It's 1/2=B0C accurate =
and
for now it only deals with temperatures, higher than 0=B0C. It's somethin=
g I
work on currently, so in future I plan to control LCD in 4 bit mode, I'll
add routine that deals with negative values and improve accuracy to 1/10=B0=
C.
Regards,Samo

Subject: [PIC]: Easy ambient temp measurement


Hi all,

The project that I am currently working on requires me to measure the
ambient temperature.

I fancy using one of the Dallas IC's (or similar IC) to do this. I was ju=
st
wondering if anyone has used anything like this (think it was mentioned i=
n a
recent thread). Does anyone know which is the easiest to interface as I a=
m
up against a tight deadline. If anyone has some code to use such a device
that would be a great help.

Thanks

Garahm
