hi guys
i think it will be easier to put this in a new topic instead of the 2 pages topic for the clock AN590.
the clock is working fine thanks to your help .
i need to add temperature display , i have a bunch of LM335 i bought a
long time ago and i like to interface it with the 16F877.
i hve a schematic that i downloaded from the internet ,dose this one work???, (i know it use LM34).
i have AN0,AN2,and AN3 available ,
do i need to use an OPAMP for the signal or it can be inerfaced directly
if any one have a schematic please post it.
iam thinking of a scale from -20C to 50C or ,and 0-120 F
thanks for your help.
