Hello everyone.
I am looking for the circuit of LM35 temperature sensor interfacing to a microcontroller, by the way I am using PIC16F877A. And also, a sample code in assembly where show the convertion of analog signal into digital.
Thank you.
 

i interfaced the LM35 with Pic 16F877 but i did programing in C langauge is it helpful to u
 

Thank you for your reply.

If you don't mind may I have a copy, what I mean the schematic diagram and the program code even though it is written in C. Because I thought that is really help me a lot.

Thank you.
Best regards.
