Problem with 16F877 and DS18B20
PostPosted: Fri May 08, 2009 11:33 am     Reply with quote
Hi, guys.

I'm trying to "assemble" simple thermometer using PIC16F877 and DS12B80. I'm also using 1wire "driver" from here and flex_lcd driver from here. But the problem is that the LCD shows TEMP: -0 / COLD !

Anyone have clue ?

Thanks in advance Smile
Mitko Kostov.

Well if you would post the actual code, someone could actually help you.

#define ONE_WIRE_PIN PIN_A0

The linked driver uses pin A0. You are using pin C0. Did you change
the #define statement above to use your pin ?

Yep, I changed it, also configured the LCD with my pin configuration.

The error in Proteus :





EDIT : I was using 16F877, not 16F877A. Problem solved I guess.

Thanks.
