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

The linked driver uses pin A0. You are using pin C0. Did you change

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. |
