Hi! Can anybody help me ? I'am having some issues with a DS18B20 1 wire temperature sensor. I tryed to write a firmware for PIC16F628, starting from MAXIM application notes, but the problem is that on my serial port (with Hyperterminal) I receive "#$" characters. When i try to approach the sensor to lower or higher temperatures this values does not change . This sensor is conected at RB0. Also i use an external 11.0592 MHZ oscilator.
I'm attaching my asm code and the 1 wire header from MAXIM.
Any help, ideea would be greatfull.
Regards, Mihai.
