DS1820 & PIC16F84A subroutine

Hi to everyone.

I'm looking for a simple subroutine for reading a DS1820 with a PIC16F84A using a 2Mhz Xtal

t.i.a 8)

Not sure if this would be much help but there's a thread on Forum.Microchip called DS18B20 Temperature Readings? that contains source code for a 12F675 and DS18B20 test circuit. Please note that the 12F675 is running on the 4.0-MHz INTOSC (1.0-usec instruction cycles).

Good luck with your project. Happy Holidays. Mike

Download Maxim Application Note 2420 from Dallas/Maxim website.

It shows all the required ASM routines (they use a pic16f628 with a 4Mhz clock but you should be able to adapt them for the 16f84 and 2Mhz fairly easily).

Thank you guys. It's working now
