Hello Group,

I am using IAR 2.88A for development of a mega128 application.  Does 
anybody out there know of any sample code for this compiler that will 
allow me to communicate with Dallas 1-wire devices?  I know 
Codevision provides an include file and functions for this purpose, 
but I am at a loss at how to implement it with IAR

Thanks!

Ted

The protocol isn't too diffucult to implement, especially if you only 
need master mode and to work with a few specific devices.  I wrote 
some code for an ATmega to talk to a DS2404.  The main routine that 
gets or sends one bit is about 75 lines (less than half of which is 
code - the rest is whitespace and comments).
