The dallas 1-wire library starts with a pin definition, like: var volatile bit _1w_dq is pin_b4 var volatile bit _1w_dq_dir is pin_b4_direction Once these...

... two ways: you can modify the Dallas routines 1. add if statements to select the correct pin 2. pass the correct pin (and probably the direction bit too) as...
hi Bert, ... Then there's no need at all to use I2C, which is meant for more (addressable) devices on 1 wire. Why not just bit-bang the correct IO-pin, like...
... Wouter, I've tried passing them to a subroutine as "bit in" but that didn't work. So how do I pass volatile parameters? Have fun, Bert www.vandam.tk...

Are you saying limit the use of volatile declarations? or is this specific to subroutines? I expected volatile variables to be the default safest choice,...
... Yes for volatile *parameters*. But I think they are not often used. The jprint lib is on place where they are used, and this happens to be a lib that has...
