Pinning

Define your Onewire Pins with

  ONEWIRE_PORT_RANGE(PX#, PX@)

where

• PX# is a pin on PORTX
• PX@ is a pin on PORTX

every pin between and including PX# and PX@ will be a seperate Onewire bus. You can define up to eight buses on one PORT (all buses must be on the same PORT!)

If you just need a single bus, define the range like this:

  ONEWIRE_PORT_RANGE(PX#, PX#)

Example

PORTD: PIN2, PIN3, PIN4

  ONEWIRE_PORT_RANGE(PD2, PD4)
