diff 1wire.h @ 41:5898fba6593c
Add temperature control.
- Split out console stuff to cons.[ch]. Set up stdio so we can use printf etc.
- Use \r\n as the line terminator consistently.
- Add OWGetTemp to get temperatures from a device.
- Load/save settings in EEPROM, defaults loaded from flash.
Nearly feature complete except you can't edit ROM IDs without a programming tool :)
(To be fixed)
Needs more testing.
