The first project i make its runs at 4MHz and now i am trying to make i run on 20MHz.

The display, keyboard and so on, works fine, but i cant get the temp on the DS18S20 or DS18B20 only the ID of the DS18B/S20 i can get.

Hard to help you with so little (and strange) information. If you can get the ID from the sensor, there is no reason why other communication shouldn't work.
