    Reading and Writing 1-Wire (iButton) devices with PSoC 3/5/5LP

    kenny.millar

       PSoC Designer for PSoC1 has a 1-Wire component which can be used to interface with 1-Wire devices such as iButtons.

         

      PSoC Creator for PSoC 3/5/5LP Does not have a 1-Wire component.

         

      Interfacing to a 1-Wire device is so simple that maybe it's just not worth creating a whole compeont for.

         

      On my blog site I have written up what is required to detect, read from and write to a 1-Wire device. The project is based around the CY8CKIT-050 but is easily portable to just about any device or dev kit.

         

      The main article is here.

         

      The complete project is attached to this post.
