Maxim Integrated / OneWire

1-Wire® library for mbed. Complete 1-Wire library that supports our silicon masters along with a bit-bang master on the MAX32600MBED platform with one common interface for mbed. Slave support has also been included and more slaves will be added as time permits.

Revision:
21:00c94aeb533e
Child:
33:a4c015046956
Added class for DS2465. Added a ReadBytePower operation to OneWireMaster since this is required by the authenticators including the DS28E15. Tweaked member data of OneWireMaster. Added path to header file includes to reduce compiler setup required.
