OWBus

OWBus is a library that handles several type of Maxim's 1-Wire probes for Arduino and ESP8266

OWBus requires the OneWire library which can be found at http://www.pjrc.com/teensy/td_libs_OneWire.html

Have a look on provided examples as well as .h files for additionnal informations.

Interfaces implementation :

OWBus (OWBus.h)

Abstracts 1-wire bus and handles

• search/discovery of probes on the network
• launch parallel temperature conversion
• ...

OWBus::Address (OWBus.h)

Abstracts 1-wire address handling

• validation
• to string conversion
• chip family identification
• ...

OWDevice (OWBus/OWDevice.h)

Generic class to handle all probles.

• 1-wire commands
• shared capabilities (parasite-powered, ...)
• ...

OWScratchpad (OWBus/OWScratchpad)

Generic scratchpad handling.

• read/write
• ...

Important Note :

Before working with a new device, please test NumberOfProbes.ino with Test bits ordering enabled. It must output "Arch Ok" otherwise open a bug report.

Features Support

• EEPROM Writing : Not implemented and will probably remain
• EEPROM Reading : To be done (or not, I'm not sure there is a need here)
• Alarms : To be done
• PIO writing : Tested ok
• PIO reading : Tested ok
