Version

1.0

• first version derived from OWPJON/ARDUINO/Local/SoftwareBitBang/DeviceGeneric/DeviceGeneric.ino

* OneWire PJON Generic "OWPG" scheme:
*   Server e.g. linux machine or raspi
*      OWPJON/LINUX/Local/LocalUDP/RemoteWorker/DeviceGeneric/
*      OWPJON/LINUX/Local/ThroughSerial/RemoteWorker/DeviceGeneric/
*   Tunnel(er) similar to 1wire master (similar cause we are on a multi-master bus) e.g. AVR
*      OWPJON/ARDUINO/Local/SoftwareBitBang/Tunneler/BlinkingSwitch/
*      OWPJON/ARDUINO/Local/SoftwareBitBang/Tunneler/BlinkingSwitch_SWBB-TS/
*      OWPJON/ARDUINO/Local/ThroughSerial/SoftwareBitBangSurrogate/Surrogate/ (obsolete)
*   Devices e.g. AVR
*      OWPJON/ARDUINO/Local/SoftwareBitBang/DeviceGeneric/
*      OWPJON/ARDUINO/Local/SoftwareBitBang/OWP_DG_LCD_Sensors/ (this sketch)
*      ...
*
* Compatible with: atmega328 (Uno, Nano), atmega32u4 (Yun)
*
* Pinout:
*   1wire PJON data bus (OWPJON SWBB):
*        1WIRE DATA    -> Arduino Pin D12
*        GND black     -> Arduino GND
*
* Test on Ubuntu or Raspberry Pi Server (owpshell) confer the docu of
* following files:
*   - @ref OWPJON/LINUX/Local/LocalUDP/RemoteWorker/DeviceGeneric/DeviceGeneric.cpp
*   - @ref OWPJON/LINUX/Local/ThroughSerial/RemoteWorker/DeviceGeneric/DeviceGeneric.cpp
*
* Thanks to:
* gioblu - PJON 11.0 and support
*          @see https://www.pjon.org/
*          @see https://github.com/gioblu/PJON
