Detailed Description

Abstract base class for 1-Wire link adapters.

Any link class representing a concrete 1-Wire link adapter must inherit from this class.

The class provides some generic implementations relying only on touch*() methods. Although beeing sufficient for basic functionality, deriving classes are invited to overload those methods, especially in case the hardware provides a native implementation. Prominent examples for that:

This class is thread-safe.

Todo:
Provide assignment operator and copy constructor

Provide strongPullup method with specialized type

Create a 12 volt pulse on the 1-Wire net for programming EPROM devices.

For EPROM programming, only a single slave device should be connected to the 1-Wire bus and the cable must be short, not to exceed a few meters.

Note: One should not attempt generating a programming pulse with a non-EPROM device on the bus; this may damage the device as well as the link controller.

Note: Dependening on the implementation, time may only as accurate as the operating system permits (scheduling!).

Parameters:
inPulseTime Pulse time by predefined type.

Implemented in LOW_linkDS2480B, LOW_linkDS2490, and LOW_linkPassiveSerial.

Note: When the strong pullup is selected it will NOT appear after each byte sent, only after the last byte the pullup is done!

A default implementation relying on the touch methods is provided.

Parameters:
