Class ChannelInOut
extends Object
Single-wire, open-drain protocols (such as 1-Wire or DHTxx) need to both read from and write to the same pin. Each In or Out reserves the pin on its own, so two of them can't be created on the same GPIO independently. A ChannelInOut reserves the pin once, creates both channels on it, and releases everything again when close is called.
Class summary
Constructors
constructor pin/any --resolution/int --in-memory-blocks/int=1 --out-memory-blocks/int=1 --open-drain/bool=false --pull-up/bool=false
Constructs a bidirectional RMT setup on the given pin (a GPIO number).
The resolution, in-memory-blocks and out-memory-blocks are forwarded to the underlying In and Out channels. See In.constructor and Out.constructor.
If open-drain is set and pull-up is true, the pin's internal pull-up resistor is enabled.
Methods
Closes both channels, and the pin if this object created it.
Whether this object is equal to the other.
Inheritance
Classes overwrite this operator to get an equality specific to their needs. Equality operators often compare the type and field contents. For example:
class Pin:
number/int
constructor .number:
operator == other:
if other is not Pin: return false
return number == other.number
A class doesn't have to follow the above format, but it must keep the operator in sync with any
hash-code method. That is, if a class has a hash-code member, then the equality and hash-code must agree. If two instances are equal (a == b), then their hash codes must also be equal (a.hash-code == b.hash-code).
