Class Chip

extends Object
A GPIO chip on Linux.

Class summary

Constructors

Statics

list -> List
Lists all GPIO chips on the system.
The returned list contains paths to the GPIO chips.

Methods

close -> none
Closes the chip.
If children (like pins) are still open, the closing of the chip is delayed until all children are closed.
label -> string
The label of the GPIO chip.
name -> string
The name of the GPIO chip.
operator == other/any -> bool
Whether this object is equal to the other.
By default, identical is used for equality.
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).
pin-count -> int
The number of pins on the GPIO chip.
stringify -> string
Stringifies this object.
Inheritance
Objects that need a human-friendly string representation should overwrite this method. The default string is based on the internal class-ID.

Fields

path / string
The path to the GPIO chip.
