arduino-header-r3
Vendor: Generic or vendor-independent
Description
GPIO pins exposed on Arduino Uno (R3) headers.
The Arduino Uno layout provides four headers, two each along
opposite edges of the board.
Proceeding counter-clockwise:
* An 8-pin Power Supply header. No pins on this header are exposed
by this binding.
* A 6-pin Analog Input header. This has analog input signals
labeled from A0 at the top through A5 at the bottom.
* An 8-pin header (opposite Analog Input). This has digital input
signals labeled from D0 at the bottom D7 at the top;
* A 10-pin header (opposite Power Supply). This has six additional
digital input signals labelled from D8 at the bottom through D13
towards the top, skipping two pins, then finishing with D14 and
D15 at the top.
This binding provides a nexus mapping for 20 pins where parent pins 0
through 5 correspond to A0 through A5, and parent pins 6 through 21
correspond to D0 through D15, as depicted below:

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
