sparkfun,pro-micro-gpio
Vendor: SparkFun Electronics
Description
GPIO pins exposed on Sparkfun Pro Micro (and compatible devices) headers.
The Sparkfun Pro Micro layout provides two headers, along opposite
edges of the board.
Proceeding counter-clockwise:
* A 12-pin Power and Digital Input header. This has input signals
labeled from 0 at the top through 9 at the bottom.
* An 12-pin Power and Digital/Analog Input header. This
has four power pins, followed by eight inputs, with a
non-monotonically decreasing numbering.
This binding provides a nexus mapping for 18 pins, as depicted below:
1 D1/TXO RAW -
0 D0/RXI GND -
- GND RST -
- GND VCC -
2 D2 D21/A3 21
3 D3 D20/A2 20
4 D4/A6 D19/A1 19
5 D5 D18/A0 18
6 D6/A7 D15 15
7 D7 D14 14
8 D8/A8 D16 16
9 D9/A9 D10/A10 10

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.
