Zephyr W1 GPIO node
|
||
|
|
|
||
|
|
This defines a one-wire driver through GPIO bit-banging.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
|
||
|
|
/ {
|
||
|
|
w1: w1 {
|
||
|
|
compatible = "zephyr,w1-gpio";
|
||
|
|
gpios = <&gpio0 13 (GPIO_ACTIVE_HIGH | GPIO_OPEN_DRAIN | GPIO_PULL_UP)>;
|
||
|
|
};
|
||
|
|
};
|
||
|
|
|
||
|
|
Above:
|
||
|
|
- w1 is pin 13 on gpio0. The gpio is active when the pin is high, is
|
||
|
|
configured as an open-drain, and has a pull-up resistor.
|
||
|
|
|
||
|
|
compatible: "zephyr,w1-gpio"

||
