| 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" |
| |
| include: [w1-master.yaml] |
| |
| properties: |
| gpios: |
| type: phandle-array |
| required: true |
