zephyr,gpio-steppers

Vendor: Zephyr-specific binding

Note

An implementation of a driver matching this compatible is available in drivers/stepper/gpio_stepper_controller.c.

Description

GPIO Stepper Controller cluster for darlington transistor arrays or dual H-bridge

Example:
  /* Lead A is connected Lead C and Lead B is connected to Lead D*/
  stepper {
      compatible = "zephyr,gpio-steppers";
      motor: motor {
          gpios = <&gpioa 9 GPIO_ACTIVE_HIGH>,  /* Lead A1/A */
                  <&gpioc 7 GPIO_ACTIVE_HIGH>,  /* Lead B1/B */
                  <&gpiob 0 GPIO_ACTIVE_HIGH>,  /* Lead A2/C */
                  <&gpioa 7 GPIO_ACTIVE_HIGH>;  /* Lead B2/D */
      };
  };
