zephyr,h-bridge-stepper

Description

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

Example:
  /* Lead A is connected Lead C and Lead B is connected to Lead D*/
  h_bridge_stepper: h_bridge_stepper {
      compatible = "zephyr,h-bridge-stepper";
      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 */
  };

Properties

Node specific properties

Properties not inherited from the base binding file.

Name	Type	Details
`invert-direction`	`boolean`	Invert motor direction.
`gpios`	`phandle-array`	The gpio pin array on which the stepper inputs are to be connected This property is required.
`lut-step-gap`	`int`	Step mode selection. 1 - Half step mode 2 - Full step mode Default value: `1` Legal values: `1`, `2`
`counter`	`phandle`	Counter used for generating step-accurate pulse signals. This should be a reference to a counter node in the device tree. When this property is present, the stepper motion controller will use the counter as a timing source instead of the default work queue timing. This enables more precise step timing control. Note: The counter needs to support both set_top_value functionalities: - Setting a new top value - Attaching an ISR to the turnaround
