RC.DISPLAY

The display module writes text to the dot matrix on the back of the car and opens image windows on the Jetson desktop.

METHODS

rc.display.show_text(text: str, scroll_speed: float = 2.0)returns None

Shows text on the dot matrix panel on the back of the car. Text wider than the panel scrolls automatically; the firmware ignores scroll_speed.

rc.display.clear()returns None

Returns the dot matrix to its idle frame. To blank the panel instead, call show_text(" ").

rc.display.show_color_image(image)returns None

Opens a window on the Jetson desktop showing the given color image. Needs a display: use it at the car or over Remote desktop, not plain SSH.

rc.display.show_lidar(samples: NDArray, radius: int = 128, max_range: int = 1000, highlighted_samples: list[tuple[float, float]] = [])returns None

Opens a window on the Jetson desktop plotting a LiDAR scan top-down, with the car at the centre. Needs a display, the same as show_color_image.

EXAMPLE USAGE

python
import racecar_core

rc = racecar_core.create_racecar()

def start():
    rc.display.show_text("NEO")

def update():
    pass

rc.set_start_update(start, update)
rc.go()
