Pulsar Python SDK

Direct USB

Use PcpOverUsb for one actuator connected directly to the computer. The actuator address must be 0.

from pulsar_sdk import PcpOverUsb, PulsarActuatorReal

usb = PcpOverUsb()  # Auto-detect when one Pulsar serial device is available.
actuator = PulsarActuatorReal(usb, address=0)

Pass a port when auto-detection is ambiguous:

usb = PcpOverUsb("/dev/ttyACM0")

usb = PcpOverUsb("COM3")

Complete short run

from time import sleep

from pulsar_sdk import ControlConfiguration, Mode, PcpOverUsb, PulsarActuatorReal

actuator = PulsarActuatorReal(PcpOverUsb(), address=0)
with actuator:
    actuator.configure(ControlConfiguration(Mode.VELOCITY))
    actuator.enable()
    actuator.set_command(1.0)
    sleep(2)
    actuator.disable()
