multitask

[Altlogik]

multitask is only available in this version https://beta.pybricks.com/ ?

Doesn't it work in the standard version?

[Altlogik]

please help me fix the code

[Altlogik]

UG = 0 

async def motor_a():
a = 1
while a == 1:

    enc_A = right_motor.angle()
    err = UG - enc_A
    U = err * 1 
    Motor_Left.dc(U) 
    await wait(5)

Yes, it's a brand new feature. Once it is fully tested and documented we'll move it over to the stable version.

Thanks for giving it a try! We'd love your feedback if it isn't working as expected. Here is an example:

from pybricks.hubs import PrimeHub
from pybricks.pupdevices import Motor
from pybricks.parameters import Port, Direction, Stop, Color
from pybricks.robotics import DriveBase
from pybricks.tools import wait, multitask, run_task

# Initialize devices as usual. You can do this on any hub.
hub = PrimeHub()
left_motor = Motor(Port.A, Direction.COUNTERCLOCKWISE)
right_motor = Motor(Port.B)
drive_base = DriveBase(left_motor, right_motor, wheel_diameter=56, axle_track=112)

# Task to drive in a square.
async def square():
    for side in range(4):
        # Drive forward and then turn.
        await drive_base.straight(200)
        await drive_base.turn(90)

# Task to blink.
async def blink():
    for i in range(10):
        hub.light.on(Color.RED)
        await wait(500)
        hub.light.on(Color.GREEN)
        await wait(500)

# Hello world task.
async def hello(name):
    print("Hello!")
    await wait(2000)
    print(name)

# This is the main program
async def main():
    print("Running multiple tasks at once!")
    await multitask(square(), blink(), hello("Pybricks"))
    print("You can also just run one task.")
    await hello("World!")

# Run the main program.
run_task(main())

Thanks a lot

Hello with this code i get this error: ImportError: cannot import name multitask. Can you please help me to fix it?

Hi,

Which version are you using?

I tried this program at beta.pybricks.com:

MicroPython for LEGO® Powered Up smart hubs.

v3.4.0b2 (Pybricks Beta v2.4.0-beta.4)

No problem, here.
