_asyncio – Asynchronous I/O scheduler for writing concurrent code.
Asynchronous I/O scheduler for writing concurrent code.
CPython module:
asyncio
<https://docs.python.org/3.8/library/asyncio.html>
Example:
import asyncio
async def blink(led, period_ms):
while True:
led.on()
await asyncio.sleep_ms(5)
led.off()
await asyncio.sleep_ms(period_ms)
async def main(led1, led2):
asyncio.create_task(blink(led1, 700))
asyncio.create_task(blink(led2, 400))
await asyncio.sleep_ms(10_000)
# Running on a pyboard
from pyb import LED
asyncio.run(main(LED(1), LED(2)))
# Running on a generic board
from machine import Pin
asyncio.run(main(Pin(1), Pin(2)))

Module Contents
- class _asyncio.Task
This object wraps a coroutine into a running task. Tasks can be waited on using
await task
, which will wait for the task to complete and return the return value of the task.Tasks should not be created directly, rather use
create_task
to create them.
