A small Python Asynchronous Servo library.

servo_as

A small asynchronous MicroPython servo library for controling (initially) SG90 servos with a Raspberry Pi Pico. It may work on other platforms and with other PWM controlled servos but I havn't tried.

Note: This is a very incomplete WIP project. It may run, and your welcome to browse but please don't depend on it as everything about it is subject to change!

Example Usage

import uasyncio as asyncio
from servo_as import Servo_SG90 as Servo

async def main():
    servo1 =  Servo('Servo 1',0,Servo.CENTER) 
    
    while True:
        asyncio.create_task(servo1.move_to_poistion(Servo.PLUS_NINETY))
        await asyncio.sleep(20)
        asyncio.create_task(servo1.move_to_poistion(Servo.MINUS_NINETY))
        await asyncio.sleep(20)
        

asyncio.run(main())

Assumptions

• The servo works as decribed in the datasheet.

TODO (Possibly)

1. Calibration to allow handling of 'misbehaving' servos.
