Loop frequency regulator for asyncio.
Project description
aiorate
Loop frequency regulator for asyncio with an API similar to rospy.Rate
.
Installation
pip install aiorate
Usage
The Rate
class provides a non-blocking loop frequency limiter:
- Set the loop frequency in Hz at construction:
rate = aiorate.Rate(200.0)
- Call
await rate.sleep()
at every loop cycle
Example
import asyncio
import aiorate
async def main():
rate = aiorate.Rate(400.0) # Hz
while True:
loop_time = asyncio.get_event_loop().time()
print(f"Hello from loop at {loop_time:.3f} s")
await rate.sleep()
if __name__ == "__main__":
asyncio.run(main())
