通过Python Websocket发送GameController轴位置FastAPI和evdev

如何解决通过Python Websocket发送GameController轴位置FastAPI和evdev

如何以给定的频率通过WebSocket将游戏手柄轴坐标发送到我的Electron App前端？

python脚本和Electron应用程序在同一RaspBerry Pi 4上运行。WebSocket连接（FastAPI）本身运行良好，Electron应用程序不断从python脚本接收输入。我尝试了很多事情，但无法使两个不同的循环相互配合。

    import asyncio
    from fastapi import FastAPI,WebSocket
    from evdev import InputDevice,categorize,ecodes
    
    app = FastAPI()
    gamepad = InputDevice('/dev/input/event3')
    x = 0.0
    freq = 60 #frequency in Hz

    @app.websocket("/ws")
    async def websocket_endpoint(websocket: WebSocket):
        await websocket.accept()
        while True:
            await asyncio.sleep(1/freq)
            global x
            
            # what should be here
            # I kNow the nested loop is interfering with the WebSocket loop,but what to do?
            for event in gamepad.read_loop():
                if event.type == ecodes.EV_ABS:
                    x = event.value

            await websocket.send_json(x)

非常感谢您的帮助！
