Quick Start

        await sEMG.set_sampling_rate("250 Hz")      # 配置采样率：100Hz,250Hz,500Hz (note the space)  
        await sEMG.set_wear_detection(enable=False) # 设置是否开启佩戴检测  
        await sEMG.set_filter_state(enable=True)    # 设置是否开启滤波

            print(data)  
            await asyncio.sleep(0.01)               #小延迟，防止CPU过载
