Not able to run lego passenger train due to Bleak error #22

Open JosephArnold opened 4 years ago

JosephArnold commented 4 years ago

I tried running my lego passenger train using bricknil on my Windows 10 machine. I followed the following steps. pip install bircknil

I ran a simple program to control the train and this is the error I got.

My program had the following lines

`from curio import sleep from bricknil import attach, start from bricknil.hub import PoweredUpHub from bricknil.sensor import TrainMotor from bricknil.process import Process import logging

@attach(TrainMotor, name='motor') class Train(PoweredUpHub):

async def run(self):
    self.message_info("Running")
    for i in range(2):
        self.message_info('Increasing speed')
        await self.motor.ramp_speed(80,5000)
        await sleep(15)
        self.message_info('Coming to a stop')
        await self.motor.ramp_speed(20,1000)
        await sleep(2)

async def system(): train = Train('My train')

if name == 'main': logging.basicConfig(level=logging.INFO) start(system) `

On running the program, I got the following error.
