Hi guys
I am using pybricksdev to do remote control of RI robot.
I developed this from pybricksdev-demo a while back.
It was working fine but then I updated the pybrickdev library and seems like alot of changes happened and does not work anymore.
Mostly related to how we open the hub and check status now.
Looks like PybricksHub does not exist now and hub.program_running also and maybe some other hub methods.
Below is code that was working but now does not.
Can you give me some comments, examples, or other docs that might help me get upgraded to new lib?
from pybricksdev.connections import PybricksHub
from pybricksdev.ble import find_device
from asyncio import gather, sleep, run
import msvcrt
async def main():
print('main: Start')
hub = PybricksHub()
# You can search for the address like this:
address = await find_device()
await hub.connect(address)
await gather(
hub.run('robot_Blast.py', print_output=True),
forwarder(hub)
)
# Disconnect from the hub
await hub.disconnect()
print('main: Stop')
async def forwarder(hub):
print("forwarder: Start")
# Give the hubs some time to start
while not hub.program_running :
#print('forwarder: Waiting for Hub to Run')
await sleep(2)
print('forwarder: Hub Running')
# Keyboard command input loop
while hub.program_running :
# Non blocking keyboard Input
if msvcrt.kbhit():
# get char with or without echo
command = msvcrt.getch()
# clear any extra characters
while msvcrt.kbhit():
msvcrt.getch()
else:
command= ''
# Try to send to the receiving hub
if len(command) > 0:
try:
await hub.write(bytes([ord(command)]))
except:
pass
# wait some
await sleep(.1)
# Hub has stopped
print('forwarder: Hub Not Running')
#start it up
run(main())Metadata
