How run a CityHub and train motor from PyCharm on my laptop

[down0041]

1. To the makers of PyBricks - your creation is incredibly COOL and AMAZING. The very fact that I can connect to CityHub, and send a command to train motor is incredible.

2. I want to take this to the next level. I have pyCharm on my laptop. How can I create a python program there, connect to the City Hub, and run my train motor. I know I can do it from pyBricks web site, but I have a number of reasons, that I would like to do this from PyCharm.
   Please let me know, if this magic is possible and how.

Please and thank you.

There is a command line utility called Pybricksdev that can do this. You can use it with any editor (or without an editor at all), or set it up under your favorite launch shortcut in your editor.

Here are the instructions to set it up:

You can skip the steps for vscode and replace them with similar steps in your editor if you like.

Laurens! Thank you very much for your quick response. I understand your reply, but also realize, I did not state my root question very well.

My root project, is that I want to control a lego train, using a raspberry pi. (Having a dial attached to the pi, and as i dial up, increase power to the train, dial down, and reduce power to the train, etc.)

My guess is this must require:

1. python program running on CityHub, listening for commands
2. python program running on raspberry pi, sending commands.

I am hoping you can point me in the right direction. (Especially for how to connect, send and receive commands between Python running on raspberry pi, and Python code "listening" on the CityHub.) Any sample code would be greatly appreciated.
Thank you again, for your quick response.
Positive regards!

I think I have found the notes on this:

Correct?

Hi,

Maybe also a good read is at Kees Smit repo ble-pico-pybricks.
He also points to pybricks technical info ble broadcast observe

down0041, I'm very interested in any progress you make. I'd also like to build a throttle for controlling trains.
