Modifying Source Code & Deploying to Pi

While waiting for my Automation Hat to arrive, I've been testing Hydrosys on my Pi with the sensors I have on hand. So far, so good with your software.

I'm a programmer as well, but I'm not very familiar with the Pi. I was wondering what the process would be for modifying the source code, then deploying the modifications to the Pi.

What I figure is that I'd create a fork of your project and fool around with that.

But what is the best way to install my own fork onto the Pi without re-imaging the Pi and wiping out all the data that's already on it? I don't want to create conflicts with your existing software, but I'd like to test out some new data visualizations and whatnot.

Will not reload the code. First you have to kill the current python running in background by using sudo killall python3. Then to start the program again you can type in the autonom folder: sudo python3 bentornado.py

Thanks. I'll give that a try.

Hi, the python code in the PI is in the folder home/pi/env/autonom you can directly modify the code there

If I modify the .py files there, will that be the live code? I notice that there are .pyc files in that directory as well. Will simply deleting the corresponding .pyc work to make the new code immediately used? (Basically, I'm not sure when Python reloads the code.)
