Support buttons

[WayneKeenan]

Support Joypad buttons.
Add buttons to the web UI

Probably using the same API as gpio zero but instead of pins use logical id. Also, use text or constant logical id's, e.g 'BTN_X' or BTN_X instead of numeric ones used for joysticks

[WayneKeenan]

Added an example here

[thymjan]

Should this example script work or is it still a draft? I can't get it working with my rock candy joypad. I connected the controller directly to the raspi and to safari. Unfortunately no success.

[WayneKeenan]

Yes, it should work for you, I tested with the same.

Do you get an error?
Please send the log messages.

Did you also update picraftzero library from GitHub?

[thymjan]

I don't have to edit the example file (button definitions), do I?
I updated from git. I don't receive error messages. By button press nothing happened. I started the script with "python3 button.py" pointed the focus to the web-page and pressed the buttons. Nothing happened in the log file.

[WayneKeenan]

You don't have to edit the example, it should work as-is, but only when the USB dongle is plugged into the Pi. I should clarify that it wont send button presses via the web client, yet. (When I tested on Mac I was running the button.py script on my Mac, not a Pi, to check the pygame backend)

I've pushed an update that has a bit more debug:

sudo pip3 uninstall picraftzero
sudo pip3 install git+https://github.com/WayneKeenan/picraftzero

Please enable debug :

sudo nano /etc/picraftzero.cfg

Add:

[logging]
debug_enabled=yes

Please re-run this on a Pi with the RockCandy dongle attached to the Pi and post the log output, thanks.

Hopefully you will see something such as:
