Commands missing from documentation? #55

Closed Tigwin closed 1 year ago

Tigwin commented 1 year ago

JFYI, I tried running this on a fresh install of raspbian and had a bunch of errors of missing modules. I fixed them with:

pip install pytz pip install caldav pip install astral pip install google_auth_oauthlib pip install google-api-python-client pip install icalevnt pip install msal

Hi they shouldn't be missing, I've got them in the requirements.txt. I assume as long as you ran the sudo pip3 install -r requirements.txt line those should have been installed.

hey - thanks. I might have missed the command, though I thought I ran it.

Everything works great, I think this is the most comprehensive waveshare tutorial/code that I've seen so far. Only thing I need now is to find a way to display stocks on the side instead of calendar :)

FWIW there's a section about adding custom data, although looking at the README the formatting is messed up, oops. I'll fix it later.

It says:

add your own custom data to the screen. For example this could be API calls, data from Home Assistant, PiHole stats, or something external.

Rename screen-custom-get.py.sample to screen-custom-get.py. Do your custom code, and set the value of custom_value_1 to the value you want to display. Run ./run.sh and it'll appear on screen.

Next, modify screen-custom.svg and change the various x, y, font size values to adjust its appearance and position. You can add more values by adding more SVG elements for custom_value_2, custom_value_3, and so on, and set its value in the output_dict in screen-custom.get.py.

Anyway it should be possible, I've never tried anything comprehensive there. What you could do do is populate the dictionary from your API calls in screen-custom-get.py, and position its x/y, in screen-custom.svg. Maybe add some CSS to the calendar sections, in the main layout SVG, to make it invisible?
