InkyPHAT noob help

Hello!

Finally got to play with the inkyphat I bought last year, but having little luck.

Started from a fresh raspbian installation and followed the steps on https://github.com/pimoroni/inky

clean.py worked well

but then:
pi@raspberrypi : ~/inky/examples ** python name-badge.py --type phat --colour yellow Traceback (most recent call last): File "name-badge.py", line 6, in <module> from font_hanken_grotesk import HankenGroteskBold, HankenGroteskMedium ImportError: No module named font_hanken_grotesk **pi@raspberrypi** : **~/inky/examples

What am I doing wrong?

Thanks!

Yep. Same here. Pi Zero W. Latest updates as of today.

Similarly, the weather example is also missing fonts:

ModuleNotFoundError: No module named ā€˜font_fredoka_oneā€™

Iā€™m guessing i just need to work out how to install them, but it looks like the docs need updating, or the installer.

I found this line in the weather-phat.py script. Running it appeared to install the fonts needed for the weather script to work.

pip3 install geocoder requests font

EDIT
If you need the fonts installing for the first name badge example, run these:

pip3 install font_hanken_grotesk
pip3 install font_intuitive

Also, the examples further down the page donā€™t work as they are missing the .show() commands needed to actually update the screens.

Once youā€™ve finished example, update the screen with a inky_display.show() and it should then update.

e.g.

from inky.auto import auto
inky_display = auto()
inky_display.set_border(inky_display.BLACK)
inky_display.show()

Iā€™m using BLACK, not white in my example because on the black and white one I have, using white just shows an entirely white screen meaning it doesnā€™t look like itā€™s working at allā€¦

Next issue. The crontab examples in the getting started doc (Getting Started with Inky pHAT) donā€™t work. Presumably some missing info somewhere. (They just donā€™t seem to run at all!)

EDIT:

Yeah, itā€™s the addition of the virtual environment which causes the example to fail. Instead of running the python command directly, instead have it run a bash script. In that script add the command for changing to the correct environment before running the python script. Then call that (after making the script executable)

#!/bin/bash
source ~/.virtualenvs/pimoroni/bin/activate

cd /home/pi/inky/examples/
python phat/weather-phat.py

make the script executable:
chmod +x <scriptname>

add to crontab:
*/5 * * * * bash /home/pi/weatherscript.sh >> /home/pi/inkyPhat-cron.log 2>&1

(that runs it every 5mins from a home dir called ā€œpiā€ and sends output to a log file in that directory)
