Hi,

What is missing from your sugested command line?

I just try the procedure for 6.5, it's almost still valid, just one modification in this part:

Code:

sudo pip install -U pip
sudo -i pip install --upgrade pip setuptools
sudo -H pip install 'luma.core==1.13.0'
sudo -H pip install --upgrade luma.oled

[TheOldPresbyope]

Convert the whole procedure to Python 3?


moOde includes python (currently 2.7.26) and python3 (currently 3.7.3) and corresponding pip and pip3. No problem there---either state the version explicitly or fiddle with the system defaults (consult the InterWeb™ on "update-alternatives" command).

Obviously, a python3 flavor of luma is available.

I downloaded raspdacmini.7z and took a quick look at the .py modules. They look pretty close to Python 3 syntax. At most they might need a minor tweak to a couple lines (in Python 3 the "for...in..." loop construct works from a list but not an interator and I didn't look to see which the current code is using).

I don't have a RaspDAC Mini so am in no position to test.

Kent

I am still struggling on

Using the test command you suggested, this is the current returned  output:-


 sudo /usr/bin/python /home/pi/oled/raspdac_oled_main.py
wlan0: error fetching interface information: Device not found
amixer: Unable to find simple control 'Digital',0

Exception - Main Module

It's weird, do u have set your dac in moOde ui and restart ?

Try this command after u do that:

Code:

amixer sset -c 0 Digital unmute

Witch pi do you own ?

PS: Can you show the content of the /boot/config.txt file ?
