OLED display on RPi 3B+ not working... settings??

[MW6WHL]

Hi All

So, I had a few issues with my MMDVM hotspot last night which have now been resolved, and I am also now setting up my RPi 3B+ to use as a mobile hotspot with the MMDVM hat for use when out and about mobile in my car. I will also eventually use this hotspot for both DMR and D-STAR.

I currently have it working fine on DMR, however the OLED display does not appear to display anything at all during any operation. Nothing is seen on startup, nor when I connect to any of the DMR Talkgroups. I have the OLED6 option selected in the Pi-Star dashboard, but though I am able to see all my Talkgroups activations on my Dashboard as normal, I am not seeing anything on the OLED display on the RPi.

Are there any other settings I should look at or is it different to using this hat on the RPi 3B+ compared to the RPi Zero W ?

Any pointers greatly appreciated. Ta.

What is the diagonal dimension of your OLED? If it is 0.96" you want OLED type 3, if it is 1.3" then type 6.

Oh dear. I feel really stupid now.
