But; how did you use both displays? Different address and pydPiper programs???
Hmmm, it was a long time ago and the Piano 2.1 project fell by the wayside due to the bug that has just been fixed by Allo/RPI.
I'm looking to resurrect the displays and finish the case and am asking myself the same questions you are....How did I do that ?
First off I checked the link and that reminded me ...
Quote:3 x i2c screens using an Ams1117 to drop the 5v from the allo hat.
Each screen has it's own unique i2c address and different software for player stats, song info, and spectrum analyser.
I've not used pydPiper as it never worked for me so the first Oled screen is this..

The second oled was a simple stats RPi (that I'm still looking for) and the third is a mystery...
However, they all ran from different scripts and didn't interfere with each other.
I will search further as time permits and post a how to if I get the displays running again.

Thanks!!! I will search too. :-)

Just a quick update that this was the set-up used for the second oled...
https://www.raspberrypi-spy.co.uk/2018/04/i2c-oled-display-module-with-raspberry-pi/
So 2 Oleds with different i2c address (usually a simple solder bridge on the back of the oled needs to be changed for one only)
Parallel connection and an Ams1117 to drop 5v to 3.3v for powering both.
One using the above stats.py and the other using Adrian's oled configuration for MoOde.

I've dispensed with the third LCD screen as it duplicated much of the information and added little.
Once I have things up and running I will post a how to ...though it is all very simple and the links should suffice for most.

A new how-to is here...

I have changed the second oled to another script...the previous mentioned has issues with a 'b' character, line spacing and fonts.(possibly because of underlying RPi changes as it worked fine a year or 2 ago)
The new script works well (Pi 3b) and shows icons and text for Load, Ram, IP, memory, and temperature.
