Piano 2.1 gpio pinout help needed..

[DRONE7]

The second oled was a simple stats RPi

Just a quick update that this was the set-up used for the second oled...

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.
