Hi Dhrone, I have installed this OLED display, but nothing happens, this is the same family off Winstar what goes wrong? I use the Raspdac but want a bigger display

Thanks Dekker

This is probably a good time to discuss how one of these support requests should be made. When you have a problem with your display, there is a lot of technical detail on your specific configuration that is needed to even begin to understand what may be wrong.

At a minimum you need to provide:

• Display make and model
• The type of SBC (e.g. Raspberry Pi 3 B+)
• The OS you are running ( e.g. Volumio 2.882, Raspberry Pi OS (May 7, 2021) )
• How you have wired your display to the SBC
• The version of pydPiper you are using
• Including a copy of your service file (as an attachment)
• Including a copy of your page file (as an attachment)
• Description of what you are trying to do
• Description of what you have tried

Being more specific is almost always more useful than less.

The good news is the display you have chosen should definitely work. When working on display issues, it is often helpful to get an example program working before attempting to get the full pydPiper system working. I've moved to using the Luma.LCD/Luma.OLED projects to drive the next version of pydPiper. I'd suggest you take a look at the Luma.OLED documentation and try to get a small sample program working with it.

See https://luma-oled.readthedocs.io/en/latest/software.html for instructions on how to install the luma.oled library and https://luma-oled.readthedocs.io/en/latest/hardware.html#parallel for an example of how to wire the display.

Here's a small sample program that should display a message if your display is working correctly.

from luma.oled.device import winstar_weh
serial = bitbang_6800(RS=7, E=8, PINS=[25,24,23,27])
device = winstar_weh(serial)

display.text = 'Winstar Display\nSuccess'

FYI, Getting luma to work correctly on many of the popular music distributions (especiall Volumio) is difficult because most lack direct support for Python3 which is a Luma.oled requirement. I would suggest using RaspberryPi OS for your testing until you get your display working correctly before attempting to get pydPiper running with the distribution you are using.
