SSD1322 Support about mpd_oled

[antiprism]

Hi

The file that needs to be changed to enable SPI is display.cpp. This file was renamed from display.cc, so thanks for reporting this. I will update the documentation with the new file name.

However, your display is not supported by mpd_oled so the changes would involve more than just entering the SPI configuration, and even if you are successsful then mpd_oled will only display on half the screen, unless you make further changes to the code.

@supercrab might be able to comment on this, as I believe he has looked at modifying the mpd_oled code to support your display.

Adrian.

Hi

Yes, I did manage to get this working with the same screen as you but the refresh rate was about 9 FPS on my Pi 0. It was too slow for it to be of any use because I wanted a nice and snappy equaliser.

I knocked the idea of using the head and decided to use a monochrome 2 inch monochrome I2C screen and that worked like a dream.

I can upload the code if you’re interested though

Cheers
Mase

@antiprism Thank you for your feedback!
I asumed that i also had to change other parts of the code... but isn't the way the destination? 😅
How hard this would be? But who doesn't try, won't succseed.

@supercrab Thank you for your feedback, i indeed would be happy to get the modified code!
I'm using a raspberry pi 4 /4gb for my project, that should bring more than 9fps...
So i hope i can test your modified code.

Great Comunity spirit, thank you guys!

Yes please I’ll zip it up for ya!

@antiprism Thank you for bringing me in touch with @supercrab he will send me his modified Code.
So the Incident is solved!
Thanks, guys!

Extra notes for SSD1322 support. You'll need to enable 4 wire SPI on the screen. This will require moving a 0ohm resistor or 2. This is because the DC pin is used to determine if data or command is being transmitted.
