OLED display to visualize amp / streamer data through UART (RX/TX) interface

Hi there!

I recently purchase an upstream amp and found there an UART interface (RX/TX pins). Looking at this topic i found that the UART sends all needed information for a status & title display.

Then i assembled an ATTINY3216 together with a SSD1309 driven OLED display and connected this to the upstream UART interface. After severals days of coding i got this:

and for audio sources with title information:

To get a visual response when using the remote i added pop-up screens showing the current value being changed:

I’ve now created a GitHub repository with the microcontroller source code:
Feel free to use this for your own projects!

Very interesting, I might give it a go with my Pro board.
