SSD1306 shield does not have obvious support for devices with I2C address of 0x3D #42992

Open zerkerX opened 2 years ago

zerkerX commented 2 years ago

This is a continuation of the side-discussion from Issue #42881. The SSD1306 device supports I2C addresses of both 0x3C and 0x3D, but the current shield only supports 0x3C. This can be confusing for boards that default to 0x3D, like the Adafruit 128x64 board. Although this board can be configured for I2C address of 0x3C, this requires soldering across some jumper pads.

Some quotes from the discussion on #42881:

From jfischer-no:

Documentation for generic SSD1306 shield can be updated to mention that the default address is 0x3c.

From nandojve:

+1

I was wondering if could be valid add an specific overlay like adafruit_ssd1306_128x64.overlay which uses 0x3D address with proper documentation. This could complement @jfischer-no suggestion.

I think the original issue is pretty clear, but let me know if there are questions. I still have the Adafruit 128x64 board. The project I was thinking of using it for is a decent way down my list of ideas, but it would be nice to use Zephyr if I eventually get to it :smile:. It's a pretty populate maker display board, so I imagine there would be other users too. Unless they're all just staying in the Arduino ecosystem :shrug:.
