I connected the OLED and DS3231 RTC pins SDA and SLC pins together and since then the screen stays blank!
Not even the examples work only the feather Wing example makes it work and nothing else .
And It gets stuck on checking on IO test
The only Feather Wings I know about are on birds, posting links to technical information on all hardware devices saves all of us a lot of time.
Nope the SDA and SCL pins do not get connected together. Solution: I would say check that purple wire, the red stripe is probably the problem. That is about the best I can give you as I do not have a clue as to how it is wired or what your code looks like. OLED tells me it is a specific type of display with maybe a million variations which one do you have. Your " ??? " Arduino might not work. Posting an annotated schematic would help a lot as I do not read frizzys.
Please read the Forum guidelines before uploading your schematic and code.
The SDA and SLC pins together and then on A4 and A5 pins of Arduino was one of my previous attempts to make my project work I've mentioned it cause the i2C address might got messed up.
Now I'm connecting the i2c on a separate breadboard as normal 5V and GND pins and SDA and SLC pins on A4 and A5 pins of the Arduino.
I'm trying to see if the display works with the example Adafruit Sketches:
The normal i2c 128x64 example won't work the display still stays blank .
The only example Sketch that works is one called FeatherWing and mostly test remote access? I couldn't figure it out since it goes stuck on IP I/O testing
Run the I2C scan program, if it does not return the correct addresses for the devices you have connected. If that does not work you have either wired it wrong or have a bad part.
