FeatherS2 with OLED 128x64 Featherwing no display

[joezilla86]

I'm trying to get an OLED Featherwing to work with a FeatherS2. I have tried connecting via the QT port and stacking headers, and neither is able to find the featherwing. I'm getting a "ValueError: Unable to find I2C display at 3c". I've also tried to connect the featherwing to a QT PY through the QT connector and am still not getting any connection. I have successfully connected other featherwings, including daisy chained through the non-working OLED wing.

I'm trying to use exactly the code from https://learn.adafruit.com/adafruit-128 ... cuitpython but nothing shows up on the screen at all.

I've also tried scanning the i2c bus with:

Code: Select all

import board

i2c = board.I2C()

while not i2c.try_lock():
    pass

i2c.scan()

Which returns

Code: Select all

[]

. I can get output from this scan if other featherwings are connected, but still not from the OLED board.

Upon closer inspection I found that the OLED is cracked. One of the corners is chipped off and there is a crack that goes along where the flex connector joins to the screen.

I don't know what to test that you haven't so Contact [email protected] with a link to this thread and they will get you a new Featherwing.
