128x64 OLED FeatherWing Dim on First Use

Post by odd_water »

Hi there,

I recently purchased a Feather M4 Express and the Adafruit 128x64 OLED FeatherWing. I am using it with circuit python. I have soldered stackable headers on the feather and male headers to the feather wing and they are stacked. It is connected to my Mac with a mini usb cable.

After some trial and error I was able to get the example code on the following page to run:
https://learn.adafruit.com/adafruit-128 ... cuitpython

However, I didn't even think it was working initially since the display was extraordinarily dim. I tried plugging the board into an external usb wall power supply with the same result.

What do I do about the dimness?

The soldering on the 128x64 OLED looks great. We probably need to get you a replacement. There is no hardware brightness adjustment.

Can you just show the soldering you did (if you did it) on the Feather M4 Express?
