Monochrome 2.42 128x64 OLED not working
I bought 2x Monochrome 2.42 128x64 OLEDs and i cant seem to get them to work, neither of them.
ive solderd the resistors on the back to support i2c and wired up acording the the guide for the OLED over on adafruit website. Nothing happens when i start the code(i can upload it to my feather m0 board) but it wont show anything, just pitch black.
Ive tried a I2C scanner but the scanner cant find the adress for it at all (ive tried other I2C components so the board works).
Im using 10k resistors for the voltage divide and the pull-ups on SCL and SDA(according to the guide).
Anyone got any tips?
Update: Ive tried SPI aswell and nothings happening there either.

Some of your solder joint look like they might be problematic. I would start by redoing them and making sure they look right. See https://learn.adafruit.com/adafruit-gui ... -soldering and https://learn.adafruit.com/collins-lab-soldering is you need more information/examples.

On the topside? i dont think so, all of them connect to the pad and seems to be good. But il redo them on both the displays and try again.
