Hi -- I'm almost done with my LXR build but I'm unable to get the OLED display to work. All my power tests were perfect, all the LEDs light up, and I get the running pattern of LEDs at the bottom of my board when I press "Start". Everything is great except for the OLED display.
When I first turn on the LXR, I'm able to see one line of the display on the very top if I twist my encoder knob but there isn't anything below it.
I tried resoldering the obvious stuff: I reflowed the solder from the header to the board, the header to the OLED, and the bracket for the ATMEGA (I removed the chip first). Any other obvious things I can try? Any tests I can perform with my multimeter?
Thanks so much!
