I'm trying some samples from the ESPxx OLED driver for SSD1306 display.

The display has worked fine in the weather station, but is not displaying at all for the few demo's I've tried:

  • SSD1306ClockDemo
  • SSD1306DrawingDemo
The I2C address was correct, but the pins were off.
In the weatherstation code, I'd been using SDA =D3, and SDC=D4
the samples were using D3 and D5 - once I switched to D3 and D4, it worked!
Very simple mistake, thought I would post this for anyone else who's starting to branch out and try some of the samples.
