hiletgo 1.3 spi 128x64 ssh1106 oled lcd display lcd module made in china

ER-OLED013-1W is the graphic OLED display module made of 128x64 white OLED pixels,diagonal is only 1.3 inch.The controller ic SSD1306, communicates via 6800/8080 8-bit parallel and I2C/3-wire/4-wire serial interface,thanks to controller"s built-in voltage generation,only a single 3.3V power supply is needed. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast,extremely wide viewing angle and extremely operating temperature.

Need 2 of these for an "eyes" display. After mucho fiddling around, got them working (using a Teensy 3.2 as the controller), both on the same I2C bus.

Using the Adafruit SH110x library and its dependencies. Testing by modifying their SH1106_128x64_i2C_QTPY sketch. Their documentation says they need 3 pins total (clock, data, reset) but seems like they already had reset set to -1, and that hasn"t stopped it working.
