I need some help to connect my NodeMCU (ESP8266) to an Adafruit SSD1306 128x32 I2C OLED display.
I want to use the default NodeMCU I2C pins, which are SDA=4(D2) and SCL=5(D1).
The Arduino library for this display has a compatibility note for the ESP8266:
"Change OLED_RESET to different pin if using default I2C pins D4/D5".
The default OLED RESET in the library example is:
#define OLED_RESET 4
So which NodeMCU pin do I connect to OLED RESET?
Can it be any digital output, or does it have to be RST?
Do I need additional pullups or capacitors to wire the OLED reset line?
And do I need to tell the SSD1306 library to use the default I2C pins D4/D5?
