OLED Display Software Setup:

1. OLED Display Screen Resolution, Change to your OLED display width and height.

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 32 // OLED display height, in pixels

2. OLED I2C ADDRESS

#define SCREEN_ADDRESS 0x3C

- use 0x3D if screen resolution 128x64 pixel
- use 0x3C if screen resolution 128x32 pixel

3. WiFi and Duino User

const char *ssid = "YOUR_SSID"; // Change this to your WiFi SSID
const char *password = "YOUR_SSID_PASSWORD"; // Change this to your WiFi password
const String ducoUser = "YOUR_DUINO_USERNAME"; // Change this to your Duino-Coin username

Wiring:

Change SDA and SCL accordingly with your board, this example with Wemos D1 Mini and DevKit V1

	ESP8266	ESP32	OLED
	3.3V	3.3V	VCC
	GND	GND	GND
SCL	D1 (GPIO5)	GPIO22	SCL
SDA	D2 (GPIO4)	GPIO21	SDA

Else :

Feel free to modify, optimize and/or add yours.

Misc :

Dont be confuse with OLED screen size, there are two common size :

• OLED 1.3" Display (128x64)
• OLED 0.96" Display (128x32)

**if you having difficulty on ESP8266 pin reset D4, replace it with -1
