Hardware Connection

For SPI connections, the SSD1306 screen typically requires the following pin connections:

• CS: Chip select signal used to initiate and terminate command sequences.
• DC: Data/Command control signal used to differentiate between data and commands.
• RES: Reset signal used to reset the screen.
• SCK: Clock signal that provides timing.
• MOSI: Master-to-slave data signal.

Make sure to modify these pin connections according to your specific hardware.

#define OLED_MOSI   9   //Screen D1
#define OLED_CLK   10   //Screen D0
#define OLED_DC    11
#define OLED_CS    12
#define OLED_RESET 13

Usage Method

Installing Library Files (skip this step if already installed)

1. Open the Arduino IDE.
2. Go to “Tools” > “Manage Libraries…”.
3. Search for “Adafruit ST7789” and “Adafruit GFX”, and install each library individually.

Enter the code:

Below is a simple example code that demonstrates how to initialize the screen and display text on it:
