6. 사용 설명서
After successful physical connection, the module requires software configuration to display content. Waveshare provides example code and libraries for various platforms.
6.1 소프트웨어 설정
- 라이브러리 설치: Download and install the appropriate SSD1309 OLED display library for your chosen development environment (e.g., Adafruit SSD1306 library for Arduino, or specific Waveshare libraries for Raspberry Pi/Python).
- Configure Pins: In your code, define the GPIO pins connected to the OLED module's CS, DC, and RST pins according to your wiring.
- 화면 초기화: Use the library functions to initialize the SSD1309 driver. This typically involves setting the display resolution and communication protocol (SPI or I2C).
- 디스플레이 콘텐츠: Utilize the library's drawing functions to display text, graphics, or images on the OLED screen. Remember to call a display update function (e.g.,
display.display()) to push changes to the screen.
6.2 통신 모드 선택
The module supports both SPI and I2C. The default mode is typically SPI. If you intend to use I2C, you may need to adjust onboard jumpers or solder pads, if available, and ensure your software is configured for I2C communication (SDA for DIN, SCL for CLK, and CS/DC/RST might be tied to specific states or not used depending on the library).
