How to Use:
Powering the Display:
Ensure the correct operating voltage (usually 3.3V).
If using a 5V system, a level shifter may be needed for SPI signals.
Communication Interface:
The SPI interface is the most common and requires SCK, MOSI, CS, A0 (D/C), and RST.
Some modules also support parallel communication.
Library & Code Support:
If using an Arduino, libraries like U8g2 or Adafruit GFX (with modifications) can be used.
For Raspberry Pi, Python libraries such as Luma.LCD can be used.
Displaying Graphics/Text:
Use a buffer to create pixel data and send it via SPI.
The display supports bitmap graphics so images can be converted into a pixel matrix.
Initialization Sequence:
The ST7567 requires a specific initialization sequence before displaying content.
Commands include display ON/OFF, contrast adjustment, bias settings, and column/page addressing.
