U8G2_ST7567_128X64_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE);
void setup() {
u8g2.begin(); // Initialize the display
}
void loop() {
u8g2.clearBuffer(); // Clear the display buffer
// Draw text on the display
u8g2.setFont(u8g2_font_ncenB08_tr); // Select a font
u8g2.drawStr(0, 20, "Hello, World!"); // Draw "Hello, World!" at (0, 20)
// Draw a rectangle
u8g2.drawFrame(10, 30, 50, 20); // Draw a rectangle at (10, 30) with width 50 and height 20
u8g2.sendBuffer(); // Send the buffer to the display
delay(1000); // Wait for 1 second
}
