Example Code for Arduino UNO

#include <MicroView.h>

// Initialize the MicroView object
MicroView uView;

void setup() {
  uView.begin();  // Start the MicroView
  uView.clear(PAGE);  // Clear the screen
}

void loop() {
  uView.setFontType(0);  // Set font to type 0
  uView.setCursor(0, 0); // Set cursor to top-left
  uView.print("Hello, World!"); // Print text to the screen
  uView.display(); // Refresh the screen to show the text
  delay(1000); // Wait for a second
  uView.clear(PAGE); // Clear the screen
  delay(1000); // Wait for a second
}
