#include <U8g2lib.h>

// Define the display pins
#define CS_PIN 5
#define SCK_PIN 13
#define MOSI_PIN 11

// Initialize the display
U8G2_LCD_LOGO u8g2(U8G2_R0, / clock=/ SCK_PIN, / data=/ MOSI_PIN, / cs=/ CS_PIN, / reset=/ U8X8_PIN_NONE);

import machine

# Initialize the display
disp = u8g2.U8G2_LCD_LOGO(u8g2.U8G2_R0, cs=5, clock=18, mosi=23, reset=None)

# Define a function to update the display with real-time data
def update_display(telemetry_data):
  disp.clearBuffer()
  disp.setFont(u8g2.font_6x10)
  disp.setDrawColor(1)
  
  # Print real-time data on the display
  disp.drawStr(0, 10, "Temp: " + str(telemetry_data['temperature']) + "C")
  disp.drawStr(0, 20, "Humidity: " + str(telemetry_data['humidity']) + "%")
  disp.drawStr(0, 30, "Pressure: " + str(telemetry_data['pressure']) + " kPa")
  
  # Update the display
  disp.sendBuffer()

# Simulate real-time telemetry data
telemetry_data = {'temperature': 25.5, 'humidity': 60.2, 'pressure': 1013.25}

while True:
  update_display(telemetry_data)
  machine.delay(1000)  # Update the display every 1 second
```
