Ultimate GPS Tracker Project - Getting Altitude from GPS NMEA Sentences - Project 11

Learn to extract altitude data from GPS NMEA sentences using a Raspberry Pi Pico W in this 50-minute tutorial. Implement a dual-core approach where one core continuously reads NMEA sentences from the Adafruit Ultimate GPS while the other core parses the data, preventing UART buffer overflow and ensuring accurate location information. Configure an SSD1306 OLED display to show GPS location data, extract and convert UTC time and date to local values, and retrieve altitude/elevation information from NMEA sentences. Add a toggle button functionality to switch between different screen displays when data exceeds the OLED's single-screen capacity, allowing you to view various GPS parameters efficiently. Master the integration of GPS hardware with microcontroller programming while building toward a complete GPS tracker project using practical embedded systems techniques.
