In this video I will show you how we can use one core on the Raspberry Pi Pico W to continuously read the NMEA sentences from the Adafruit Ultimate GPS, and use the other core to parse them. We configure the program to ensure the UART buffer does not overflow, creating corrupt and stale location data. Then we have added a small SSD1306 OLED display to the project that shows location data from the GPS. Enjoy! We are actually pursuing building a GPS Tracker, and this is the gear we will be using in this class: Raspberry Pi Pico W: Adafruit Ultimate GPS: External Antenna (OPTIONAL): Button Battery For Quicker Fix: Breadvolt Power Supply (OPTIONAL): Charging Cable (If You Don’t Have): Soldering Iron: Solder Practice Components: Extra Solder: Safety Glasses: #oled - - *LEGAL DISCLAIMER:* The code, hardware setups, circuit diagrams, mathematical calculations, and technical methods provided in this video are strictly for educational and demonstration purposes.
