Today, I tested the wonderful IceNav firmware for the T-Deck ESP32S3 board. This development is a highly customizable GPS created from scratch for various ESP32-based boards by engineer Jordi Gauchía. Although it is still in development, it is very useful for learning and understanding different concepts, such as user interfaces built with LVGL, GPS protocols, and, of course, the ESP32. In the video, I tested the speed refresh and the heading of the map pointer. Since my device does not have a compass yet, the firmware calculates it instead. I also demonstrated the interface with PyGPSClient, as IceNav has the option to export the NMEA messages from the GPS module for use with different software like this. More details and source code:
