OpenStreetMap on an M5STACK CORE2 SoC
—
In my blog post Satellite Navigation Data on a Small Display I presented how to display data from an LC76G Satellite receiver. In this post I show how the solution was extended to show the actual position on a map. The map data is taken from OpenStreetMap and it is stored on an SD card.…
