    This project uses an M5STACK CORE2 V1.1 SoC together with a Waveshare LC76G GNSS Module to display Satellite data. On the left side of the picture you see the Waveshare LC76G GNSS Module and on the right side the CORE2 V1.1 SoC, which displays the satellite data, both connected by four wires. The display shows…

    I have bought an M5STACK CORE2 V1.1 system and now I want to start experimenting with it. Before flashing something on the system I would like to save the initial contents of the flash, so that I’m able to restore it to the system after my experiments. The result of a short internet search was…
