nextion-flash

A software for flashing tft files to nextion displays via a Serial connection.

The idea for this software was born from the desire to learn Rust better, and several broken SD cards trying to flash the nextion display.

Use with caution! Although it hasn't happened yet after 100+ flashes, it might brick your device!
