## What it is
Open-source firmware for BigTreeTech TFT touchscreen 3D printer controllers, written in C. It provides a touch interface and Marlin mode for controlling 3D printers from BTT TFT screens.

## Use cases
- update firmware on a BTT TFT35 touchscreen
- customize bootscreen and icons on a 3D printer TFT
- configure touch mode and baudrate for a TFT controller
- add G-code thumbnails to a TFT display
- calibrate the touchscreen on a 3D printer
- switch between touch mode and Marlin mode on a BTT screen

## When to choose
- you own a BigTreeTech TFT24/28/35/43/50/70 screen and need its firmware
- you want to customize themes, language files, or bootscreens on a BTT TFT
- you need to connect a BTT TFT to a Marlin-based 3D printer mainboard

## When to avoid
- you use a touchscreen from another manufacturer
- you need firmware for non-BTT display hardware
- you want a general-purpose embedded GUI framework

## Facets
- artifact type: application
- maturity: active
- function: embedded, gui
- domain: embedded-systems, hardware
- platform: embedded
- tags: 3d-printing, firmware, touchscreen, btt, marlin, tft
