Tactility “operating system” for the ESP32 microcontroller family supports built-in and external applications

Tactility is an operating system that runs on the ESP32 microcontroller series. Created by Dutch software developer, Ken Van Hoeylandt (also known as ByteWelder), Tactility is a project one year in the making inspired by the Flipper Zero and its application platform. The ESP32 operating system can run built-in apps and helper services from flash storage as well as external applications from an SD card. It leverages the Espressif ELF(Executable and Linkable Format) loader to load ELF files from external storage to the executable memory area. Tactility is built to run on any ESP32-based device with a touchscreen since drivers (display, touch, and SD card) can be implemented for any hardware. ESP32-S3 devices are “the best option” due to their performance and larger memory. The LILYGO T-Deck series is highly recommended for its onboard keyboard and sizable display. Preset configurations are available for the LILYGO T-Deck Plus, LILYGO T-Deck, M5Stack […]
