Overview

Tactility is a front-end application platform for ESP32. It is mainly intended for touchscreen devices. It provides an application framework that is based on code from the Flipper Zero project.

Tactility provides:

• A hardware abstraction layer
• UI capabilities (via LVGL)
• An application platform that can run apps and services

Requirements:

• ESP32 (any?)
• esp-idf 5.1.2 or a newer v5.1.x
• a display (connected via SPI or I2C)

Status: Alpha

Technologies

UI is created with lvgl via esp_lvgl_port.

LCD and input drivers are based on esp_lcd and esp_lcd_touch.

Supported Hardware

Devices

Predefined configurations are available for:

• Yellow Board: 2.4" with capacitive touch (2432S024C) (see AliExpress 1, 2)
• LilyGo T-Deck (see lilygo.cc, AliExpress)
• (more will follow)

Other configurations can be supported, but they require you to set up the drivers yourself:

• Display drivers: esp-bsp and Espressif Registry.
• Touch drivers: Espressif Registry.

Guide

Until there is proper documentation, here are some pointers:

• Sample application: bootstrap and app
• Tactility: The main platform with default services and apps.
• Tactility Core: The core platform code.

Building Firmware

First we have to select the correct device:

1. If you use CLion, close it and delete the cmake-build-debug folder.
2. Run idf.py fullclean to remove any cache from previous builds (or delete build folder manually)
3. Copy the sdkconfig.board.YOUR_BOARD into sdkconfig. Use sdkconfig.defaults if you are setting up a custom board.

Now you can run idf.py flash monitor
