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.
Status: Alpha
Tactility features:
- A hardware abstraction layer
- UI capabilities (via LVGL)
- An application platform that can run apps and services
- PC app support to speed up development for ESP32 apps
Requirements:
- ESP32 (any?) with a display that has touch capability
- esp-idf 5.1.2 or a newer v5.1.x
Technologies
UI is created with lvgl. Any LVGL-capable device is supported.
In general, esp_lvgl_port is the preferred solution if it supports your hardware: Those LCD and input drivers are based on esp_lcd and esp_lcd_touch. They are generally available via the Espressif Registry: here and here
Supported Hardware
Devices
Predefined configurations are available for:
- LilyGo T-Deck (see lilygo.cc, AliExpress)
- Waveshare S3 Touch LCD 4.3 (docs)
- Yellow Board 2432S024C: a 2.4" display with capacitive touch (see AliExpress 1, 2)
- (more will follow)
Other configurations can be supported, but they require you to set up the drivers yourself.
Guide
Build environment setup
Ensure you have esp-idf 5.1.2 installed, then select the correct device:
Copy the sdkconfig.board.YOUR_BOARD into sdkconfig. Use sdkconfig.defaults if you are setting up a custom board.
Building firmware
You can run idf.py flash monitor, but there are some helpers available too:
./build.sh - build the ESP-IDF or the PC version of Tactility (*)
./build.sh -p /dev/ttyACM0 - optional: you can pass on extra parameters for esp-idf builds
./run.sh - Does flash and monitor for ESP-IDF and simply builds and starts it for PC
The build scripts will detect if ESP-IDF is available. They will adapter if you ran ${IDF_PATH}/export.sh.
