## 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](https://github.com/flipperdevices/flipperzero-firmware/) project.
|
|
|
|
|
|
|
|
**Status: Alpha**
|
|
|
|
Tactility features a desktop with a set of applications:
|
|
|
|
 
|
|
|
|
 
|
|
|
|
|
|
|
|
Play with the built-in apps or build your own! Use one of the supported devices or set up the drivers for your own hardware platform.
|
|
|
|
Noteworthy features:
|
|
- Touch UI capabilities (via LVGL) with support for input devices such as on-device trackball or keyboard.
|
|
- An application platform that can run apps and services.
|
|
- Basic applications to boost productivity, such as a Wi-Fi connectivity app.
|
|
- Run Tactility apps on PC to speed up development.
|
|
|
|
Requirements:
|
|
- ESP32 (any?) with a touchscreen
|
|
- [esp-idf 5.2](https://docs.espressif.com/projects/esp-idf/en/v5.2/esp32/get-started/index.html) or a newer v5.2.x
|
|
|
|
## Making apps is easy!
|
|
|
|
The app manifest provides basic information like the application name.
|
|
It also describes the [app lifecycle](docs/app-lifecycle.md):
|
|
It tells Tactility which functions need to be called when the app is started/shown/etc.
|
|
|
|
UI is created with [lvgl](https://github.com/lvgl/lvgl) which has lots of [widgets](https://docs.lvgl.io/8.3/widgets/index.html)!
|
|
Creating a touch-capable UI is [easy](https://docs.lvgl.io/8.3/get-started/quick-overview.html) and doesn't require your own render loop!
|
|
|
|
```c
|
|
static void app_show(App app, lv_obj_t* parent) {
|
|
// Default toolbar with app name and close button
|
|
lv_obj_t* toolbar = tt_toolbar_create_for_app(parent, app);
|
|
lv_obj_align(toolbar, LV_ALIGN_TOP_MID, 0, 0);
|
|
|
|
// Label widget
|
|
lv_obj_t* label = lv_label_create(parent);
|
|
lv_label_set_text(label, "Hello, world!");
|
|
lv_obj_align(label, LV_ALIGN_CENTER, 0, 0);
|
|
// Widgets are auto-removed from the parent when the app is closed
|
|
}
|
|
|
|
const AppManifest hello_world_app = {
|
|
.id = "helloworld", // Used to identify and start an app
|
|
.name = "Hello World", // Shown on the desktop and app's toolbar
|
|
.icon = NULL,
|
|
.type = AppTypeUser,
|
|
.on_start = NULL,
|
|
.on_stop = NULL,
|
|
.on_show = &app_show, // A minimal setup sets the on_show() function
|
|
.on_hide = NULL
|
|
};
|
|
```
|
|
|
|
|
|
|
|
## Supported Hardware
|
|
|
|
Any ESP32 device with a touchscreen should be able to run Tactility,
|
|
because LVGL is set up in a platform-agnostic manner.
|
|
Implementing drivers can take some effort, so Tactility provides support for several devices.
|
|
|
|
Predefined configurations are available for:
|
|
|
|
| Device | Screen&Touch | SD card | Power | Other |

## Guide
|
|
|
|
### Cloning from git
|
|
|
|
Ensure you clone the repository including the submodules! For example:
|
|
|
|
```bash
|
|
git clone --recurse-submodules -j8 https://github.com/ByteWelder/Tactility.git
|
|
```
|
|
|
|
### Build environment setup
|
|
|
|
Ensure you have [esp-idf 5.2](https://docs.espressif.com/projects/esp-idf/en/v5.2/esp32/get-started/index.html) 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`.
|
|
|
|
### Development
|
|
|
|
Take a look at the [App Lifecycle](docs/app-lifecycle.md) or the [dependency diagram](docs/project-structure.puml) (this uses [PlantUML](https://plantuml.com)).
|
|
