# Controls.kt

Controls.kt (former DataForge-control) is a data acquisition framework (work in progress). It is based on DataForge, a software framework for automated data processing.
This repository contains a prototype of API and simple implementation
of a slow control system, including a demo.

Controls.kt uses some concepts and modules of DataForge,
such as `Meta` (tree-like value structure).

To learn more about DataForge, please consult the following URLs:
* [Kotlin multiplatform implementation of DataForge](https://github.com/mipt-npm/dataforge-core)
* [DataForge documentation](http://npm.mipt.ru/dataforge/)
* [Original implementation of DataForge](https://bitbucket.org/Altavir/dataforge/src/default/)

DataForge-control is a [Kotlin-multiplatform](https://kotlinlang.org/docs/reference/multiplatform.html)
application. Asynchronous operations are implemented with
[kotlinx.coroutines](https://github.com/Kotlin/kotlinx.coroutines) library.

### Features
Among other things, you can:
- Describe devices and their properties.
- Collect data from devices and execute arbitrary actions supported by a device.
- Property values can be cached in the system and requested from devices as needed, asynchronously.
- Connect devices to event bus via bidirectional message flows.

### `demo` module

The demo includes a simple mock device with a few properties changing as `sin` and `cos` of
the current time. The device is configurable via a simple TornadoFX-based control panel.
You can run a demo by executing `application/run` Gradle task.

The graphs are displayed using [plotly.kt](https://github.com/mipt-npm/plotly.kt) library.
