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
• DataForge documentation
• Original implementation of DataForge

DataForge-control is a Kotlin-multiplatform application. Asynchronous operations are implemented with 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 library.
