Embedded Multi-Page HMI

crates.io docs.rs license rustc [CI status

An embedded page oriented HMI library supporting a few buttons as input and a constraint display as output on embedded devices.

Capabilities

  • Predefined Input Models using two, three, four or five buttons or a rotary switch.
  • Adaptable to different constraints displays: E.g.
  • Declarative page structure specification and page transition specification
    • Multiple information pages
    • Continuous page updates and page system triggered page transitions
    • Dedicated startup/ shutdown pages
    • Setting menu, submenu and edit pages

Usage

Add this to your Cargo.toml:

[dependencies]
embedded-multi-page-hmi = "0.2"

Checkout the example how to specify page structures and interaction.

Example

A documented demonstration of all capabilities is maintained as an example in this crate. The example application runs on windows, linux and OSX in a terminal using the pancurses crate.

You can run the example as follow (assuming you have rust installed):

# Get this repository from github
git clone https://github.com/almedso/embedded-multi-page-hmi.git

cd embedded-multi-page-hmi
# Build and run the example
