⚠️ Those samples are compatible with MICROEJ SDK 6. MICROEJ SDK 5 compatible samples are available here. ⚠️

Overview

This project gathers basic examples on how to use Foundation Libraries.

By default, the samples will use the STM32F7508-DK VEE Port.

See https://github.com/search?q=org%3AMicroEJ+VEEPort&type=repositories for the list of supported boards using MICROEJ SDK.

Each sample provides a README.md that contains instructions on how to run it.

Details

Core

EDC

EDC contains the minimal standard runtime environment for embedded devices.

Available Examples:

• edc.helloworld: Prints Hello World on the standard output stream.

BON

BON focuses on devices with non-volatile and volatile memories. This library allows to fully control memory usage and start-up sequences on devices with limited memory resources.

Available Examples:

• bon.immortals: Shows how to manipulate the immortals.
• bon.immutables: Shows how to manipulate the immutables.

Communication with other hardware

HAL

HAL libraries present an abstraction of the communication with the hardware.

Available Examples:

• hal.gpio: Shows how to use GPIOs.

Audio

The Audio Foundation Library provides APIs to record and play audio.

Available Examples:

• audio.record: Shows how to record audio.
• audio.track: Shows how to play audio.

Design a user interface

MicroUI

MicroUI provides the minimal cornerstone for quick construction of advanced, portable and user-friendly applications for a wide and heterogeneous range of devices with just-what-is-needed resources.

Available Examples:

• microui.font: Shows how to create and use a font.
• microui.gradient: Shows how to draw a gradient on a display.
• microui.helloworld: Shows how to print a string on a display.
• microui.image: Shows how to create and use images.
• microui.input: Shows how to listen to the MicroUI input events.
• microui.led: Shows how to use the LEDs.
• microui.movableimage: Shows how to create and use movable images.
• microui.mvc: Shows how to create and use a MVC design pattern.
• microui.out: Shows how to redirect the standard SystemOut to the display.

Drawing

The Drawing Foundation Library extends MicroUI drawing APIs with more complex ones.

Available Examples:

• drawing.transform: Shows how to use anti-aliased shapes.
• drawing.antialiased: Shows how to apply transformations on an image.

Communication with the world

NET

NET is a lightweight Java library dedicated to networking applications. It supports stream (TCP/IP) and datagram (UDP) socket connection APIs.

Available Examples:

• net.echo: Shows a simple echo server.
• net.helloworld: Shows a simple helloworld using NET.

Bluetooth

The Bluetooth Foundation Library provides APIs to use Bluetooth in an Application.

Available Examples:

• bluetooth.central: Shows how to scan, connect and discover services.
• bluetooth.peripheral: Shows how to advertise and provide services.

Data storage

FS

FS is a library to access multiple storage devices (in and out data streams) through a simple file system API.

Available Examples:

• fs.helloworld: Creates a list of folders, adds some files and deletes them all.
