The BLOCKS SDK
Documentation

Welcome to the BLOCKS SDK documentation.

Here you will find all the information required to start creating BLOCKS applications. A brief summary of the main sections is below.


Downloading the SDK

This section describes how to get started writing LittleFoot scripts and how to obtain the SDK source code, either via the BLOCKS JUCE module or The standalone BLOCKS SDK.


Connecting BLOCKS

Lightpad and Control Blocks communicate with a computer over USB-C or Bluetooth, and communicate with each other via magnetic connections on their sides. This section contains instructions for configuring your setup so that all the components can communicate with each other.


Discovering BLOCKS

Once you have connected your device to your computer you need to be able to discover it from your application. This section outlines the procedure for Lightpad and Control Block discovery and provides some simple example code which monitors for new connections.


Getting touch events

This section explains how to capture touch events from a compatible device and, building on the Discovering BLOCKS section, displays some example code.


Getting control button events

Lightpad and Control Blocks have control buttons, either a mode button on their side or labelled buttons on top, and this section shows you how to obtain button pressed and button released events.


Controlling LED grids

This section explains how to control the LED grid on a Lightpad.


Controlling LED strips

Control Blocks have a strip of lights running along one side and this section provides instructions for controlling the individual LEDs.


Controlling control buttons

As well as providing button pressed and button released events, control buttons also have LEDs. This section explains how to change the colour of different buttons.


Getting started with BLOCKS CODE

Learn how to use the BLOCKS CODE IDE to develop LittleFoot programs that run on BLOCKS devices.


The LittleFoot Language

Advanced SDK users can specify specialised programs to run on Lightpad Blocks. These programs must be written in the LittleFoot language, which is described in this section.


The standalone BLOCKS SDK

This section gives an overview of building and using the BLOCKS SDK as a library.


Example LittleFoot Scripts

This section provides examples of LittleFoot scripts that can be loaded onto the BLOCKS hardware.


Example BLOCKS Integrations

This section gives an example of how to integrate BLOCKS features into an existing application.


Example JUCE Applications

This section contains examples of BLOCKS applications that make use of the full potential of the JUCE library.
