brickworks/examples

Examples

Each subfolder contains an example application, except the common folder, which contains common code for all examples.

In order to build an example just cd to *example*/*platofrm* and use the following platform-specific instructions.

Building for any platform requires a recent enough version of GNU Make installed.

VST3

Prerequisites

Windows (via MSYS2/Mingw-w64), macOS, and Linux OSes are supported. Building tested with GCC, probably also works with Clang.

You also need to download the VST3 SDK and place it in the same folder as the Brickworks folder, or otherwise edit common/vst3/vst3.mk and change the VST3_SDK_DIR variable to point to the correct directory.

Build

In order to build just type make. You'll find the resulting VST3 directory in build/example.vst3.

Installation

If all went fine, you can install for the current user (i.e., into the user VST3 folder) by invoking make install-user.

On macOS and Linux you can also install for all users (i.e., into the system VST3 folder) by make install.

Web

Prerequisites

You need Clang with WebAssembly target support and OpenSSL installed.

Build

In order to build just type make. You'll find the resulting output directory in build/web.

Running

The output files need to be served over HTTPS. A self-signed certificate is generated in the output directory (hence the OpenSSL requirement) to make it possible to run an HTTPS-enabled web server, e.g. http-server -S, directly on/from the output folder.

Daisy Seed

Prerequisites

Building and firmware upload was only tested on Linux. You need arm-none-eabi-gcc (for building) and dfu-util (for firmware upload) installed.

You also need to clone libDaisy, cd to it, and run make. You should either place it in the same folder as the Brickworks folder, or otherwise edit common/daisy-seed/daisy-seed.mk and change the LIBDAISY_DIR variable to point to the correct directory.

Build

In order to build just type make. You'll find the resulting output files in build.

Firmware upload

To upload the firmware:

1. branch the board to the uploading machine via USB;
2. put the board in DFU mode by pressing BOOT, then RESET, then letting go of RESET and then of BOOT;
3. type make program-dfu.

Effect examples report output parameter values and CPU usage statistics via USB serial. You can read the output by, e.g., screen /dev/ttyACM0.

Android

Prerequisites

Android examples are built without the help of Android Studio or Gradle. You'll however need to have a recent enough JDK (we need javac and keytool), as well as to download the latest stable:

• Android SDK (https://developer.android.com/studio/index.html) *;
• Android NDK (https://developer.android.com/ndk/downloads) *;
• .jars and .aars (and you'll also need to manually extract the inner .jar from each .aar, which are just ZIP files) for:
  • AndroidX Core (https://mvnrepository.com/artifact/androidx.core/core);
  • AndroidX Lifecycle Common (https://mvnrepository.com/artifact/androidx.lifecycle/lifecycle-common)
  • AndroidX VersionedParcelable (https://mvnrepository.com/artifact/androidx.versionedparcelable/versionedparcelable)
  • Kotlin Stdlib (https://mvnrepository.com/artifact/org.jetbrains.kotlin/kotlin-stdlib);
  • Koltin Coroutines Core (https://mvnrepository.com/artifact/org.jetbrains.kotlinx/kotlinx-coroutines-core);
  • Koltin Coroutines Core JVM (https://mvnrepository.com/artifact/org.jetbrains.kotlinx/kotlinx-coroutines-core-jvm);
• miniaudio.h library (http://miniaud.io/).

Then you'll probably also need to adjust paths in common/android/android.mk.

* You can install both the needed parts of the Android SDK and the NDK by downloading the so-called "command line tools" (https://developer.android.com/studio#command-line-tools-only) and using the included sdkmanager program. In such case you need to install the following packages: "platforms;android-latest", "build-tools;latest", "platform-tools", and "ndk;latest".

Build

In order to build just type make. You'll find the resulting .apk file in build.

Installation

If all went fine, you can branch your device and install using make install.

Otherwise, you can also install manually, but please remember to first uninstall the application from the device (adb install -r is not sufficient as the signature might have changed while building).

Usage and known issues

Effect examples process audio input signals, therefore they will require permission to use the capture device.

Synth examples use input MIDI. While they are coded to support hotplugging, this doesn't seem to work as expected on the devices we tested. You'll need to press "STOP" and then "START" again after plugging a new device.

iOS

Prerequisites

iOS examples are not directly built by the supplied Makefiles. These rather generate the corresponding XCode projects and required files.

For this to work you need to have the latest Xcode and XcodeGen installed, as well as a copy of the latest miniaudio.h.

Finally, you might need to adjust header search path for miniaudio in build/common/ios/project.yml.

Build

Typing make will generate the required Xcode project in build/gen.

You'll need to open it and select a development team (click on the project root in the left side pane, then choose the "Signing & Capabilities" tab, and finally pick a "Team").

At this point you can build and run as with any other iOS app.

Usage

Effect examples process audio input signals, therefore they will require permission to use the capture device.

Synth examples use input MIDI and support hotplugging.
