MM SDK

MM SDK

The mm-sdk contains everything you need to build a MadMachine project, either a library or an executable.

A MadMachine project is structured the same as a Swift package.

Download the latest release depending on your OS on the Releases page.

What is inside the SDK

  1. Boards
    • Board abstraction libraries based on Zephyr
  2. mm
    • Python script to help to build the project
  3. usr (This directory is only contained in the release package, not in the git repo)
    • Clang, Swift compiler, SwiftPM tools, etc.
    • Standard library and arch related libraries
    • Compiled Python build tool

Usage (macOS and Linux)

Install required dependencies:

Download the mm-sdk

Download and unzip the sdk to the directory ~

~/mm-sdk/usr/mm/mm -h command for quick help.

~/mm-sdk/usr/mm/mm init -h command for quick help about initializing a project.

~/mm-sdk/usr/mm build -h command for quick help about building a project.

Initialize an executable DemoProgram in ~/Documents

cd ~/Documents
mkdir DemoProgram
cd DemoProgram
~/mm-sdk/usr/mm/mm init -b SwiftIOFeather

or

python3 ~/mm-sdk/mm/src/mm.py init -b SwiftIOFeather

The Package.swift should look like below

// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.
import PackageDescription
let package = Package(
name: "DemoProgram",
dependencies: [
// Dependencies declare other packages that this package depends on.
.package(url: "https://github.com/madmachineio/SwiftIO.git", .upToNextMajor(from: "0.0.1")),
.package(url: "https://github.com/madmachineio/MadBoards.git", .upToNextMajor(from: "0.0.1")),
.package(url: "https://github.com/madmachineio/MadDrivers.git", .upToNextMajor(from: "0.0.1")),
],
targets: [
// Targets are the basic building blocks of a package. A target can define a module or a test suite.
// Targets can depend on other targets in this package, and on products in packages this package depends on.
.target(
name: "DemoProgram",
dependencies: [
"SwiftIO",
"MadBoards",
// use specific library would speed up the compile procedure
.product(name: "MadDrivers", package: "MadDrivers")
]),
.testTarget(
name: "DemoProgramTests",
dependencies: ["DemoProgram"]),
]
)

Build an executable

cd ~/Documents/DemoProgram
~/mm-sdk/usr/mm/mm build

or

python3 ~/mm-sdk/mm/src/mm.py build

Download an executable to the board

After building your project successfully, there would be .build/release/feather.bin in your project directory. Note that the .build directory is hidden by default.

Follow those steps to download the executable:

  1. Insert an SD card into the board and connect it to your computer through USB cable
  2. Press the Download button and wait until the onboard RGB LED turns to static green)
  3. A USB disk drive should be mounted on your computer
  4. Copy the feather.bin to the SD card root directory
  5. Eject the USB drive and the program would run automatically

Download an executable to the board using command (Only on macOS now)

After mounting the SD card:

cd ~/Documents/DemoProgram
~/mm-sdk/usr/mm/mm download

or

python3 ~/mm-sdk/mm/src/mm.py download

This command will find the corresponding bin file, copy it to the SD card and eject the SD card automatically.
