So, you‘ve got your SwiftIO board. Let's start with a hello world project - LED blink. Follow us step-by-step to run your first project on the SwiftIO board.

Step 1: Download and install the MadMachine IDE

At first, you need to download the MadMachine IDE. It is a simple tool to allow you to write the code and download it to your board.

The IDE is available on Windows and Mac. You could find the software package here. Select the appropriate version according to your operating system.

Note: if you're an experienced programmer, you may edit your code wherever you like and use the mm-sdk to compile your code.

Double click the downloaded file and follow the installation instructions. If you meet with any problem, you could refer to FAQ.

Step 2: Code in the IDE

OK, you're ready to code.

• Open the MadMachine IDE. Now it's empty on the right side, as you create and try more projects, it will be filled with all your projects.

• Click Create a new MadMachine project.

• Name the project. We call it "Blink". You could choose any descriptive name you like for the project. Leave the rest as they are.

• Then click Create.

Now it's time to write the code.

• Click Sources > Blink > main.swift. You always edit the code in the file main.swift. Copy and paste the following code into the file.

import SwiftIO
import SwiftIOBoard
​
let green = DigitalOut(Id.GREEN)
​
while true {
    green.write(true)
    sleep(ms: 1000)
    green.write(false)
    sleep(ms: 1000)
}

Note: there are built-in example codes in the IDE. You could click the button on the bottom left corner.

Choose GettingStarted > Blink. The code will show up in a new window.

Step 3: Prepare SD card and confirm USB connection

You could notice the message on the status bar. The board is connected yet. So you will need to connect it to your computer.

• Make sure that you have inserted an SD card into the slot.

• Connect the SwiftIO board to your computer through the Download port using a Micro-USB cable.

• Press the DOWNLOAD button beside the port. SwiftIO board will be mounted as a USB Drive on your computer.

Here is an illustrational instruction.

Note: Bad quality USB cable or some third-party USB hub may cause connection failure.

The onboard RGB LED will show the current status of the USB connection. Wait until it turns to steady green.

Step 4: Build your code and download it to the board

• Once the SD card is mounted successfully, the message on the status bar will change to "SwiftIOBoard ready".

• Click the Download button.

The IDE begins to build your project, and then download it to your board if there is no error.

After the code is downloaded, the USB drive will be removed automatically.

Well, the onboard LED starts to blink✨.
