Uploading from Firefox on Windows

How to compile, transfer, and run a program on your Calliope mini on Firefox for Windows.

While you’re writing and testing your programs, you’ll mostly be running them in the simulator, but once you’ve finished your program you can compile it and run it on your Calliope mini.

The basic steps are:

1. Connect your Calliope mini to your computer via USB
2. Click Download and download the .hex file
3. Click the Save As button and save the .hex file into the MINI drive

Requirements

You need the following things to transfer and run a script on your Calliope mini:

• A-Male to Micro USB cable to connect your computer to your Calliope mini. This is the same cable that is commonly used to connect a smart phone to a computer.
• A PC running Windows 7 or later, or a Mac running OS X 10.6 or later

Step 1: Connect your Calliope mini to your computer

First, connect the Calliope mini:

1. Connect the small end of the USB cable to the micro USB port on your Calliope mini.

2. Connect the other end of the USB cable to a USB port on your computer.

Your computer should recognise your Calliope mini as a new drive. On computers running Windows, MINI appears as a drive under Devices and drives. On a Mac it appears as a new drive under Devices.

Step 2: Download your program

1. Open your project on https://makecode.calliope.cc/.
2. Click Download.
3. When prompted, choose to save the compiled file onto your computer. The prompt will be different depending on which browser you are using, or whether you are using a Windows computer or a Mac.

A window may appear asking whether you want to save or open the .hex file. If it doesn’t, go click on the downloads icon at the top of the browser.

Click the folder icon and copy the file from the list of downloads to the MINI drive.

Step 3: Transfer the file to your Calliope mini

• The LED on the back of your Calliope mini flashes during the transfer (which should only take a few seconds).
• Once transferred, the code will run automatically on your Calliope mini. To rerun your program, press the reset button on the back of your Calliope mini. The reset button automatically runs the newest file on the Calliope mini.

By copying the script onto the MINI drive, you have programmed it into the flash memory on the Calliope mini, which means even after you unplug the Calliope mini, your program will still run if the Calliope mini is powered by battery.
