# Uploading from Chrome for Windows
|
|
|
|
While you're writing and testing your programs, you'll mostly be [running them
|
|
in the simulator](/device/simulator), but once you've finished your program you
|
|
can **compile** it and run it on your micro:bit.
|
|
|
|
The basic steps are:
|
|
|
|
1. Connect your micro:bit to your computer via USB
|
|
2. Click **Download** and download the `.hex` file
|
|
3. Copy the `.hex` file from your computer onto the micro:bit drive
|
|
|
|
## Requirements
|
|
|
|
You need the following things to transfer and run a script on your micro:bit:
|
|
|
|
* A-Male to Micro USB cable to connect your computer to your micro:bit. 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 micro:bit to your computer
|
|
|
|
First, connect the micro:bit:
|
|
|
|
1. Connect the small end of the USB cable to the micro USB port on your micro:bit.
|
|
|
|
2. Connect the other end of the USB cable to a USB port on your computer.
|
|
|
|
Your computer should recognise your micro:bit as a new drive. On computers
|
|
running Windows, `MICROBIT` appears as a drive under Devices and drives. On a Mac
|
|
it appears as a new drive under Devices.
|
|
|
|
|
|
|
|
## Step 2 (optional): Configure Chrome to ask where to save the file
|
|
|
|
You only need to do this once.
|
|
|
|
1. Open the **Settings** for Chrome.
|
|
2. Click **Advanced** at the bottom of the page.
|
|
3. Find the **Downloads** settings.
|
|
4. Enable the setting **Ask where to save each file before downloading**.
|
|
|
|
## Step 3: Download your program
|
|
|
|
1. Open your project on @homeurl@
|
|
2. Click **Download**
|
|
3. If you did Step 2 above, Chrome will ask where to save the `.hex` file,
|
|
so save it into the `MICROBIT` drive.
|
|
Otherwise, continue with one of the options in Step 4 below.
|
|
|
|
## Step 4: Transfer the file to your micro:bit
|
|
|
|
If the file was saved onto your computer, you will need to transfer it to the micro:bit.
|
|
|
|
## Manual transfer
|
|
|
|
Your `.hex` file (created in Step 3 above) appears as a download at the bottom of the browser.
|
|
Click on the arrow next to the name of the file and then click **Show in folder**.
|
|
|
|
|
|
|
|
In File Explorer, drag and drop the `.hex` file from the download folder onto the `MICROBIT` drive.
|
|
|
|
Alternatively, right-click on the hex file, choose **Send to**, and then **MICROBIT**.
|
|
|
|
|
|
|
|
## micro:bit uploader
|
|
|
|
You can use the [micro:bit uploader](/uploader) to automatically deploy ``.hex`` files to your micro:bit!
|
|
|
|
|
|
## Step 5: After transferring the file
|
|
|
|
* The LED on the back of your micro:bit flashes during the transfer (which
|
|
should only take a few seconds).
|
|
* Once transferred, the code will run automatically on your micro:bit. To rerun
|
|
your program, press the reset button on the back of your micro:bit. The reset
|
|
button automatically runs the newest file on the micro:bit.
|
|
* By copying the script onto the `MICROBIT` drive, you have programmed it into the
|
|
flash memory on the micro:bit, which means even after you unplug the micro:bit,
|
|
your program will still run if the micro:bit is powered by battery.
