WebUSB
WebUSB is an emerging web standard that allows to access micro:bit from web pages. It allows for a one-click download without installing any additional app or software! It also allows to receive data from the micro:bit.
Support
- Chrome 79+ browser for Android, Chrome OS, Linux, macOS and Windows 10.
- Microsoft Edge 79+ browser for Android, Chrome OS, Linux, macOS and Windows 10.
Prepare your micro:bit
Make sure that your micro:bit is running version 0249 or above of the firmware. Upgrading is as easy as dragging a file and it takes a few seconds to get it done.
Pair your micro:bit
Here are the steps on the supported browsers:
- connect your micro:bit to your computer with the microUSB cable
- open a project
- click the triple dot icon on the Download button and click Pair device
- click on the Pair device button and select BBC micro:bit CMSIS-DAP or DAPLink CMSIS-DAP from the list.
If you don’t see any devices in the list and micro:bit has the right firmware (0249 or above), you can create a support ticket to notify the Micro:bit Foundation of the problem. Skip the rest of these steps.
Unpair your micro:bit
You will need to unpair your device from the editor to disable WebUSB.
- Click on the lock icon in the address bar
- Uncheck each BBC micro:bit CMSIS-DAP or DAPLink CMSIS-DAP device
- Reload the page
One-click Download
Once your micro:bit is paired, MakeCode will use WebUSB to transfer the code without having to drag and drop. Happy coding!
Console output
MakeCode will be able to “listen” to your micro:bit and display the console output.
