Programming the microbit using an Android phone or tablet [Copy link]

 

 

Most Android phones and tablets now have USB OTG function, so we can easily program microbit through the USB of the phone (newbit in the forum can also use this method). First, we need to prepare a USB OTG converter or a USB OTG adapter cable. In this way, microbit can be connected to the phone via USB OTG. Secondly, you need to install a new version of Chrome (Google) browser, the version must be at least greater than 65. In addition, you need to upgrade the firmware of DAPLink on microbit to enable microbit to support webusb function. The firmware version must be greater than 0246. For the method of upgrading the firmware, please refer to the previous posts in the forum, the latest DAPLink firmware download (Note: This firmware is not suitable for newbit). After the preparation, you can start programming through the browser of the mobile phone. Let's open PythonEditor first (https://micropython.top/, you can add the URL to your bookmarks so you don't have to enter it every time, or you can enter it through the online programming navigation bar in the Chinese forum). After writing the code (or using graphical programming), press the burn button and the following prompt will appear. After selecting DAPLink CMSIS-DAP, the connect button will change from gray to blue. Press the connect button and the program will start downloading. After downloading, it will run automatically. After downloading the program, if you press Open REPL, you can also enter the online REPL mode to debug the code at the bottom level. If you want to use makecode for graphical programming, you can open the makecode website (https://makecode.microbit.org/v1?webusb=1) in the chrome browser of your mobile phone. Then click the gear in the upper right corner and select device pairing in the pop-up menu. A connection prompt similar to the previous one will appear. After connecting, press the device pairing button in the lower right corner. Then select OK to allow access to the USB device. If the steps are correct, a successful pairing prompt will appear. After completing the program writing, click the download icon in the lower left corner (the one with a small arrow) to start downloading. It should be noted that because the USB OTG performance of the mobile phone is low, the download time is relatively long, which is easy to cause download timeout. Therefore, it is best to download the program once using makecode on the computer, so that there will be no mistakes when downloading with the mobile phone.

Currently, iOS does not have USB permissions.

Can webusb access HID peripherals? I'll have to study the operating mechanism when I have time.

You can take a look at the source code of DAPLink

It has nothing to do with the device side. When evaluating webusb before, I heard that HID peripherals are not supported for security reasons. https://stackoverflow.com/questi ... supported-by-webusb

I haven't tried it, I don't think it will work, Apple's system is relatively closed

I have tried it, it really doesn't work, I downloaded the Chrome browser. There is no pairing option in the settings

Use an Android tablet first, fortunately it is not expensive. If you buy a second-hand one, it only costs 200-300 yuan.
