Firmware Update - Support for Local File System

We've just released an mbed Microcontroller firmware update (v14366).

This release supports the new LocalFileSystem, and makes a few other minor improvements.

To update your Firmware, open the MBED.HTM file on your mbed, click "check for firmware updates", and follow the instructions. Please tell us if you have any trouble updating.

Library Update - Build your house upon rocks, not sand

After a lot of work, we've just released a major update to the libraries (v5). Hopefully, you'll hardly notice... 

The majority of this upgrade is totally behind the scenes, getting the core robust and ready for the things we want to do with the API now and in the future. Whilst it shouldn't really be visible, please tell us if we break any of your code when you upgrade! Our next focus with the Libraries will be on the API itself, so expect some slightly more invasive improvements then. And some of the new tricks to come to light :) 

...but we couldn't do an update without giving you something new! So in addition to the new Ticker and Timeout classes, we've added file system access to the USB drive. No documentation yet, but the API page should give you a clue: 

http://mbed.co.uk/projects/libraries/api/mbed/trunk/LocalFileSystem 

We think this might find some good applications, so we're interested to hear how you use it. 

When you start a new project, you will automatically pull in the new v5 mbed Library. For existing projects, clicking on the mbed library in your file tree should provide you with an "update" button. 

As ever, please bring to our attention any problems or questions you have. 

Have Fun!

Compiler Update - More Browsers, More Robust

Some compiler updates for you for your programming pleasure... 

The compiler now has a first cut of support for Google Chrome on Windows, and Safari on Mac OS X. Whilst there are still a few rough edges, I hope you'll have fun with your new freedom! As always, please shout if you spot any problems. 

We've also implemented a basic retry mechanism in the compiler, with the aim of coping with any internet glitches. If something does go wrong on a communication, you should be given the option to "retry", and everything should spring back in to life. We've made it intentionally invasive at the moment so it is obvious a retry has occurred; please report if this happens (as with any bugs), as well as whether you were able to continue as normal after retrying. 

Have Fun!

Website Update - Handbook, Cookbook and APIs!

Whilst we've introduced most of these updates in stages over the last few weeks, I thought it'd be worth making them official! 

The basics of the Handbook are in place now at http://mbed.co.uk/handbook. This is going to be the main guide for the introductions and core mbed apis/features. Hopefully the introductions are good to get people started, and we'll be concentrating on where you go next; any suggestions for what you'd like to see welcome! 

We moved over to a "Cookbook" area which is open for anyone to add to. It has a wiki and code repository, and we'd encourage people to share projects and notes, especially the process you go through making them. We've noticed the blog-like style works well as not only does it show the answer, but also how you got there. This seems a great way to help others learn, get suggestions, etc. Go nuts! 

We've also implemented auto-documentation for our libraries (using the very elegant NaturalDocs). Still some integration improvements that haven't quite made it in yet, but getting it in there means we can start worrying about improving the documentation. And we thought it might be useful to others too, so it is also available in the Cookbook. Any code checked in to the cookbook repository gets documentation generated from it if present, so feel free to experiment yourself with your own code. 

Firmware Update - Improved Support for Serial Port

A new release of the mbed Microcontroller Firmware is available (14129). 

This release provides: 

  • Support for both Mac and Linux USB Serial Port connections by default 
  • An improved Windows Serial Port and Driver to replace the buggy Windows default serial drivers. 

Please could all beta testers update to and test this new firmware, directing any feedback about the Firmware Upgrade process and new Firmware itself back to this forum thread. To upgrade your firmware, click on the appropriate link from your mbed Microcontroller MBED.HTM file, or go directly to http://mbed.co.uk/handbook/Firmware

Instructions for using the Serial Port aspects of this new firmware can be found under "Serial Communication with a PC" in the Handbook. 

Any problems, please let us know. 

Thanks, 
Simon

Compiler Update - Support for FF3 and IE7/Vista

Just a note to say the compiler has had some updates which include a platform support upgrade! 

Revised Platform Support: 

  • Firefox 2 and 3 on Windows XP, Windows Vista, Mac OS X and Linux 
  • Internet Explorer 6 and 7 on Windows XP and Windows Vista 

So, go nuts with your new found freedom! And please tell us if you find bugs/problems/things not working how you'd expect :) 

Hope you like it.

mbed Microcontroller Beta Launch!

We decided the best way to launch something was to put it in a rocket…
