No big announcement from the LEGO side, but it seems that the source code for the 1.29 firmware is now available at the LEGO website.  You can download it right here: [LINK].  As per usual, the naming standard of LEGO’s downloadable files will make identifying the file super easy.

In order to compile this, you will need a copy of IAR’s Embedded Workbench for LEGO MINDSTORMS NXT.  It’s free and you can download it here: [LINK].

Now that these sources have been released, I’m sure it won’t be long before John Hansen will be able to release the sources for his enhanced firmware.
