BeagleBoard.org GSoC 2013 update
In the last blog post, the students and mentors were introduced and links were given to the projects. The Minix I2C project shared a video for the last post and has progressed as far as pushing initial I2C support into the Minix mainline. A couple of the other students have now provided some videos describing their projects.
First, the Beagle-ROS project…
…and now a bit on the project to add IIO support to the Linux mainline for the BeagleBone Black ADC…
The Userspace Arduino project has also made some excellent progress, demonstrating running Arduino sketches on BeagleBone Black…
The BeagleBoard Android Boot project has also produced successful bootloading from a Nexus phone.
