Hey people,

I just finished uploading some videos, one of them is the Semifinals one (here):

Today I spent most of the time testing various functionalities and documenting them, some of them worked, some of them did not. Let's start with what works:

PWM and Analog inputs:

I2CSAM-BA bootloader (double tap RESET function to run bootloader mode)

I tried SPI with the Sparkfun Micro OLED module and its companion library but it gave me some compiler errors, I tried a quick-and-dirty fix for that but even after that the SPI bus seemed like plain dead, no signal on no pin (MOSI, SCLK, CS). USB is also the main pain , 'cause as seen in the videos as soon as a sketch starts the USB dies. Thanks @Atmel Corporation for implementing the double tap RESET functionality on the SAM-BA bootloader, that saved me here.

I also added the "double tap RESET" video in the details, along with a board diagram and a software diagram that briefly depict what JACK does and how it works.

Now, I'll go get some deserved sleep since the last week was quite low on sleep hours (everybody in the #Hacker Channel knows what I'm talking about!)

Cheers,

Mick
