Hi everyone,

For my project (Porting Arduino Libraries to PULPino) within GSoCI have
ported GPIO, interrupts and this week I have ported Timer functions.
Currently I'm working on UART libraries porting and hope to finish the
Arduino core libraries next week.

Hope everyone doing well too.

Regards
Mohr
