Circular LED on Mega?

Hi,

Let me reuse this thread since it’s related to use of this module for another platform - this time, Intel Edison + Grove Shield.

Intel Edison uses libmraa to access its gpio port, so I read the source code of the Arduino library and wrote a mraa-version of it. Given that there’s already a mraa driver for MY9221, coding was straight-forward.

Though, the resulting behavior is not as intended. Only half of the ring gets lightened. It seems like only one of two MY9221 modules is getting the signal. Any thoughts?

I’d like to paste a link to my GitHub repo and the YouTube video executing the code, but it’s not allowed due to the anti-spam mechanism of this forum…

And now I noticed I can upload image files, interesting!
