The Windows Driver seem to work very well even with custom Windows 10 IoT Core builds;
I do however notice that at an SPI driver is not present/missing?

Is there any plans to develop an SPI device driver that emulates SPI via GPIO bit banging ?

Hi Sir,
JaguarBoard has SPI interface integrated, but we did not lead the pins out. Maybe we will make it happen in next version.

We do not have the plan to develop a SIP device driver that emulates SPI via GPIO yet.
