First SPI experiment...

Hi,

for my beaglebone I bougth this RTC:

https://www.sparkfun.com/products/10160

Before I will fry anything...

Is there any howto/tutorial for using
SPI with the beaglebone?

Sure, I will find tutorials like that on the net
via G**gle, but I will not find out, whether these
tutorial / howtos are recommended and/or done by
someone else...

What tutorials / howtos are recommended for this
purpose?

Thank you very much in advance for any help!

Best regards,
mcc
