look at spidev in linux/Documentation/spi this is a generic spi driver The Linux kernel (4.9.x) that I'm using does not have a driver for this device You will need to add an overlay to associate the spidev with the spi bus that you will be connecting the device to, this link shows you how to do this. https://learn.adafruit.com/introduction-to-the-beaglebone-black-device-tree/device-tree-overlays Make sure you only power this device with 3.3 volts, that is what beaglebone black's pins use
