SPI in Embedded Linux - Quick Reference Guide
http://embeddedcraft.org/
In this video tutorial, we are showing concept of Serial Peripheral Interface (SPI), and using SPI in Linux. We are also talking about IOCTL system call in Linux. We will learn SPI interface by programming LED Interface IC MAX 7219. We will write C code.
