In this video I show you how to access the SPI bus on GNU/Linux on a Raspberry Pi. I will write a small programm controlling a MCP23S08 8 Bit GPIO expander. We will only use some standard Linux function calls and no libraries! Enjoy!
If you need the source code, just let me know and I will upload it to my github repository.
Here is a link to the datasheet of the MCP23017 from Microchip:
