WiringPi supports an extension module for the MCP23s08 (8-bit) and the MCP23s17 (16-bit) SPI GPIO expansion chips.. The Raspberry Pi has one SPI bus with two enable or select signals. The MCP23s08 and MCP23s17's have 3 address select bits so in-theory you can connect up to 8 MCP23s08 and MCP23S17's on the same SPI select signal giving you a GPIO capability of an additional 128 pins per SPI. MCP3008 communicates with Raspberry Pi through SPI protocol . In raspberry Pi, SPI BUS pin pair are BCM 10 (out) and BCM 9 (in) which are connected to MCP3008 DIN pin and DOUT pin. We call it a BUS because BCM 10/BCM 9 can be shared with multiple devices. Pi accept maximum two devices for SPI bus. We call them spiChannel 0 and spiChannel 1. This can be done by installing the SPI package in the terminal window. Under the configuration menu, the SPI is enabled. The MCP3008 chip is an ADC and is connected to the Raspberry Pi. It has totally 16 pins, CH0- CH1 i.e, pin 1- pin 8 is the analog pins and rest of the pin from 9- 16 have a whole range of different pins. I looked to the procedure in the web link above, I would propose the following change in setting up spidev: 'burn' raspbian raspi-config, allow SPI and enable it at startup sudo apt-get update sudo apt-get upgrade sudo apt-get install python-pip python-dev sudo pip install spidev (so do use the spidev from repository).
