Using MCP3008 with Arduino

by Rahatmaini on Thu Feb 21, 2013 4:33 pm

I know how to use this chip with the Raspberry Pi thanks to Adafruit, but I am confused on how to add this to the Arduino (wiring and code) because of the pin layout in the datasheet. How do I add 8 analog pins to my Arduino Uno?

Thanks, any help is appreciated. 8)

The 3008 uses the SPI interface, so you'll want to use Arduino digital pins 10-13. Here are a couple of articles about using SPI with the Arduino:

This one talks about using the AVR's built-in SPI port: http://tronixstuff.wordpress.com/2011/0 ... e-spi-bus/

And here's one that shows examples of talking to various devices using SPI: http://tronixstuff.wordpress.com/2011/0 ... s-part-ii/
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
