Step 2: Setup
1. Enable SPI
select interfacing options
2. Check to see if SPI is activated
"lsmod" -> should see something like spi_2835
3. Download Adafruit libraries
git clone https://github.com/adafruit/Adafruit_Python_MCP30...
sudo python setup.py install
4. Comment lines 13-17 in simpletest.py
5. Uncomment lines 20-22 in simpletest.py
6. Run simpletest.py and examine output

Question 2 years ago on Step 4
Hi. Congratulations for the video. Very good shared material.
I've a question on interfacing other A/D converters with Raspberry, using SPI.
I'm using MAXIM MAX191 A/D converter to interface Raspberry using SPI.
Do you see that it will also work, or it might be a complicated adaptation instead of using MCP3008?
Question 5 years ago
I understand the black and red wiring, but I don't understand the yellow/green/blue/purple going to the Raspberry pi. Why not just one cable like brown cable from the sensor?
