Set up your Raspberry Pi
- Raspberry Pi 2 or 3 with internet access.
- A blank Micro SD card. We recommend an 8 GB (minimum 6GB) Class 6 or Class 10 microSDHC card for installing the Raspberry Pi OS and storing the CNN model.
- Arm DS-5 installed on a host PC running Windows or Linux.
- Router and ethernet cable. This is to connect to the Raspberry Pi from a host PC using SSH.
Set up Ubuntu MATE
Set up your Pi with Ubuntu MATE and prepare it for SSH access from a separate host machine. The general steps for this are:
- Download the Ubuntu MATE 16.04.02 image file.
- Uncompress it using unxz.
- Write the image to the MicroSD card, we use dd on Linux but there are many ways.
- Insert the MicroSD card in a Raspberry Pi 3 and start it up.
Once the new system starts up, go through the configuration steps and connect to the network using a wired or wireless connection from your host machine.
Next, enable SSH by entering this on the command line:
$ sudo raspi-config
Then select Interfacing Options:
And then select SSH:
With SSH enabled, use the
ifconfig command to see the IP address of the Pi:
$ ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr b8:27:eb:22:ab:26
inet addr:192.168.0.121 Bcast:192.168.0.255 Mask:255.255.255.0
And then check that you can SSH to it from your host machine.
To save time, you can setup SSH with no password. For example:
$ ssh-copy-id 192.168.0.121
