Raspberry Pi configuration

Power with USB to TTL serial cable connection

• Pin 2: 5V(red)
• Pin 6: Gnd (Black)
• Pin 8 : Tx (White)
• Pin 10: Rx (Green)

Change keyboard layout

Install required packages:

sudo apt-get install console-data keyboard-configuration

Reconfigure and choose from the list:

dpkg-reconfigure console-data
dpkg-reconfigure keyboard-configuration
service keyboard-setup restart

Create user

useradd username -m -p password
usermod -aG dialout,sudo username

Static ip

Edit /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
   address X.X.X.X
   netmask 255.255.255.0
   gateway X.X.X.1

Change computer name

Edit /etc/hosts:

127.0.0.1     localhost
127.0.1.1     COMPUTER_NAME

Edit /etc/hostname:

COMPUTER_NAME

Add 1-Wire support

Start by adding the following line to /boot/config.txt

You can edit that file with nano by running sudo nano /boot/config.txt and then scrolling to the bottom and typing it there

dtoverlay=w1-gpio

Add the required modules at the bottom of /etc/modules

w1-gpio
w1-therm

reboot with sudo reboot

Test

cd /sys/bus/w1/devices
ls
cd 28-xxxx (change this to match what serial number pops up)
cat w1_slave

Script to add Arduino vendor info

This is useful to upload Arduino code from the Pi to the Arduino board

Create a file get_arduino_id.sh, and copy this content:

echo "Getting usb ids for Arduino…"
# Search for the keyword Arduino and print the sixth column of that line
vendorInfo=$(lsusb | awk '/Arduino/ {print $6}')
idVendor=${vendorInfo:0:4}
idProduct=${vendorInfo:5:4}
symlink="USBT001"
echo "Writting vendor info..."
echo "SUBSYSTE  M=='tty', ATTRS{idVendor}==$idVendor, ATTRS{idProduct}==$idProduct, SYMLINK=$symlink" > /etc/udev/rules.d/99-usb_serial.rules

Make it executable:

chmod +x get_arduino_id.sh

Connect your arduino board and launch the script:

sh get_arduino_id.sh
