XXX: Load Hivetool on the Pi

This page is old and should probably be deleted. Please click on the Discussion tab for changes.

For a system overview and software flow diagrams see the Software page. It is easier to download an image that already has Hivetool installed. The steps below will load hivetool on a Debian based system. Some of this software (hx711, dht22, 2591) uses hardware specific to the Pi. Also see Create SD Image Version 0.71 for notes on creating an image for the Pi.

Get the latest operating system image

Raspbian Wheezy is currently used, although others should work.

The latest image available from http://www.raspberrypi.org/downloads is: 2014-09-09-wheezy-raspbian.zip

1. Download the zipped image (approximately 900 MB)
2. Calculate the SHA-1 checksum. On Linux, the command line is:

   sha1sum 2014-09-09-wheezy-raspbian.zip

   This will print out a long hex number which should match the "SHA-1 Checksum" line for the SD image you have downloaded

3. Extract (unzip) the image. On Linux the command line is:

   unzip 2014-09-09-wheezy-raspbian.zip

When unzipped, 2014-09-09-wheezy-raspbian.img is about 3.3 GB.

Copy the image to the SD card

Make SD card on Unix/Linux system

Detailed instructions: http://elinux.org/RPi_Easy_SD_Card_Setup#Flashing_the_SD_Card_using_Linux_.28including_on_a_Pi.21.29

1. Determine the device for the card reader (/dev/mmcblk0 on my laptop).
2. Copy the image to the SD card:

   dd bs=4M if=2014-09-09-wheezy-raspbian.img of=/dev/mmcblk0

Make SD card on Windows system

raspberrypi.org recommends using: http://sourceforge.net/projects/win32diskimager/ But be careful. REMOVE any other USB memory devices from your computer. Detailed instructions: http://elinux.org/RPi_Easy_SD_Card_Setup#Flashing_the_SD_Card_using_Windows

Boot Pi, expand file system, set locale, timezone and host name

Access to the Pi's console is needed. A USB keyboard and either a HDMI or composite video monitor can be used. I prefer to use a USB to TTL Serial conversion cable that is connected to pins 4,6,8,10 on P1. The other end is plugged into a USB port on my laptop. A terminal emulator is required(on Linux I use MiniCom, on Microsoft Windows hyperterm or PuTTY can be used.) The advantage of connecting this way is the command lines can be cut from the instructions below and pasted into the terminal.

1. Boot Pi and login
2. Expand file system, set locale, timezone and hostname using the Raspberry Pi Software Configuration Tool (raspi-config)

   sudo raspi-config

3. Reboot the Pi

Note 1: down arrow to: [*] en_GB.UTF-8 UTF-8 Press the space bar to uncheck. Down arrow to: [ ] en_US.UTF-8 UTF-8 and press the space bar to check. Press Tab to move to [OK] and press Enter. Set the default locale for the system environment to en_US.UTF-8 UTF-8 and select OK. This will take a few minutes.

Note 2: Set the hostname to what you want to call your hive.

Note 3: When you exit the Raspberry Pi Software Configuration Tool after expanding the file system, it will ask you if you want to reboot. You will need to reboot for the expanded file system to take effect, so reboot now.

Install required packages

Note the obvious:
1. The Pi must be connected to the internet to update or add packages!
2. Always update before trying to add packages

sudo apt-get -y update

Note: Running apt-get update does not fix the shellshock bash vulnerability. 
      Test by running: env x='() { :;}; echo vulnerable' bash -c "echo this is a test"
      If it prints "vulnerable", you should also run:
      sudo apt-get -y dist-upgrade

1. Get gawk, bc for shell scripts, apache for webserver, libusb to read TEMPerHUMs, graphics library for GD::Graph, expat library for XML::Simple, mySQL if desired.

   Either for SQLite (suggested)

   sudo apt-get -y install gawk bc apache2 libusb-dev libgd-graph-perl libexpat1-dev sqlite3

   Or for MySQL (deprecated)

   sudo apt-get -y install gawk bc apache2 libusb-dev libgd-graph-perl libexpat1-dev mysql-server

   Note: You will be prompted for the MySQL root password. Do not forget it. You will need it later.

2. Now get Graphics, XML and Database Interface for perl.

   sudo cpan GD::Text GD::Graph Date::Format XML::Simple DBI DBD::SQLite

Install Hivetool programs

1. Make two directories: /home/hivetool and /home/downloads.

   sudo mkdir /home/hivetool /home/downloads

2. Get the perl code, the shtml files and the patched pm and copy it to the perl module directory

   cd /home/downloads

   sudo git clone https://github.com/hivetools/perl

   sudo cp perl/axestype.pm /usr/local/share/perl/5.14.2/GD/Graph/axestype.pm

   sudo cp perl/*.pl perl/*.shtml /var/www/

3. Get the hivetool bash scripts and copy them to their proper directory

   sudo git clone https://github.com/hivetools/bash

   sudo cp bash/*.sh /home/hivetool/

4. get the crontab file

   sudo git clone https://github.com/hivetools/cron

Done installing hivetool files

Set the Ethernet parameters and DNS servers

If you do not intend to open a hole in the firewall to allow public access to the web server, skip this step and let the Pi obtain an IP from the DHCP server in the router. Even if you configure port forwarding in the router (for WAN access to the web server, or to secure shell (SSH) in) a static IP may not be required.

This section has changed. Please click on the Discussion tab at the top of this page for changes.

To set a static IP if needed for port forwarding through the firewall.

1. set static ip for port forwarding

   sudo vi /etc/network/interfaces:

   iface eth0 inet dhcp

   iface eth0 inet static

   address 192.168.254.31

   netmask 255.255.255.0

   gateway 192.168.254.254

2. Set the dns Servers

   /etc/network/interfaces

   /etc/dhcp/dhclient.conf

Configure MySQL

Note: MySQL is still supported but SQLite is recommend instead of MySQL. Running an SQL database locally on the Pi is optional. However, it is necessary to run the latest graphing software. This configuration was taken from ducky-pond's how to install and optimize mysql on raspberry pi

1. sudo mv /etc/mysql/my.cnf /etc/mysql/my.cnf.bak

   sudo cp /usr/share/doc/mysql-server-5.5/examples/my-small.cnf /etc/mysql/my.cnf

Configure SQLite

Running an SQL database locally on the Pi is optional. However, it is necessary to run the latest graphing software. SQLite is used instead of MySQL to lower memory and CPU usage. Run the .sql scripts to set up the database:

sqlite3 hivetool_raw.db
sqlite> .read create_hivetool_sqlite.sql
sqlite> .quit

Configure apache

1. Set up apache to listen on port 8080 if using port forwarding:

   sudo vi /etc/apache2/ports.conf

   add Listen 8080

2. Add .pl to AddHandler cgi-script

   sudo vi /etc/apache2/mods-enabled/mime.conf

   uncomment #AddHandler cgi-script .cgi (around line 219) and add .pl so it looks like:

   AddHandler cgi-script .cgi .pl

3. add Includes and +ExecCGI to Options:

   sudo vi /etc/apache2/sites-enabled/000-default

   In stanza <Directory /var/www/>

   change

   Options Indexes FollowSymLinks MultiViews

   to

   Options Indexes FollowSymLinks MultiViews Includes +ExecCGI

4. Add index.shtml to DirectoryIndex:

   sudo vi /etc/apache2/mods-enabled/dir.conf

   Change

   DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm

   to

   DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm index.shtml

5. Copy the include.load module to enable it

   sudo cp /etc/apache2/mods-available/include.load /etc/apache2/mods-enabled/

6. Restart Apache

sudo apachectl restart   or      sudo/etc/rc4.d/S02apache2 restart

Install the HX711 scale software

Note: This software was written to talk to the HX711 board via two General Purpose Input Output (GPIO) pins found on header H5 on the A and B models of the Pi. Neither H5 nor the GPIO signals associated with it are available on the A+ and B+ models. Also, H5 was not populated. To use it, pins must be soldered to the Pi. We are trying to standardize on GPIO pins found on all models (see GPIO Pinout for a chart) and recommend using GPIO pins 23 and 24 (Step 3.1 below).

1. Download the software from gitHub

   cd /home/downloads

   sudo git clone https://github.com/ggurov/hx711

2. Edit hx711.c with nano or vi and change the GPIO pins from 30 and 31

   cd hx711

   nano hx711.c ( or vi hx711.c )

3. Select the proper GPIO pins on lines 13 and 14 (select either step 1 or 2 below).
   1. If using H1 (the header on the Model A or B) or J8 (the header on the A+ and B+), pick two unused GPIO pins but we recommend using 23 and 24:

      #define CLOCK_PIN 24

      #define DATA_PIN 23

   2. If using H5 on the Model A or B (deprecated, not recommended and not available on the model A+ or B+), change to 28 and 30. This way they are all on one side of P5:

      #define CLOCK_PIN 30

      #define DATA_PIN 28

4. Compile:

   gcc -o hx711 hx711.c gb_common.o

5. Copy hx711 command to /usr/local/bin:

   sudo cp hx711 /usr/local/bin

Install the TEMPerHUM software

tempered can be installed with just the binaries (quicker) or from source (you have the source code to fix bugs)

Install binaries

1. get the binaries and libraries

   cd /home/downloads

   sudo git clone https://github.com/hivetools/tempered_pi

2. copy the files to their directories

   cd tempered_pi

   sudo cp hid-query tempered /usr/local/bin/

   sudo cp libtempered-util.so libtempered-util.so.0 libtempered.so libtempered.so.0 /usr/lib/arm-linux-gnueabihf/

   sudo cp libhidapi-hidraw.so.0 /usr/local/lib/

   sudo cp tempered-util.h tempered.h /usr/local/include/

3. run ldconfig (or reboot) to load the new library

   sudo ldconfig

4. Test by plugging in a TEMPerHUM and running:

   sudo tempered

5. It should return something like:

   /dev/hidraw1 0: temperature 20.69 °C, relative humidity 46.0%, dew point 8.6 °C

Install from source

Edit the cron table

The scripts that read the sensors, log the data, and send it off site (if enabled) are run periodically by the scheduler, cron. Cron setup can be done from the command line with crontab. For cron setup and examples, see Sample contab entries

sudo crontab -e

Set or change hostname

If the hostname was not set above using raspi-config, set the hostname:

1. Set the local host name

   sudo vi /etc/hostname

2. and edit the local host name here, too:

   sudo vi /etc/hosts
