The Pi 2 has some difference in the config settings.

Thanks to @ajfisher

Add support for @geekscape's project

Scope and functionality?

These were the mods I noted as I was building out a clean install for the LCA SimpleBot:

• WPA config assumes a wifi connection. I was building on cabled network and it wouldn't let me skip (got past it but might be worth making it skippable).
• I ran the PiLeven script per here to make ttyS99 available: http://www.freetronics.com/pages/pileven-getting-started-guide#.VHAyVXWUfrc
• I also installed inotool (based on install notes here: https://github.com/amperka/ino#installation) as that seems to build things really well from the testing I've done and makes good guesses as to boards etc. (It also requires picocom).

You're doing a global install of johnny-five etc. This has some known issues in terms of version management in moving node modules and it also makes it much harder to run the examples (as they aren't in a project folder). You get a warning about this in the script output:

gyp WARN EACCES user "root" does not have permission to access the dev dir "/root/.node-gyp/0.10.33"

I'd remove these as they can all be installed in user space very easily. If you keep them then

Needs to go to raspi-io which is the package.

Once we deploy the LCA SB code it will be as simple as a git clone && node install so that should be cool for that side and pull in all the other package deps anyway.

Some other things I installed:

• pip (python package manager) apt-get python-pip && pip install -U pip
• virtualenv (python sandboxed environments) pip install virtualenv virtualenvwrapper

Hi there,

I configured my RaspberryPi with 2013-07-26-wheezy-raspbian.img onto a new SD card (freshly wiped)

In order to find the update script I used a Wi-Fi connection setup with WPA2/PSK for my home connection, using the WiFi config on the desktop of the fresh install.

I ran the first script with no issues, the second script asked my to input the wifi details, and I entered the exact same details again. the wifi would not connect after that, and could not be reset using the WiFi config on the desktop, it failed with message (Could not get status from wpa_supplicant). I had to use a wired connection to get the pi back on the network, a few restarts and ran the WiFi Config again, same settings overwritten and it's back working again

Mark

1. Must work stand alone
2. Should allow upgrade
3. Should latest version by default

For LCA, Nodebot days etc it's useful to provide students with a standard image with all the tools etc
required for session.

Proposed solution

On boot look for a file on /boot that contains a hostname
to be used.
If the file is not present do nothing.

NB File may be extended in future for other values

When the installion script runs, it could offer to install a mechanism for checking if an update / upgrade has occurred in the last "n" days. This mechanism would be checked when someone logs in (as the "pi" user) ... and if they want, will run an update / upgrade in the background.

Some packages are installed from tarballs or build from source. This is not ideal.

@geekscape said:

echo '# Setup for AVR compiler ' |sudo tee /etc/profile.d/avr.sh
echo 'PATH=$PATH:$AVR_PREFIX/avr/bin' |sudo tee -a /etc/profile.d/avr.sh

I believe that this writes $AVR_PREFIX literally in the file /etc/profile.d/avr.sh

Problem is that next time you login, the environment variable $AVR_PREFIX isn't set.

Instead of using Bash scripts it might be better to use a proper (but simple) config tool
