Twe Liteの接続と起動に関して痛い目にあったのでメモ。

リモート制御に時間が必要なるけれどインターネットの接続環境が用意出来なかったので今回はRTCを使用。
Amazonで800円くらい。

こちらのサイトを参考にインストール。

https://learn.adafruit.com/adding-a-real-time-clock-to-raspberry-pi/wiring-the-rtc

結線後に
$ sudo apt-get install python-smbus
$ sudo apt-get install i2c-tools
i2c-toolsをインストール（インストールしていなければ）
$ sudo i2cdetect -y 1
ちゃんとつなげてれば0x68の場所になんか表示されるはず。
$ sudo modprobe rtc-ds1307
$ sudo bash
echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
exit
下記のコマンドでハードウェアから読めるか確認。
sudo hwclock -r

sudo nano /etc/modules
の中に
i2c-bcm2708
i2c-dev
rtc-ds1307
を追加。

$ sudo nano /etc/modprobe.d/raspi-blacklist.conf
の中の二行をコメントアウト。
#blacklist spi-bcm2708
#blacklist i2c-bcm2708

rc.localに下記を追加して起動時に時刻を合わせるように調整。
screenでごにょごにょやってるのは起動時にFTDIのデバイスを何かが掴んでることがあるみたいなのでプロセスを一旦殺してます。
おまじない見たなもの。
$ sudo nano /etc/rc.local

echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
sudo hwclock -r
screen -d -m -S AAA /dev/ttyUSB0 115200
screen -r AAA -X kill
exit 0

アプリを自動的に起動させるため実際にはexit 0の前にアプリをrunさせる用に設定してます。
そんな感じ。

sudo chmod u+x seriaTWE
sudo update-rc.d serialTWE defaults

Falls

notempo — Wed, 05 Feb 2014 07:40:42 +0000

This “A Falls” is the latest installation art presented by noTempo. It was displayed at gymnasium of a primary school in Zushi city as part of ZUSHI Media Art Festival 2013.

In this installation, infrared camera detects an image of a person’s movement which then gets analyzed simultaneously and reflected on the picture.
The software used consists of three applications which are “for image analysis from infrared camera”, “for generating visual images”, and “for mapping”. And each application exchanges the data with TCP communication, Syphon, and others.
There are four images with themes of “In the sea (blue)”, “In the forest (green)”, “Wheat field (orange)”, and “Autumn forest (red)” which are put together to continue in a loop. Then the application “for generating visual images” is used to add visual images of waterfall and leaves falling from above as well as others like school of fish, while the application “for image analysis from infrared camera” allows us to blow the wind or change the gravity in the virtual world.
Also, Duration is used for managing the whole scene which makes it easy to change the length of the scene and perform other scene managements.

Send syphon image to another Computer

ofPublishScreenアドオンを使って
syphonで受け取った画像を別のMac上で再生するアプリにまとめてみた。
1000MBaseの有線LANで1920*1080でも50fpsでてる。
でも、元のアプリ側の処理が重いと遅延が出る模様。

設定を変える場合はdataフォルダ内のini.txtをいじる。
url [ set address to pull jpg file ]
port [ port number ]
appName [ set app name to get syphon ]
h [ fbo size y ]
w [ fbo size x ]
