Linuxで回路図を書こうとして探してたらこれを発見
>>
# aptitude install geda-gschem

でインストール（Debian)
http://www.mail-archive.com/geda-user@moria.seul.org/msg17056.html
ここからatmega168のデータを借りてくる
シンボルの作成は
http://www5a.biglobe.ne.jp/~nkgwtty/njaLinuxgEDA01.html#SYM_MK を参考にした。
とりあえず回路図： http://inajob.no-ip.org/dev/rakuchord_mobile/keykey.png
なんかうまく使いこなせてない感。とりあえず書いてみた。
画像書き出しの範囲指定がなんか微妙で上切れちゃった（スクロール位置と関係がある？）
CON1は後から書きこむ用のピンです。動作には使いません。
あとPS/2の配線は書いてないですが5番がCLK、6番がDATA
!!ソース
取り回しの関係でコメントが謎英語になってます。
breakってのはキーアップのことです。
PROGMEM使うつもりで使ってないのも あとで直す って思っててそのまま放置した跡です。
見苦しい点は少しずつ直していきます。
キーボードの周りはhttp://www.arduino.cc/playground/Main/PS2Keyboard このへん参考にした
!!!あれ？ 直したい！
- 1<<14 がなんで出てきたのか不明。まぁ周波数は合ってるから音はでるけど変な波形になる気が…？
- 普通に↑のライブラリを使ったほうがよさげ。 スキャンコードとASCIIの対応表とかパターン多そうだし…
