[gainer] Python

Hossy’s Workshop: Gainerというのがあるようだ。

でも、Pythonで使っている様子。

まあ、試してみるか。

PyGainer

• comms/py-serial

おお、これは動いてるな。

まだ、LEDしかつないでないので、出力だけ。

[gainer] Perl

Perl用Device::Gainerモジュールを書いてみた

• devel/p5-Class-Accessor

うーん、どうもSerialProxy専用のコーディングだと思う。

[gainer] Ruby again

comms/ruby-serialportに変えたら、動いたっぽい。

相変わらず、LED出力だけのテスト。

fuji% cat gainer-test.rb 
require 'gainer-serial'

g = Gainer::Serial.new(ARGV.shift)

done = false
g.on_pressed = proc do
  done = true

end

[gainer] 構成変更

CdSとタクトスイッチを増やして、入力できるようにしてみた。

一応、rubyとpythonで動作を確認した。

以下は、rubyの分。

fuji% ruby gainer-test.rb /dev/ttyU0
press button to quit. led = on :0,Input: 0000,E7DAE3E8.
press button to quit. led = off:1,Input: 0000,E6D9E2E7.
press button to quit. led = on :2,Input: 0000,E6DAE3E7.
press button to quit. led = off:3,Input: 0000,E6DBE4E9.
press button to quit. led = on :4,Input: 0000,E6DBE4E9.
press button to quit. led = off:5,Input: 0000,E6DBE4E9.
press button to quit. led = on :6,Input: 1000,E6DEE6EC.
press button to quit. led = off:7,Input: 1000,E6DDE6EA.
press button to quit. led = on :8,Input: 1000,E6DBE3E8.
press button to quit. led = off:9,Input: 1000,E6DAE2E8.
press button to quit. led = on :10,Input: 1000,E6DAE3E8.
press button to quit. led = off:11,Input: 1000,E6DBE3E8.
press button to quit. led = on :12,Input: 1000,E6DBE3E8.
press button to quit. led = off:13,Input: 1000,E6DBE3E7.
press button to quit. led = on :14,Input: 1000,CCD2DAD8.
press button to quit. led = off:15,Input: 1000,8F888A8A.
press button to quit. led = on :0,Input: 1000,A7959EA4.
press button to quit. led = off:1,Input: 0000,BE898FA0.
press button to quit. led = on :2,Input: 0000,E6D5E0E5.

いい感じだ。

[gainer] その他の情報

• processing + jythonでGainerを制御する

開始。

とりあえず、体の内側を彫ってみた。
