aitendo の FSTN液晶モジュール(128x64/SPI)[C128X64SPI-12P-M] を KL25Z につないでみました。今のところ、ドット、ライン操作までしか用意できていません。コントローラ仕様によるとデバイスからデータを取得することができるのですが、シリアル(SPI)ではできないことになっているため、フレームバッファは自前で持っています。テスト用にドラゴン曲線を表示させてみました。

ところで aitendo の商品説明ページ中の FPCケーブル取り付け例の写真は誤っていました(修正された模様)。また、キャリーボードでの LCD とバックライトの GND と電源は直結されているようです。ついでにサンプルのコードでのフレームバッファの使い方にも誤りがありますからドット単位で操作する場合には注意が必要です。

2014.03.12
q61.org さんの Chibimo 表示器として使えるようにしてみました。ドラゴン曲線を描いた後、ホストからの Chibimo データを処理します。KL05 とトラ技 ARM ライタ基板でも動作を確認していますが、Chibimo として使うには USB シリアルの使える KL* が良いでしょう。
