私は何人かの友達とエレクトロニクス/プログラミングを学んでいます (そして教えようとしています)。タスクのために、ランチパッドを使用して LED キューブを作成することにしました。
私たちが遭遇する問題は次のとおりです。
アニメーションの場合、それらを 2 次元配列に格納します。配列を定数として定義するとエラーが発生します
この配列を RAM に配置したくありません。利用できる領域があまりないからです。
編集:コードについては以下を参照してください
これが正しい場所に投稿されることを願っています。
いつでも(私は思う?)配列を変更していません。それらはすべて手動で一度設定され、ループされます。何が (暗黙的に?) 変換されようとしているのかわからない
必要に応じて情報:
MSP430G2553 16kB フラッシュ 0.5kB RAM
ご協力いただきありがとうございます
更新: HansPassant が、エラーが表示される理由を教えてくれました。しかし、まだ RAM オーバーフローが発生します (明らかに、フラッシュに保存されていませんか?)
私が試したもう 1 つのことは、#define RON (Row ON) の代わりに、const としても宣言しました。(そのため、アニメーション配列が作成されたときに、定数のみで明示的に作成されました)フラッシュに保存することを望んでいました。
必要に応じて、コード全体を次に示します。
