用意するもの

これキー入力したいよね

スライダーが出来た所で
「あ、バーチャルキーボード作れそう」って事で作ってみた

ライブラリ作成

30% キーボードを作りたかったのですが　抵抗被膜式タッチパネルでは

キーを切り替える事が意外に難しいと判断し

11個 x 4段に色々仕込みました

色々自分で作ってみるのも面白いかも٩(ˊᗜˋ*)و

const char *_tcKey[_tcRow][_tcClm][_tcSft] = {
      {{"1", "!"}, {"2", "\""}, {"3", "#"}, {"4", "$"}, {"5", "%"}, {"6", "&"}, {"7", "'"}, {"8", "("}, {"9", ")"}, {"0", " "}, {"bs", nullptr}},
      {{"q", "Q"}, {"w", "W"}, {"e", "E"}, {"r", "R"}, {"t", "T"}, {"y", "Y"}, {"u", "U"}, {"i", "I"}, {"o", "O"}, {"p", "P"}, {"@", "@"}},
      {{"a", "A"}, {"s", "S"}, {"d", "D"}, {"f", "F"}, {"g", "G"}, {"h", "H"}, {"j", "J"}, {"k", "K"}, {"l", "L"}, {";", "+"}, {"sp", nullptr}},
      {{"sf", "SF"}, {"z", "Z"}, {"x", "X"}, {"c", "C"}, {"v", "V"}, {"b", "B"}, {"n", "N"}, {"m", "M"}, {",", ","}, {".", "."}, {"en", "EN"}},
    };

応用例

このモジュール群は以下で使ってます是非ご参照くださいませ٩(ˊᗜˋ*)و

LoRaPager

残務と今後の考察

キーを押すのにテクニックが必要とか

でも何事もやってみないと分からないことだらけのこの人生

やはり横長の画面で使った方がいいかも

linux のコンソールみたいで良いですね(棒)

さいごに

ご清聴ありがとうございました

押しにくい～
