【ESP desktop IoT化：動作 】　赤外線＆有線で、モニターセレクタ、USBセレクタ、照明、エアコンをandroid端末からWifi経由で制御するモジュール作成

の続き。

【書き込みアダプターの作成】
ESPに書き込む際に、IO0をGNDに落としながらリセットをGND落として書き込みモードにして・・と書き込み儀式があるのでスイッチを使うが、書き込み時以外には使わないので、本体のボードには載せず、書き込み用のモジュールを作成してあげて書き込みを行う。


IO16のピンに緑のLEDをオンボードで用意しているが、”書き込み儀式”を行うと、点灯。書き込みモードに入ったサイン。この状態で、書き込みを実施。完了すると消える。

【赤外LED】
XHコネクタ

を圧着し、反対側にはLEDはめるソケットを半田で固定。

カソード、アノードが分からくならないために、赤いマークをケーブルには入れている。
２チャンネル用意しているのは、エアコンはデスクと反対側にあるし、結構距離があるので、方向や位置を反応する方向に向ける必要がある。かたや、デスク回りの照明のLED受光部やHDMIの切り替えの受光部は別のエアコンとは真逆だしという理由。

【UEBセレクター】
で既に作っているので、そのまま。

}



一応動作は、ちゃんとしていて、HDMIの切り替え、USBの切り替え、LED照明のON/OFF、エアコンの操作、あとマクロ的にボタン一つで、登録したキーボード出力ができる。



３Dプリンターで固定治具を打ち出して、USBセレクタ、MDMIセレクターを固定。


作成した基板は、アクリルで簡易的なケースを作成してて、固定。
LEDは、３DプリンターでLEDを固定する治具で固定してＩＲ（赤外線受光部）の前に固定。

Attiny85とAQM0802A(LCD)のI2C接続

Attiny85とAQM0802A(LCD)のI2C接続 以前に 、ブレッドボード上でArduinoにAQM0802を接続して文字を表示できたので、今度はAttiny85での表示。 Arduino　UNO,Nanoだと"Wire.h"を読み込むんだがAttinyでI2Cを扱うには、”TinyWireM"を読み込む。 またLCDで提供されているST7032.hの中身とかも変更する必要がある。 そこは自分でやらなくても、非常に先人の方々がまとめてくれている。（ ここと か） ・はまった点症状 AttinyにちゃんとISPから書き込みができているのに液晶に何も映らない。 かと言って同じスケッチをNanoに書き込み”Wire”に戻してあげて接続すると動く。 つまり、スケッチが悪い訳でもないし、液晶が壊れている訳でもない。 VCCのラインにスイッチを設けてやって、スイッチをなぜかダブルクリックすると液晶が映る。一度映ると消える事はないが、たまに映らない事があり不安定・・・ なぞのままである。 でAttinyが表示器を手にいれられた。 でスケッチを書き換えて温度計としてみる。 サーミスタのテストをしたとき のスケッチとマージして、Attiny85で計測して表示する。 26度付近の室温を示して、サーミスタを手でつまむと3４度とかまですぐ上昇。 温度表示まではできた。 //this is a test for attiny85 thermistor //measured temperature is displayed on LCD AQM0802A  //  PB5[  ]VCC  //  PB3[  ]PB2 SCL  //  PB4[  ]PB1  //  GND[  ]PB0 SDA #include <TinyWireM.h> #include <ST7032.h> ST7032 lcd; const int PIN_ANALOG_INPUT = 4; const float V5V = 5.0;//measured voltage +5V p...

CH9329で日本語キーボード109で正しく表示する方法

-
イメージ
 CH9329を使う際は、 しごぶさんのCH9329のライブラリーをありがたく利用させていただいている。 https://github.com/shigobu/CH9329_Keyboard しかし、デフォルトのままでは、英語のＵＳキーボードの出力しかできない。正確には、ドイツ語やスペイン語といったキーボードの配列が入っているが、肝心な日本語キーボードが入っていない。 そこで、日本語キーボードへの対応をして、すべてのキーを入力できるようにする手順を残しておく事にする。 まず、ライブラリーのフォルダーに、KeyboardLayout_jp_JP.cppという名前のファイルを作成する。 中身は日本語のキーボードにあわせて以下にした。 /*  * Japanese keyboard layout.  */   #include "KeyboardLayout.h"   extern const uint8_t KeyboardLayout_jp_JP [ 128 ] PROGMEM =  {     0x00 ,        // NUL     0x00 ,        // SOH     0x00 ,        // STX     0x00 ,        // ETX     0x00 ,        // EOT     0x00 ,        // ENQ     0x00 ,        // ACK     0x00 ,        // BEL     0x2a ,        // BS   Backspa...
