72歳の... STM32H750で16bitパラレルTFTディスプレイ、タッチ機能もグッド。少しだけ不満点が。

Posted at

　最近購入した「WeAct MiniSTM32H750VBT6」ボードと悪戦苦闘してます。

その中でこのサイトhttps://github.com/offpic/GUI-TFT-STM32-NT35510
を見つけ、手持ちの

4inch 800x480 Display MAR4018

と「BlackPill」で試したところ動くではないですか！気をよくしてこちらのボードでもやってみました。
H7_nt35510.jpg

表示に関してはESP32、RaspberryPicoなどで出来てました。今回初めてタッチ機能もサクサク使え大収穫でした。
　環境・構成等は

１．Windows11 25H2
２．STM32CubeIDE 2.2.1
３．STM32CubeMX 6.17.0
４．STM32CubeProgrammer 2.22.0
５．ST-Link V2（アマゾンで購入の廉価品）
６．WeAct MiniSTM32H750VBT6（アリエクで購入）
７．4inch 800x480 Display MAR4018（NT35510, XPT2046）

　評判通りSTM32CubeIDEがVer2になって使いづらくなってました。

最初に、STM32CubeMXでプロジェクトを作り、
STM32CubeIDEのワークスペース内に作成しておいたフォルダーに保存させる、
その時にSTM32CubeIDEを起動させる

という手順で、何とか出来ました。
STM32CubeMXで、RCCを

クロックコンフィグレーションは最高速の480MHzに設定。GPIOは

GPIO1.jpg
としました。サイトのオリジナルでは中途半端に「USBデバイスとして認識される」ので、以下のように変更しました。

T_CS　  PC1
T_MISO　PC2_C

ビルドエラーを解消するため、

１．GUI.ｈ に　void LCD_Rect_Round(uint16_t x, uint16_t y, uint16_t length, uint16_t width, uint16_t r, uint8_t size, uint32_t color24);//追加
２．nt35510.h　に　void WriteData(uint16_t data);// 追加

Flashメモリが128kBしかなく、binファイルを作ってくれません。なので、フォントも使用するものだけにしたうえ、main.cの画像を表示する部分はコメントアウトしました。

//TFT_Draw_Bitmap(40, 40, 259, 140, ST);    //ST MICRO
//TFT_Draw_Bitmap(330, 35, 150, 150, QR);   //QR CODE
//TFT_Draw_Bitmap(540, 280, 170, 198, ON);  //not build
etc.

これで、binファイルのサイズが68KBとなりました。長くなりますが、main.cの必要なソースは以下になります。
