STM32G031J6M6とmbrd-os 6でタイミング系を使うと落ちるのでちょつとだけ頑張ったレス

目的
なんか気持ち悪い
進捗か止まっていたのは、タイミング系のせい?
なんか頑張ってみる
今のところ原因不明で継続テーマ

        ThisThread::sleep_for(5s);

Timer t;


int main()

省略

    t.start();

    int ii;
    while(1) {

        auto s = chrono::duration_cast<chrono::seconds>(t.elapsed_time()).count();
        sprintf( buf, "%llu\r\n", s );

        ii=0;
        while(buf[ii] != 0) {

            ii++;
            
        } //while

} //main

で

タイマーだとタイミングを取れそう
翻訳では、騒がしいタイマーと言ってあまり良くないらしい
割り込み系のタイマーを頑張ってみよう

stm767ziを使うと上手く動く
