c - 在 Cygwin 中使用 NCurses 扫描 USB 设备的输入

Question

在学校实验室工作，我们必须从 PS4 Controller 获取陀螺仪值，并使用 C 语言通过 Cygwin 在 NCurses 中在屏幕上移动头像。目前，我有一个 scanf() 语句扫描来自PS4 Controller 在正常的 Cygwin 窗口/程序中工作正常，但我知道 NCurses 不使用 STDIN，因此 scanf() 数据不会在 NCurses 窗口中更新。有谁知道我必须在程序中使用什么函数或如何在命令行中通过管道传递它？谢谢!

我当前使用的命令:

 ./ds4rd.exe -d 054c:09cc -D DS4_USB -t -g -b | ./lab8.exe 80

主要代码:

// Main - Run with './ds4rd.exe -t -g -b' piped into STDIN
int main(int argc, char* argv[])
{
    int t,b_Triangle, b_X, b_Square, b_Circle;
    double g_x, g_y, g_z;
    if (argc <2) { printf("You forgot the difficulty\n"); return 1;}
    int difficulty = atoi(argv[1]); // get difficulty from first command line arg
    // setup screen    
    initscr();
    refresh();

    // Generate and draw the maze, with initial avatar
    srand(time(0));
    int colAvatar, rowAvatar;

    rowAvatar = 0;
    colAvatar = rand() % NUMCOLS;

    generate_maze(difficulty);
    draw_maze();
    draw_character(colAvatar,rowAvatar,AVATAR);

    // Read gyroscope data to get ready for using moving averages.    



    // Event loop
    do
    {

        // Read data, update average
        noecho();
        scanf("%d, %lf, %lf, %lf, %d, %d, %d, %d", &t, &g_x, &g_y, &g_z, &b_Triangle, &b_Circle, &b_X, &b_Square);

        // Is it time to move?  if so, then move avatar
        sleep(1);

        rowAvatar += 1;

        if(g_x > 0){
            colAvatar -= 1;
        }
        if(g_x < 0){
            colAvatar += 1;
        }

        MAZE[rowAvatar][colAvatar] = EMPTY_SPACE;
        MAZE[rowAvatar][colAvatar] = AVATAR;
        mvaddch(rowAvatar,colAvatar,EMPTY_SPACE);
        mvaddch(rowAvatar,colAvatar,AVATAR);

        refresh();
        fflush(stdout);



    } while(b_Square != 1); // Change this to end game at right time 

    // Print the win message
    endwin();

    printf("YOU WIN!\n");
    return 0;
}

您可能想到的是scanw :

int scanw(const char *fmt, ...);

convert formatted input from a curses window
