YY3568

Hi guys~
i want to using GPIO, UART of yy3568 with Unity3D.

Here is part of my Source
[DllImport(“libYY3568GPIO”)] private static extern int gpio_direction(int gpio, int dir);
[DllImport(“libYY3568GPIO”)] private static extern int gpio_set_edge(int gpio, int rising, int falling);
[DllImport(“libYY3568GPIO”)] private static extern int gpio_export(int gpio);
[DllImport(“libYY3568GPIO”)] private static extern void gpio_unexport(int gpio);
[DllImport(“libYY3568GPIO”)] private static extern int gpio_getfd(int gpio);
[DllImport(“libYY3568GPIO”)] private static extern int gpio_read(int gpio);
[DllImport(“libYY3568GPIO”)] private static extern int gpio_write(int gpio, int val);
[DllImport(“libYY3568GPIO”)] private static extern int gpio_select(int gpio);

int gpio_pin = 28;
// Start is called before the first frame update
void Start()
{
int res = gpio_export(gpio_pin); // I got Error at here, the return value is -1
Debug.Log(“gpio_export res = " + res);
gpio_direction(gpio_pin, 1); //and also i gor error " perror(“Couldn’t open IRQ file”);”
}

plz help me what i have to do, it is my first time to develop for embedded sys.

  1. Check if the open path is correct
  2. Check if the permissions are sufficient.

  1. Check if the open path is correct
    <=== i think this path is must be correct becaz the android 11 OS has installed by your company

  2. Check if the permissions are sufficient.
    <=== how can i get THE permission ?
    and i wonder if i have 100 of yy3568, i have to get all of those board permission by manually?
