Hi Grr,
Could you please test your driver with the following application:
/****************************************************************************
* hello_main
****************************************************************************/
int main(int argc, FAR char *argv[])
{
char name[32];
int age;
printf("Inform your name: ");
scanf("%s", name);
printf("Your name is: %s\n", name);
printf("Inform your age: ");
scanf("%d", &age);
printf("Your age is: %d\n", age);
return 0;
}
Currently the outout is printed this way:
Inform your name: Your name is: Alan
Inform your age: Your age is: 30
It didn't echoed the name and age while the user was typing and didn't
print the line break.
BR,
Alan
