Serial (USB)¶

Serial is used to print from and read data into the robot.

Sample Code¶

#include <dragonfly_lib.h>
/*
 * Prints to and reads from serial.
 */
void usb_sample()
{
    usb_init(); // must be called before using any usb code

    usb_puts("Pick a letter from a to z"); // prints out "Pick a letter from a to z" 
    usb_puts("\r\n"); // prints a newline
                      // now, the next thing that is printed will be on the next line

    int letter = usb_getc(); // puts the next character that the user types into the variable letter

    usb_puts("You picked "); // prints out "You picked " 
    usb_putc((char) letter); // prints the character that the user typed
    usb_puts("\r\n"); // prints a newline
}
