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 }
