antbig 0:ad97421fb1fb 2 * Generic wait functions.
antbig 0:ad97421fb1fb 3 *
antbig 0:ad97421fb1fb 4 * These provide simple NOP type wait capabilities.
antbig 0:ad97421fb1fb 5 *
antbig 0:ad97421fb1fb 6 * Example:
antbig 0:ad97421fb1fb 7 * > #include "mbed.h"
antbig 0:ad97421fb1fb 8 * >
antbig 0:ad97421fb1fb 9 * > DigitalOut heartbeat(LED1);
antbig 0:ad97421fb1fb 10 * >
antbig 0:ad97421fb1fb 11 * > int main() {
antbig 0:ad97421fb1fb 12 * > while (1) {
antbig 0:ad97421fb1fb 13 * > heartbeat = 1;
antbig 0:ad97421fb1fb 14 * > wait(0.5);
antbig 0:ad97421fb1fb 15 * > heartbeat = 0;
antbig 0:ad97421fb1fb 16 * > wait(0.5);
antbig 0:ad97421fb1fb 17 * > }
