Anaesthetix 0:978110f7f027 1 /* Title: wait
Anaesthetix 0:978110f7f027 2 * Generic wait functions.
Anaesthetix 0:978110f7f027 3 *
Anaesthetix 0:978110f7f027 4 * These provide simple NOP type wait capabilities.
Anaesthetix 0:978110f7f027 5 *
Anaesthetix 0:978110f7f027 6 * Example:
Anaesthetix 0:978110f7f027 7 * > #include "mbed.h"
Anaesthetix 0:978110f7f027 8 * >
Anaesthetix 0:978110f7f027 9 * > DigitalOut heartbeat(LED1);
Anaesthetix 0:978110f7f027 10 * >
Anaesthetix 0:978110f7f027 11 * > int main() {
Anaesthetix 0:978110f7f027 12 * > while (1) {
Anaesthetix 0:978110f7f027 13 * > heartbeat = 1;
Anaesthetix 0:978110f7f027 14 * > wait(0.5);
Anaesthetix 0:978110f7f027 15 * > heartbeat = 0;
Anaesthetix 0:978110f7f027 16 * > wait(0.5);
Anaesthetix 0:978110f7f027 17 * > }
Anaesthetix 0:978110f7f027 18 * > }
