Note: The function wait is deprecated in favor of explicit sleep functions. To sleep, replace wait with ThisThread::sleep_for (C++) or thread_sleep_for (C). To wait (without sleeping), call wait_us. wait_us is safe to call from ISR context.

The wait_us and wait_ns functions provide precise wait capabilities. These functions spin the CPU to produce a small delay so they should only be used for short delays. Any delay larger than a millisecond will affect power and multithread performance, and block the platform deep sleep for the entire duration. Therefore, spinning for millisecond wait is not recommended, and ThisThread::sleep_for should be used instead.

Wait function reference

 DigitalOut heartbeat(LED1);

 int main() {
     while (1) {
         heartbeat = 1;
         heartbeat = 0;
