| uint32_t dn_time_ms(void):
void dn_sleep_ms(uint32_t milliseconds); |
These functions allows the QSL to perform timing, schedule tasks and sleep to save power. - time_ms: Simply needs to return time in milliseconds. The absolute value is irrelevant; as long as the time returned from subsequent calls will differ by the actual time passed between them.
- sleep_ms: Make the CPU sleep (or simply delay) for the set number of milliseconds.
- . If power consumption is not a big concern, an alternative is to simply add a delay.
| Warning |
|---|
| Make sure time_ms counts to the full 32 bit range (i.e. up to 4294967295 or 0xFFFFFFFF) before it wraps around to ensure correct behaviour; the QSL will trigger a timeout too early if it is scheduled right before an unexpected wrap around. |

| title | dn_watchdog.h |
|---|
| void dn_watchdog_feed(void); |
This function allows the QSL to make sure any watchdog in the user application is fed during processes that can take some time (e.g. searching for a network).
- watchdog_feed: Feed any watchdog that might be implemented in the platform; simply use stub function if none.
