Counter Alarm Sample
This sample provides an example of alarm application using counter API. It sets an alarm with an initial delay of 2 seconds. At each alarm expiry, a new alarm is configured with a delay multiplied by 2.
In case of 1Hz frequency (RTC for example), precision is 1 second. Therefore, the sample output may differ in 1 second
This sample requires the support of a timer IP compatible with alarm setting.
