v2n-rtc-multi-alarm

What it shows

• Registering multiple rv3028c7_alarm_* callbacks against different sources (timer countdown, alarm match, weekday).
• The dispatcher fanning interrupts out to the right callback by INT-flag inspection.
• Battery-backed persistence: RTC keeps time across host power cycles via VBAT_BACKUP.
