CC2650: RTC example project

HS FAE Germany

Part Number: CC2650

Hello,
customer wants to wake up the CC2650 every 12hr. What is the best way? Using 2 chained timers or the RTC? Do we have an RTC alarm example project?

Holger,

There is an example of going into a low-power mode with a wakeup timer in this guide: https://dev.ti.com/tirex/explore/content/tirtos_cc13xx_cc26xx_2_21_00_06/docs/Power_Management.pdf

See section 3.3: CC13xx/CC26xx Reference Power Policy

Daniel

Hello Daniel,
customer told me that he don't want to go into low power / standby mode. He just need a 12hr timer. The standard timer is 32bit and can't do it. Therefore the idea was to use the 70bit RTC timer.

Holger,

There is an example showing how to use a real-time clock here: https://dev.ti.com/tirex/explore/node?node=AEltX787--5l4wqwg..jhw__Drd3Vmn__LATEST

You can also reference the Clock module (https://dev.ti.com/tirex/explore/content/tirtos_cc13xx_cc26xx_2_21_00_06/products/bios_6_46_01_37/docs/Bios_User_Guide.pdf) Specifically, the Seconds module might work for this application.

Regards,

Daniel
