Using PPI with app timer

[Aamir]

Hi,

I am using NRF52 SDK 15.3 on nrf52840 Preview DK

I am using BLE to transmit data, I want to use PPI to get readings off of SAADC but using 'app timer' instead of TIMER

How can I go about doing that, as I don't see any get_event_address function for app timer ?

app_timer is a software timer build on top of RTC peripheral so it's not a good option to use as a source for PPI since you will get COMPARE events on every timeout of any timer used in the application. I you want to trigger SAADC using PPI you can use another RTC instance (RTC2 is not used by SDK) or TIMER instance.

Do you mean SD (soft device)?

I meant that RTC0 is used by softdevice, RTC1 is used by app_timer and RTC2 is available.

Thanks!
