saadc called inside app timer not started

[schef]

Hi guys. I'm trying to measure my battery. I'm testing my function from main and it works. The procedure looks like this:

• saadc init
• sample data
• saadc uninit

But when i try to execute the same from app timer it hangs. Is there some kind of priority issue?

Which SDK version are you using? Yes, it could likely be a priority issue. Can you post the code snippets where you initialize the SAADC? The SAADC_CONFIG_IRQ_PRIORITY should be set set to 7 if you're using SDK v12.x.x or newer.

Hi, i have changed the SAADC priority to 6 and TIMER3 which is my instance to 6. And now it works! Do you think this is ok? I use SDK 13.0.0.

Yes, as long as its below 5 you should be O.K.
