In an effort to try and determine why FreeRTOS tickles idle is consuming more current than tick mode with an idle task, see this post devzone.nordicsemi.com/.../, I noticed that our project still had build time define for NRF52_PAN_28. I removed this define and the quiescent current increased to ~1.5mA. The waveform shows a pronounced offset like a peripheral or clock is being left on. I will post a waveform comparison tomorrow.
Notes:
- ADC is a FreeRTOS task which has a period of ~160ms.
- The intent is to sample 8 channels via scan mode
- The task also uses the internal temperature sensor
- SDK11, S132 v2.0.0.0, chip is QFAABB (Rev C)
