Question

Hello, 
 Just uVision 5.14 and SDK 7.2.0. Try to compile the blinky example and get the next error 
 ._build

 What's wrong?! 
 Thank you!!

Hi Daniel, 
 Have you make sure you referred to nrf_delay.h in the project setting. It's located in \components\drivers_nrf\hal. 
 The nrf_delay_us function is defined in that file.
