wait function

[wim]

Hi

during setup of a peripheral at startup, I need to add some wait periods in between steps of the setup. Is there some function like waitMS(int time) or something, that would make the processor wait during a number of milliseconds, without compromising the timeliness of the BLE stack? Or is there some other way of doing timed blocking functions ?

The alternative would be to split up the function into different steps - or states- , and re-enter the function with timer events. But that is just a lot more code. And also using an RTOS is somewhat overkill for this, as I would only use this during startup.

The header file "nrf_delay.h" has an in-line delay routine:

void nrf_delay_us(uint32_t volatile number_of_us)

and the declaration for

void nrf_delay_ms(uint32_t volatile number_of_ms);

If you are using Keil V5, with packs, you will find the source here:

C:\Keil_v5\ARM\Pack\NordicSemiconductor\nRF_Drivers\1.2.1\hal\nrf_delay.c

both the us and ms delay code are just spin loops.

Great! Thanks a lot.
