Timeslot observer example SWI0_IRQn conflict

[cpignol]

Greetings,

SDK6.1 and Keil V5.12 I try to build the executable for Nordic GitHub project Timeslot Oberver example. I get an error that the handler SWI0_IRQHandler is multiple defined. Define in app_timer.c and define in main.c app_timerc. is part of nrf_libraries. In main.c SWI0 is used as Timeslot event interrupt (btle_scan_init(SWI0_IRQn) I have tried to use SWI1_IRQn for the Timeslot event interrupt so I can build the executable but I don't think it is the best way to solve this problem. Thanks, Claude

I think a separate software interrupt for the app_timer module is necessary due to the time sensitive nature of the module.

However, I do agree that the timeslot Observer example can provide some infrastructure to share the software interrupt so that it can be used by additional application modules.

Crossposting this in the github repo so it is tracked for closure by the developers.

Thanks for the answer. app_timer declares an SWI0_IRQHandler(). How to share the software interrupt in the application without redeclaring another SWI0_IRQHandler()? With the current version of this example, I can not link it, so I am curious how the developers of this example were able to generate an executable?

They most likely did not use the app timer in their example code. This will be fixed.
