SDK13 can not find sdk_config.h

[Leila]

Hi,

I am trying to add saadc sample code to ble_blinky sample code. But I faced a problem. It seems that the sdk_config.h file is not recognized by the sample code. and I got this errors:

"TIMER_DEFAULT_CONFIG_FREQUENCY" is undefined "TIMER_DEFAULT_CONFIG_MODE" is undefined "TIMER_DEFAULT_CONFIG_BIT_WIDTH" is undefined "TIMER_DEFAULT_CONFIG_IRQ_PRIORITY" is undefined

I am using SDK13 sample codes, on nRF52840-PDK.

Could you please let me know about possible ways to solve the problem?

Thank you, Leila

Yes, the softdevice use TIMER0 peripheral and will block access to this for the application. You need to enable another TIMER in sdk_config.h and initialize the timer using NRF_DRV_TIMER_INSTANCE(1);.
