APP_PWM_INSTANCE error in SDK12.2.0

[Nilesh Bhavsar]

Hi,

I am using SDK 12.2.0 with secure DFU service.i want to use pwm in my code.And i init pwm with APP_PWM_INSTANCE(PWM1,1),then i get an error:identifier "TIMER0_ENABLED" is undefined.

Samething i have done in SDK11 by enabled timer is SDK Folder/component/driver_nrf/config/nrf_drv_config.h file.

But i have not found any nrf_drv_coonfig.h file in SDK12.2.0.

Hi,

With the release of SDK version 12 a new SDK configuration header file to manage static configuration of an application was added. This header file is called sdk_config.h and replaces the nrf_drv_config.h. If you are using Keil, you should try to use the Configuration Wizard. Also note that since the SoftDevice uses TIMER0, I would recommend using e.g. TIMER1 instead.

Configuration Wizard:

I am done with above changes. Now, my TIMER0_ENABLED error is gone but now i am receiving new error: Undefined symbol app_pwm_channel duty_set (referred main.o) and same for app_pwm_enable & app_pwm_init.

I am already set the path of app_pwm.h and add include the header file into my main.c

You also need to enable PWM in sdk_config.h. Under nRF_Drivers you need to set PWM_ENALBED
