'NRF_PWM2' undeclared here (not in a function); did you mean 'NRF_PWM0'

[gayathri2050]

I'm in the process of integrating PWM into my project, which uses SDK 17.1.0.

I've added the below lines in my config file

#define NRFX_PWM_ENABLED 1

#define NRFX_PWM0_ENABLED 1

Additionally included the following headerfiles 

nrfx.h
nrf_pwm.h
nrf_gpio.h
nrfx_log.h
nrf_egu.h

However , during compilation I'm getting a series of errors

'NRF_PWM1' undeclared here (not in a function); did you mean 'NRF_PWM0'?

'NRFX_PWM0_INST_IDX' undeclared here (not in a function); did you mean 'NRFX_PWM_INSTANCE'?

'NRFX_PWM1_INST_IDX' undeclared here (not in a function); did you mean 'NRFX_PWM_INSTANCE'?

'NRFX_PWM2_INST_IDX' undeclared here (not in a function); did you mean 'NRFX_PWM_INSTANCE'?

How do I fix this?

Could this issue possibly related  to the SDK version I'm using?

Hi Gayathri, 
it seems that you have the seems issue as this: RE: 'NRFX_PWM0_INST_IDX' undeclared here (not in a function); did you mean 'NRFX_PWM_INSTANCE'? 

Could you try to follow what described there to add PWM0_ENABLED 1 and PWM_ENABLED 1 in to sdk_config.h ?

Hello Hung Bui,

These lines had already been added to sdk_config.h; however, it still throws the same errors.

#define PWM_ENABLED 1
#define PWM0_ENABLED 1

Hi Gayathri, 
Have you included nrfx_pwm.h ? 
I saw that you included nrf_pwm.h but not nrfx_pwm.h
If that doesn't help you may want to try compare your project with the pwm_driver project.
