'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, 
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.
