nrf_pwm.h requesting includes for wrong device

[AmiguelS]

Hello! I'm trying to use the PWM on a board containing an nRF51822 device. However, simply including the nrf_pwm.h file multiple errors are trigered, such as the following (among other):

• sdk_11/components/drivers_nrf/hal/nrf_pwm.h:68:43: error: unknown type name 'NRF_PWM_Type'
• sdk_11/components/drivers_nrf/hal/nrf_pwm.h:80:37: error: 'PWM_INTENSET_STOPPED_Msk' undeclared here (not in a function)
• sdk_11/components/drivers_nrf/hal/nrf_pwm.h:312:45: error: unknown type name 'NRF_PWM_Type'

After seraching the SDK I noticed that these defines are available on the iles relative to the nRF52 devices. Since I'm using an nRF51 device, how should I procede?

The nRF51822 does not have a PWM peripheral. That was added as one of the nRF52 improvements. So it is appropriate that the register definitions are in the nRF52. Rather than using the hal based nrf_pwm, you can use the timer PWM library that worked on the nRF51 look at: nRF5_SDK_11.0.0\components\libraries\pwm
