gpiote config for PWM with softdevice

[Inspectron]

I need a PWM signal as outoput from the nRF51-DK. And I do need the softdevice. So I decided to pick the code from the nrf51-pwm-library-master and add it to my project(SKD 8.1).

The problem is, when I add the nrf_pwm.c file to my project I will get these errors:

Error: L6218E: Undefined symbol nrf_gpiote_unconfig (referred from nrf_pwm.o).

Error: L6218E: Undefined symbol nrf_gpiote_task_config (referred from nrf_pwm.o).

nrf_gpiote_unconfig and nrf_gpiote_task_config are defined in the nrf_gpiote.h file.

The nrf_gpiote.h file from SDK 7.0 is not the same as for 8.1.

Is there a pwm libray for SDK 8.1 available?

If not I will place the project in the SDK 7.0 then the error should be solved.

There is a pwm library in SDK 8.1 located in components/libraries/pwm. However, note that there is an issue there which we are currently working on: https://devzone.nordicsemi.com/question/39809/sometimes-pwm-signal-is-reversed/

[Inspectron]

Great! thank you. At the beginning its not a problem, if the signal is reversed. And I will use only one channel. So I think the issue should not be a problem for me now

[Radoslaw Koppel]

The problem would also appear in single channel mode. It is actually resolved in answer to the question linked above.

[Inspectron]

I know. Its working on my application. Thank you for the support.
