Migrate Code Nrf51 to Nrf52

[iremino]

Hi guys, i was using nrf51822 s130 sdk, and now i am using nrf52dk s132 sdk. When i am using nrf_adc.h, all bitfields macro's get errors. It's bitfield macros doesn't match nrf52's bitfield macros because i am using nrf51's nrf_adc.h header. And i didn't find a nrf_adc.h header for nrf52 dk. Do you have any idea?

And if i don't use nrf_adc.h, i get this errors;

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_pwm_enable (referred from main.o).

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_pwm_init (referred from main.o).

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_pwm_uninit (referred from main.o).

I don't know is it relevant each other, do you have any idea how can i fix this errors?

Thanks

Thr nRF52 is significantly different from nRF51, and the SDK has moved on a lot.

It is unrealistic to expect that this "migration" will be just a few tweaks - it is a major porting exercise.

Probably the easiest approach will be to start with appropriate nRF52 examples, and merge-in your application-specific stuff ...

Hi, yes i started with nrf52 examples as you said, and trying to merge with my functions but how can i solve this adc.h problem i don't know

So you've got an SDK v15.3.0 ADC example working?

In that case, you must have all the necessary Nordic headers in place.

So you just need to add your own, custom-written application code - no more Nordic stuff.

yes i am doing all this too, but sdk15.3.0 doesn't have an adc header, it is a problem. maybe header name different for nrf52? 

And i can't find how this problems ; Undefined symbol app_pwm_uninit (referred from main.o). for nrf52, do you know how i can fix this errors?

You're missing the point!

You need to separate what is your application code - the stuff you've written yourself to achieve your goals - from the underlying driver code which Nordic provide just to make their hardware work.

This is basic software development stuff.

Using the SDK ADC example, you should be able to get the basic ADC drivers working, and giving you readings.

Your application code should then take these readings without worrying about where they came from.

Perhaps you need to take a step beck and re-organise your nRF51 code to separate your own code from the Nordic code ...

himm okey thanks for your help

We also have some documentation in order to migrate from the nRF51-series to the nRF52-series that you can take a look at.
