Example for getting and setting rtc time using app using nrf52832

[Rajbir Singh]

Hello,

I have just started learning nrf. I have an nrf52832 board and I want to get and set time using app.

I have seen this https://devzone.nordicsemi.com/f/nordic-q-a/57827/nrf5-calendar-example-questions

but haven't got much.

Please suggest me some examples.

Thank you in advance

Do you have experience with any other microcontroller(s)? with programming in general?

Please be more specific - what help do you feel you need that you feel isn't in that example?

I am an Arduino programmer, just started learning nrf a few days ago.

I am confused about how to set the path of the project.

If you show me an example of how to set the path if I want to use any example from nordic.

For example, I want to use this  https://devzone.nordicsemi.com/f/nordic-q-a/57827/nrf5-calendar-example-questions

but when I am making build its showing

Building ‘nrf_calendar_pca10040’ from solution ‘nrf_calendar_pca10040’ in configuration ‘Release’

I think its linker error but i am not sure how to remove this.

Have you studied the links I provided?

There's a lot there, but they cover what you need to know.

You should start with the SDK examples before going "off-piste";  I would suggest that you start with ones which don't use a SoftDevice; ie, no Bluetooth.

If you've not done "conventional" C programming before, it might be better to start with a "conventional" microcontroller, rather than nRF.

Alternatively, there is an Arduino Core available for nRF (though it's a 3rd-party effort - not supported by Nordic).

The nRF SDK, etc, does assume that you are already a competent embedded C developer.

Yes I have tried the examples and they are working, but i don't the functions in nrf and I am familiar with c programming. I have done almost  all the examples of the peripheral present in SDK 17.0

Hi

Can you explain what you mean about the following?

 What exactly are you struggling with here? Do you see this error when trying to build and run the nrf-calendar-example out of the box? To compile it, clone the repository in the [SDK]/examples/peripheral/ folder in SDK v16.0.0.

What nRF52832 board are you using? Is this a Development Kit or some third party board? The nRF Calendar example is only designed for and tested with the nRF52832 and nRF52840 Development Kits.

Best regards,

Simon
