nRF51_DK PCA10028 helloworld example

[irtiq7]

Hi,

I recently started learning to program nRF51 development kit. I followed most of the examples listed in the forums but I am unable to find a dedicated link which would give me a better understanding of controlling the GPIO pins of the development board. I tried using the user manual and ble_app_uart_pca10028 example but it does not give me a complete information on how the board is configured with the LED or push button. Could someone help me out understand this?

Thanks,

Have you tried looking at the gpio example in the SDK? E.g developer.nordicsemi.com/.../a00035.html

Hi, welcome to the community !

I understand it can be nerve-wrecking looking for some explanations. I would suggest you look at the examples that come with the SDK. I am assuming you have not looked at the guide, so first find the guide at your SDK location. Usually it is located at C:\Keil_v5\ARM\Pack\NordicSemiconductor\nRF_Examples\8.0.0\documentation\index.html. From there, you select "Peripheral SoftDevice S110" option which will open the comprehensive guide for the chip. On the left hand tab, there are many categories which will help you understand how the APIs and Data Structures are laid out. The documentation for the examples is located under the example tab. As for the example codes, you can import them from the Keil pack installer.

Hope this helps !
