I have installed nrfConnectSDK and Segger Embedded Studio.I am able to build the example codes like blinky.But where do i write my custom application code?Is there any main.c file where i can write my custom code?https://devzone.nordicsemi.com/f/nordic-q-a/70524/i-have-installed-nrfconnectsdk-and-segger-embedded-studio-i-am-able-to-build-the-example-codes-like-blinky-but-where-do-i-write-my-custom-application-code-is-there-any-main-c-file-where-i-can-write-my-custom-codeI can only see the conf files and other yaml files when i open nrfconnectsdk sample in Segger embedded studio IDE.Where do we exactly write our application code?Application code might be running a motor based on BLE command from a central device.en-USTelligent Community 13Sun, 17 Jan 2021 18:13:29 GMTRE: I have installed nrfConnectSDK and Segger Embedded Studio.I am able to build the example codes like blinky.But where do i write my custom application code?Is there any main.c file where i can write my custom code?https://devzone.nordicsemi.com/thread/289581?ContentTypeID=1Sun, 17 Jan 2021 18:13:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f399eba3-9547-42a1-a94a-33c9d6927233J&#248;rgen Holmefjord<p>Hi,</p> <p>The main.c file is normally located in the src directory in the samples. In SES, you should find the main.c source files under Project &#39;app/libapp.a&#39;:</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/ses_5F00_main_5F00_source.png" /></p> <p>I would highly recommend you to have a look at the <a href="https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/">nRF Connect SDK tutorials</a>.
