New nRF Project Creation using nRF Connect SDK

[mexco]

I am new to Nordic. I installed nRF Desptop Connector. I have opened succesfully the sample nRF projects. Now, I want create my own new nRF Connect Project. I tried two ways:

1. First created a new folder named "First" in "C:\nrc\v1.7.1". I tried to create a new project using nRF Connect Options in this folder. But there is option to open either existing nRF project only. see first image ... 

2. I creted a new project in SES without nRF Connect SDK in the above folder. The default "Hello World" code builds successfully.see images 2 and 3. But, I want to know how to open/ convert this new project as nRF Project, see image 4.

Hi Gulzar

If you are new to developing with Nordic, I advise you to use the nRF Connect Extension for VS Code.
This has a nice collection of videos to get you started, as well as a more in-depth webinar if you want to learn more on it.

In addition, to learn more on the basics of nRF Connect SDK, I recommend this tutorial.

To answer your question:

A project in nRF Connect SDK is a folder with at minimum the following parts:

CMakeLists.txt
prj.conf
a src folder with .c file(s) inside

Here is an example of a minimal application

The CMakeLists.txt will point to your C files, for example like this:
"target_sources(app PRIVATE src/main.c)"

When you choose "project", Segger Embedded Studio will only look for a folder containing the mentioned files.
To create a new project, you need to find an example, then copy it manually.
Then you can chose this new folder as if it were an existing project.

Dear Hellesvik.. thanks for your vakued suopport and guidance. In continuation before closing this ticket, may you guide lilte more:  I want to test a simple program on the nRF5340_DK kit in which an normal LCD16X2 is to be interfaced.

1. How to define the Port Pins e.g.: in some generic compilers the port pins and port can be defined as below 

#define RS P0.4

#define EN P0.5

#define lcd_port P0

//******

But, how to define 1 bit, 4 bit, 8 bit interface in SES with/ without Zephyre. May you show a small function  to:

1. Define the Individual Port Pins

2. Define 8 bit Port

3. Sent data to 8 bit Port

4. Set Pin and Clear Pin

2. To write a program to interface Button, Leds and LCD, which Zephyr files are required to include at Minimum in the project.

Hi

Some points here:

The nRF Connect SDK is buildt on Zepjhyr, so you will be using Zephyr either way.

The nRF5340 is a 32 bit microcontroller, so registers will be 32 bits, not 8 bit.

To toggle LEDs, I would recommend using the GPIO API in Zephyr, see the Blinky sample.
