Hi,

You can refer to this post to use the Embedded Studio IDE.

Go to https://license.segger.com/Nordic.cgi to register your license.

Fill in the form. (The MAC field is the MAC address of the network card on your computer, also known as "physical address". Usually, you can find that through control panel or similar. Find the settings for the network card and "view details" or similar.)

Follow the instructions. (You will receive an email from Segger with an activation key, that you enter in the License Manager within Segger Embedded Studio.)

Hello,

thanks.

Could you give me a single IDE very simple to use to progress in assembling your processor in the microbit card.
I simply want to start with a simple assembler file, then create the object file and then create the executable with the linker.
Thank you for giving me a single IDE with the method to do all these steps and finally run the executable file in the Microbit card.

I know how to do on the raspberrypi, but would have the method on the microbit with a hypersimple example like displaying the result of an addition between 2 numbers for example. You have very good engineers, I am sure they have the answer very quickly, because this request is very basic.

Your sincerely.

Julien

Hi Julien,

[quote user=""]Could you tell me if this processor is based on a Von Neumann type architecture?[/quote]

The processor inside of Nordic nRF51822-QFAA-R is ARM Cortex-M0 CPU which is Neumann type architecture.

[quote user=""]Would you have a very simple IDE to advise me.[/quote]

This post might help you.

[quote user=""]Could you confirm that the computer world no longer uses the assembly language, because the high-level language complier is good enough and optimizes the code.[/quote]

Though it's true, you probably won't find yourself writing your next customer's app in assembly, there is still much to gain from learning assembly.
Today, assembly language is used primarily for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues. Typical uses are device drivers, low-level embedded systems, and real-time systems.
Assembly language is as close to the processor as you can get as a programmer so a well designed algorithm is blazing -- assembly is great for speed optimization. It's all about performance and efficiency. Assembly language gives you complete control over the system's resources. Much like an assembly line, you write code to push single values into registers, deal with memory addresses directly to retrieve values or pointers. (source: codeproject.com)
