[PavanSgowda]

Dear Sir/Madam,

I'am new to segger embedded studio.I would like to do SPI interfacing of an IC using nRF51822 with segger embedded studio.

Please guide me how to add the necessary driver files into my project.

Hi,

If you do not already have the SES project for nRF51 up and running, there is a tutorial on how to convert a Keil project available here.

Regarding usage of SES with our SDK, please have a look the this video tutorial playlist on YouTube.

Best regards,
Jørgen

Hi,

There is a SPI Master Example in the SDK that you can reference. The SPI master driver is found in "nRF5_SDK_12.3.0_d7731ad\components\drivers_nrf\spi_master", use the nrf_drv_spi.c/h version.

Best regards,
Jørgen

You should follow the tutorial closely, the nrf.h file is located in the components/device directory:

• Select Project -> Edit Options... and then select the Preprocessor tab
• Add ../../../../../../components/device to the User Include Directories field to include the device header files in our Embedded Studio project

Your user include directories should look like this now:

I also see that you have added system_nrf52.c and ses_startup_nrf52.s, these will not work for nRF51 chips. You may find some useful information in this post.

Dear Sir,

I had followed almost all steps to import a keil project into segger embedded studio.

Unable to perform few of them mentioned below.

1) Add SDK to "flash_placement.xml", "ses_nrf51_startup.s" and "thumb_crt0.s" to "/components/toolchain/embedded_studio" folder.

issue-Unable to find "flash_placement.xml" and  "thumb_crt0.s" files in the SDK.( suggested in this link -You may find some useful information in this post.)

Currently I'am using segger embedded studio v5.2,is it compatible to develop a application of nRF51822??.

Currently I'am facing an error in the process of importing a keil project into Segger Embedded studio.

Please look at the image below to see the error generated.

I think you should try with an older version of SES. It seems like the import is not handling paths and settings correctly. I would recommend with the version mentioned in the tutorial (3.10e), as this is the version that would likely cause the least amount of issues. I cant find this version for download from Seggers webpage, but they may be able to provide it if you contact them. After you have the project working correctly, you can switch to a more recent version of SES.

Hi,

Whom should I contact to get the older version of SES?

Hi,

I spoke to segger people,and their response is copied below.

Hello Pavankumar S,

Thank you for your inquiry.

This is quite a weird suggestion by Nordic. So instead of guiding you through the process on how to fix their software and thus the error they suggest you to use an IDE version that is now more than 4 years old...

A general guide on how to import projects from other toolchains to Embedded Studio is explained here:

https://wiki.segger.com/Port_Projects_from_IAR_Embedded_Workbench_to_Embedded_Studio

It is a guide for IAR but the process is the same for Keil.

If you still run into issues with the Nordic SDK software, we recommend to work with Nordic support to help you fix the remaining errors.

If you insist we can of course provide you with SES 3.10e, however we are quite sure this will not help and be rather counter productive as a 4 year old version of Embedded Studio will behave completely different than today's version and have tons of bugs that have been fixed in the last 4 years.

So again, we really recommend to make the Nordic software work with the latest Embedded Studio version with the help of Nordic support/community forum.
