CMSIS NN

[arditdv]

Dear nordic team,

I'm developing a sensor based on nrf52840 and I want to make use of CMSIS NN. I have already integrated CMSIS in my eclipse project and can already use the dsp library.

If I try to link the NN headers the following errors are displayed during compilation of the project. If you have a solution or a suggestion, I would really appreciate it.

Best regards

Hello,

We don't support Eclipse. If you are looking for a free to use IDE, I suggest you take a look at Segger Embedded Studio (SES), which has a full version for free when you are developing on Nordic Products. 

For CMSIS in SES, please see this guide:

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/sdk_config.html?resultof=%22%43%4d%53%49%73%22%20%22%63%6d%73%69%22%20

NB: We are really short staffed due to Summer Holidays in Norway. You must expect some extra delay in technical questions these days, I am afraid. I am sorry for the inconvenience.
