how to use CMSIS-DSP library on nrf51822

[vernon]

Hello,

Is it possible to run CMSIS-DSP library on nrf51822, I would like to use the FFT function for analysing the accelerometer raw data on nrf51822. Is anyone have already run it on nrf51822 that without FPU.

Thank you.

It is possible to use the CMSIS libraries directly. Just download them and include them in your project. The nrf51 is using a ARM M0 core, and there are some DSP libraries supported by it at the link.

no that blog post has nothing at all to do with CMSIS-DSP, that's just about the deprecation of CMSIS Pack which was a way of distributing things for installation into Keil. There was confusion on that point at the time, seems there still is.

Indeed just downloading the CMSIS-DSP libraries for M0 is all you need to do, link with them, job done.

Thanks for clearing up the confusion about the CMSIS pack, I have removed it from my answer to avoid propagating any further confusion. For those interested, the old Question and Blog Post that caused the confusion n the first place.
