DSP on nrf52832

[silvergaucho]

Hey guys,

how can we use DSP math functions on the nRF52832 little monster? Is there somewhere some documentation?

What about power consumption and performance?

Thanks.

It's an ARM Cortex-M4F CPU - so you use the DSP functions in exactly the same way you'd use them on any other Cortex-M4F.

Thank you awneil, much appreciated. I'm working on a different environment than keil (Visual Studio + VisualGDB), I will have to download the CMSIS library and use it in my environment? Do you have some information about power and performance? I'm completely new to DSP.

I'm also attempting to use the "arm_math.h" library for the nRF52832 (SDK v11.0.0). The CMSIS library is included in my project (using Eclipse Neon1.a): submodules/components/toolchain/CMSIS/include/arm_math.h. However, my linker can't resolve the symbols....So I manually downloaded the static library and added to my path and my linker still can't resolve the problem. Is there any secret that I'm missing?

Static Library: "libarm_cortexM4l_math.a"
