• RFFT CMSIS-DSP - Fluctuating index
    I am using the Cortex M4 with CMSIS 5.4.0 DSP library. I'm using the arm_rfft_f32() function and the max_arm_f32() function to compute the maximum frequency bin of injected pure sine wave with an external...
  • CMSIS-DSP on ARMv8-m
    Hi, I'm reading through the sources of CMSIS-DSP and came across the following question: The define of "ARM_MATH_DSP" is only set if the target architecture is "ARM_ARCH_7EM". Does this mean, that all...
  • How to prepare ADC data for Q31_t CMSIS DSP functions?
    Hi to you all, I've another post on the forum (here's the link Process ADC data, moved by DMA, using CMSIS DSP: what's the right way? ), but since I think I made some small steps forward I felt I could...
  • Cortex M4 and ARM FIR Q15 Hardfault
    Hi I have tried to test CMSIS DSP FIR library in my STM32G474. Unfortunately after writing a simple test code, where i have prepared input signal and fir coefficients (by Matlab, verified) processor...
  • How to determine CMSIS version?
    I have a project with CMSIS already integrated - I would like to find which version of CMSIS - how do I do that? I thought perhaps the file: https://github.com/ARM-software/CMSIS_5/blob/develop/CMSIS...
