I try to use "arm_math.h", but I can't find any function about logarithmic operation in "arm_math.h". Is there none logarithmic in this, or am I not found?
I am starting a DSP class project that will be auto-adjusting blinds using the Nucleo-L476RG board. To start off, I am wondering how it is possible to control the Nucleo board wirelessly with an android phone. I am aiming to control a stepper motor ...
If yes some example for fft from ADC data . Howto max speed convert ADC array into fft input in CCMRAM , what is better f32 or q15?
I measured the time took to run a length 127 Multiply–accumulate routine by togging a GPIO pin before and after the arm_dot_prod_q15() routine. And then I can measure pulse width by a scope. It was 7us on the STM32F413 and 6us on the STM32H7A3.
Hi all,I am working with CMSIS DSP alghoritms and currently I get stuck with FIR and iir filtersWhen data are predefined in float32_t arrays everything works fine like bellow for FIR lpfBut when i am trying to use the same filter for array from ADC i...
Hi, Expert,I have STM32F407-Discovery and I'd like to use CMSIS DSP Library for audio processing.When I checked the library version which is released, it looks 5.5.4.So, I downloaded latest CMSIS DSP Library and build it for cortex-m4 atchitecture,Be...
Hi, We are using DSP device STM32F107VCH6 and would like to know how many heat cycles the chip can withstand before its operation is compromised, by heat cycles we mean surface mount reflow cycles and any subsequent removal for rework / component sal...
The following document explains the DSP library for STM32F10x which contains the functions for the PID controller, is it compatible with STM32G474RE? If not, would you please guide me about its implementation on a microcontroller? https://community.s...
