how to use FFT on stm32f4xx series mcu?

I want to use FFT functionality on stm32f4xx mcu, so where can I find some guide document about this? Thanks!

Create array of random number without CPU intervention for blocked processing.

I know we can have time interrupt, each time it copy from RNG to array elemnts and control its address by a counter variable to inrement destination address until end of array reaches and it resting the counter and repeat the process. But is there an...

will B-L475E-IOT01A board supports FFT commands like converting time dominie to frequency dominie.

I am trying to convert time dominie to frequency dominie to calculate FFT of that data. If so, who can I do that.

Which stm32 MCU can do fastest DSP, arithmetic & floating point calculation?

I want to make robotic arm , CNC controller for this purpose which STM32 is capable to do DSP, arithmetic and floating point calculation Faster (less clock cycle for execution)without much execution code delay?So interpolation and trigonometric fu...

Project for STM32F746 disco with the protocol 61850 Ethernet communication, work with DSP library, working in real-time.

I am trying to make a frequency relay with the STM32F7 disco, for a simulated power electrical systems in real time (OPAL RT); I need to establish a communication between the real time simulator and the STM32F746 dico, through one of the protocols it...

I am interested in STM32U5 because of CORDIC as I do have trigonometrically intense applications. Apparently DSP with hardware multiply is superior, and is also provided in the STM32U5. Respectfully, why include CORDIC when DSP is also available?

How to apply compiler option like "attribute((section(".ram")))" to math.h functions ? Where are actually these functions ?

Resolved! How to use DSP in STM32G070?

I have used DSP in STM32F411 successfully,but when i want to use DSP in STM32G070 , i find the DSP files are some different,such as G070's DSP files : ./Sourse/. have a Cmakelists.txt. i dont know how to use that txt file, so i just add DSP as usual...

How to use arm_rfft_q15 properly.

I created a 10Hz sine function with phase of pi/4, amplitude of 1000, bias of 2000, a sampling rate of 1kHz, and 2048 samples (20 periods in total) and saved it into q15_t input[2048].I created a fft stract by arm_rfft_init_q15(&S, 2048, 0, 0)I enter...

Hi, I am currently trying to understand the FMAC and I have some questions

I found AN5305 and the presentation on the ST website but it doesn't fully answer my questions:How long does it take to calculate a result? Is it one clock cycle for each multiplication and addition?Is it possible to configure the FMAC so that it can...
