Can CMSIS-DSP support complex FFTs longer than 4096 samples on Cortex-M ? The quick answer is yes with some changes. The limitations and problems are coming from the "bit reversal" phase : the ...

This project demonstrates the use of ADC (Analog-to-Digital Converter) for real-time voltage readings on an STM32 microcontroller, the CMSIS/DSP math libraries for FFT (Fast Fourier Transform), and ...

Abstract: The swift advancement in microprocessor and digital signal processing technologies has led to the employment of advanced digital tools and evaluators to process and scrutinize the layered ...

Some may ask why you’d want to program a Cortex-M microcontroller like the STM32 series using nothing but the ARM toolchain and the ST Microelectronics-provided datasheet and reference manual. If your ...
