Library 62- Fast Fourier Transform (FFT) for STM32F4xx

HereĀ is an example of Fast Fourier Transform on STM32F4xx devices. Today, I was looking something on ARM DSP documentation and I saw that some functions for FFT used in my example are deprecated and will be removed in future. That was the main reason I decided to make a library for FFT on STM32F4xx. To use this library, some third-party libraries are also required. All these required files can be found in STM32F4xx Standard peripheral drivers and DSP instructions provided...

Library 51- Chrom-ART Accelerator (DMA2D) graphic library on STM32F429-Discovery

ST’s Chrom-ARTTM Accelerator function or DMA2D is supported in this library. This is powerful tool in STM32F429/39 or STM32F427/29 devices. It is based on DMA transmission from graphic to memory in top possible speed. This can be used to draw moving objects, rectangles, circles very fast without a lot of work. My DMA2D GRAPHIC library was designed in a way that can support any LCD. Because anything that DMA2D knows is writing “data” (color) in memory at some locations. You...
