HAL library 12- LCD for STM32Fxxx

LCD is first big library provided from me. It’s the same as SDRAM, it works on STM32F429-Discovery, STM32F439-EVAL and STM32F7-Discovery boards. With one library you can control 3 boards just by selecting proper define in your target. Library can be extended to other boards. Library requires FMC peripheral for SDRAM for display memory, DMA2D for fastest graphic accelerations and LTDC for transferring layers to LCD.

Library 62- Fast Fourier Transform (FFT) for STM32F4xx

Here 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 50- STemWin for STM32F429-Discovery

ST provides emWin library from Segger. It is professional GUI (Graphical User Interface), optimized for speed and performance for microcontrollers. ST has it’s own implementation, called STemWin. With this GUI, you can do many thing, of use simple buttons, dialogs, text boxes, to playing videos, displaying pictures, menus, etc. I suggest you that you go to segger’s website and read more about this very useful tool. In my library, I’ve some changes from original ST’s example for STM32F429-Discovery board, because...

Library 18- ILI9341 with LTDC on STM32F429 Discovery

It’s been a while when I first got ILI9341 lcd working on discovery, but without LTDC driver. Yesterday I decided to make a new library. With LTDC, you can actually display movies, because it uses parallel communication and support 2 layers simultaneously what gives you a high refresh rate. I used my old ILI9341 library and just add/modify some things to get LTDC to work. LTDC also supports 2 layers, so this means that while one layer is displayed, other layer...
