Single LCD library for different boards 39

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 51- Chrom-ART Accelerator (DMA2D) graphic library on STM32F429-Discovery 11

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...

STemWin on STM32F429-Discovery board 77

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...

All STM32F4 libraries 123

All STM32F4 libraries

Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...
