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

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. đŸ™‚ Libraries are tested on my 4 STM32F4...

Library 11- Button library for ILI9341 LCD and STMPE811 touch controller on STM32F429 Discovery board

Now we have both, LCD controller and touch controller configured and we can use this. For this purpose i made a library for buttons. This library can draw buttons on LCD and check if touch has been pressed on any enabled button. Library Features Set X and Y location of button Set button’s width and height By default 10 buttons are supported Use labels Custom background image or color Border around button Selectable font Disable/Enable button Selectable color for label,...

Library 10- STMPE811 Touch screen driver for STM32F429 Discovery board

STM32F429 Discovery board has LCD with ILI9341 controller and resistive touch screen with STMPE811 controller from STMicroelectonics. The STMPE811 is a 4-wire resistive touch screen controller with a GPIO (general purpose input/output) port expander able to interface a microcontroller or a main digital ASIC via I2C or SPI serial interface. The STMPE811 offers great flexibility, as each I/O can be configured as input, output or specific functions. The touch screen controller is enhanced with a movement tracking algorithm to avoid excessive...
