EasyGUI preview on STM32F7-Discovery

Last 2 months I was working hard to build a platform independent graphical user interface library for embedded systems. I called it EasyGUI because idea behind is very simple library with support for custom user based widgets with touch and keyboard support. So far I built these features: Unlimited widgets (limited to RAM memory) Support for widgets which support children widgets (windows, panels, etc) Support for touch and keyboard events Support for UTF-8 encode and decode functions Support for custom...

HAL Library 23- TOUCH for STM32Fxxx 6

HAL Library 23- TOUCH for STM32Fxxx

The TOUCH library is a “high” level library for touch operations. It requires low-level drivers for communication with your sensor/device, but for high level for user, always the same functions are used. This allows you flexibility between multiple low-level device drivers to be used with in your project if needed and also allows single lib to have the same features for all projects. Library Read more about new HAL libraries Features Custom selectable driver Built-in drivers for STM32F429-EVAL and STM32F7-Discovery...

All STM32 HAL libraries

In this section, I will write all libraries based on HAL drivers from ST. If you see this first time, make sure you read this post first about how structure of my libs looks like!

New STM32F7-Discovery board

After STM32F411-Nucleo, STM32F439-Eval board, ST sends me a new discovery board, STM32F7-Discovery. This is a very powerful discovery board according to other series. It is also very big with a lot of features. The STM32F7 discovery kit allows users to develop and share applications with the STM32F7 Series microcontollers based on ARM® Cortex®-M7 core. The discovery kit enables a wide diversity of applications taking benefit from audio, multi-sensor support, graphics, security, video and high-speed connectivity features. The Arduino connectivity support...

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...
