  • Significantly decrease the stack usage required for word-wrapping
  • Added justifyTop, justifyMiddle & justifyBottom text justification to GDISP
  • Added justifyWordWrap, justifyNoWordWrap text justification to GDISP (requires GDISP_NEED_TEXT_WORDWRAP)
  • Added justifyPad, justifyNoPad text justification to GDISP
  • Added GDISP_NEED_TEXT_BOXPADLR and GDISP_NEED_TEXT_BOXPADTB configuration options
  • Fixed an issue on FreeRTOS where thread stacks were being created too large
  • Added UC1601s driver
  • Fixed issues with the STM746-Discovery board with ChibiOS
  • Added partial definition for the STM32F469i-Discovery board
  • Fixed issue where the variable type of the syncflags of the STM32LTDC driver was too small
  • Added KS0108 driver
  • Added RA6963 driver
  • Fixed clipping issue in gdispGDrawString()
  • Upgrade GFILE FATFS support from V0.10b to V0.13
  • Added UC1610 driver
  • Fixed to allow gwinSetText with static text on a TextEdit control
  • Fixed to ChibiOS realloc on a TextEdit control
  • Added support for CMSIS V2.0 operating systems (eg RTX5)
  • Removed long deprecated functions gfxSemCounter() and gfxSemCounterI()
  • gwinDetachToggle() is now a visible part of the API
  • Update OSX makefiles (allows for 64bit building)
  • Fixed resetting a timer on gwinImage objects when using animated GIFs
  • Added gwinTextEditSendKey() and gwinTextEditSendSpecialKey()
  • Implemented the JPG image decoder
  • Added SSD1322 driver
  • Added support for Zephyr operating system
  • STM32LTDC driver now supports using both layers as seperate displays. The 2nd display is the foreground layer
  • STM32LTDC driver now uses RGB888 pixel format by default
  • Added GDISP_LTDC_USE_RGB565 config variable to force STM32LTDC driver to use RGB565 pixel format
  • The STM32LTDC 2nd display (the foreground layer) supports alpha.
  • The STM32 board files for known boards have been updated to contain support for the 2nd layer.
  • Added AHTML2COLOR() and ARGB2COLOR() to support alpha. This is currently only supported for the RGB888 pixel format.
  • Added the new color GFXTRANSPARENT - only available for RGB888 pixel format on alpha capable displays.
  • Alpha support in RGB888 requies an alpha capable display (STM32LTDC 2nd display only currently)
  • Alpha support in RGB888 is NOT the standard ARGB8888 format. Only use AHTML2COLOR() and ARGB2COLOR() to create alpha colors.
  • Added nullpointer checks to GDISP image functions (with new error code GDISP_IMAGE_ERR_NULLPOINTER)
  • Add cache flushing to the ChibiOS FATFS/PETITFS block drivers. Needed for STM32F7 chips. This should really be in the ChibiOS DMA routines.
  • Add cache flushing to enable DMA2D accelerated bitblits in the STM32LTDC driver on the STM32F7 CPU
  • Improved STM32F469i-Discovery board support
  • Improved STM32F746G-Discovery board support

Right now I'm trying to understand and evaluate the software. Thanks to all those who are developing and making available to the community for free.

This library is state-of-the-art software provinding an easy and fast way to integrate graphic displays to your project. It also provides additional drivers for touchscreens devices. Audio input/output modules are included too. Support is great, through community forum and IRC channel. It's free to use for home and hobby applications and commercial licenses have a great price. uGFX supports the more popular boards, display drivers and operational systems or just bare metal applications. I would recommend this to anyone who needs a high modular and lightweight solution.
