@ -51,6 +51,15 @@ FEATURE: Added gwinTextEditSendKey() and gwinTextEditSendSpecialKey()
FEATURE: Implemented the JPG image decoder
FEATURE: Added SSD1322 driver
FEATURE: Added support for Zephyr operating system
FEATURE: STM32LTDC driver now supports using both layers as seperate displays. The 2nd display is the foreground layer
CHANGE: STM32LTDC driver now uses RGB888 pixel format by default
FEATURE: Added GDISP_LTDC_USE_RGB565 config variable to force STM32LTDC driver to use RGB565 pixel format
FEATURE: The STM32LTDC 2nd display (the foreground layer) supports alpha.
FEATURE: The STM32 board files for known boards have been updated to contain support for the 2nd layer.
FEATURE: Added AHTML2COLOR() and ARGB2COLOR() to support alpha. This is currently only supported for the RGB888 pixel format.
FEATURE: Added the new color GFXTRANSPARENT - only available for RGB888 pixel format on alpha capable displays.
NOTE: Alpha support in RGB888 requies an alpha capable display (STM32LTDC 2nd display only currently)
NOTE: Alpha support in RGB888 is NOT the standard ARGB8888 format. Only use AHTML2COLOR() and ARGB2COLOR() to create alpha colors.
*** Release 2.7 ***
