There are many major changes from uGFX V2.x to V3.0. While we have tried to maintain compatibility for most uGFX V2 applications there are some areas that will require re-writing.
Contents
Compatibility
The configuration option GFX_COMPAT_V2 is now defined that allows most V2.x code to compile unchanged. It is turned on by default.
Single-File-Make
The single-file-make build mechanism now works with all uGFX features.
Type and Constant Changes
Many types and constants have been renamed to prevent conflicts with other library, operating systems or other code.
The New GDISP API
The GDISP API has been significantly changed.
Multiple Display Support
Multiple display support now works very differently.
Adding Drivers To Your Build
All drivers are now included using configuration options rather than by linking.
New Driver Format
All uGFX drivers now use a new internal API and have been rewritten.
The New GBUS Module
Many hardware interface details that needed to be written explicitly into every driver board file are now handled by a new GBUS module.
New Trig Functions
There are new triginomic functions that are significantly faster and more accurate than the old functions in GMISC.
