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
Major Changes
- The configuration option GFX_COMPAT_V2 is now defined that allows most V2.x code to compile unchanged. It is turned on by default.
- The single-file-make build mechanism now works with all uGFX features.
- Many types and constants have been renamed to prevent conflicts with other library, operating systems or other code.
- The GDISP API has been significantly changed.
- Multiple display support now works very differently.
- All drivers are now included using configuration options rather than by linking.
- All uGFX drivers now use a new internal API and have been rewritten.
- Many hardware interface details that needed to be written explicitly into every driver board file are now handled by a new GBUS module.
- There are new triginomic functions that are significantly faster and more accurate than the old functions in GMISC.
