Abstraction Layer API¶
The MicroVG implementation for MicroEJ requires an Abstraction Layer implementation. The Abstraction Layer implementation consists of a set of header files to implement in C to target the hardware drivers.
The VG Pack’s embedded Front Panel extension implements all MicroVG features for the simulator.
Embedded VEE Port¶
The specification of header files names is:
- Name starts with
- Second part’s name refers to the VG engine:
- All file’s name ends with
_impl: all functions must be implemented over hardware or in software.
A master header file initializes the native Vector Graphics engine: see LLVG: VectorGraphics. All other header files and their aims are described in next VG engines chapters: Matrix, Path, Gradient, Image and Font.
