This is a P2X8C4M64P/Propeller 2 QVGA display engine.
IMPORTANT: This software is meant to be used with the p2-spin-standard-library (P2X8C4M64P). Please install the library first before attempting to use this code, otherwise you will be missing several files required to build the project.
- QVGA 320x240 resolution (signalled as 640x480, with pixel-doubling), 8bpp color
- Integration with generic bitmap graphics library
- Double-buffering (optional)
- Wait for vsync, or current vsync status (function calls)
- Display intensity
- Includes simple video timing adjustment utility
P2/SPIN2:
- p2-spin-standard-library
- 1 extra core/cog for the PASM engine
- 76.8kBytes RAM for single-buffered display, or 153.6kBytes for double-buffered
- graphics.common.spin2h (provided by p2-spin-standard-library)
