The PIC On Screen Display (OSD) project board available from
The project board combines the 16F628 with the STV5730A OSD chip used to generate the on screen menus for VCRs. Fully compatible with both PAL & NTSC video standards the project board will overlay text and graphics characters onto the composite video signal from any camera or other video source. It can also generate its own video signal which can be displayed on any TV, video monitor or VCR with a composite video input.
A set of on screen display routines and advanced example programs is also available to aid the development of more complex screen displays.
Cut out the tedium of project development and get straight to the fun of making your idea work with proven hardware and well commented easy to understand example code.
