Too many tile drivers !

william chan

There are so many tile drivers in the OBEX.
Some use one cog, some use 2 cogs and some use 3 cogs.
I am getting confused about which tile driver I should use.

Can somebody do a comparison table for all available tile, text and graphics drivers so a newbie like me can make an select the most suitable one.

The only comparision that I know of similar to what you are asking for is here: http://propeller.wikispaces.com/graphics+drivers It has not been updated in a while, and does not include very many OBEX entries (if any).

In the tile drivers there are several factors:

Output (VGA, NTSC only, NTSC/PAL)
Display Dimensions (fixed on some, adjustable on others)
Bits per Plane (BPP)
Tile Size (8x8 pixels, 16x16 pixels, etc.)
Number of Cogs (used for rendering)

Most of the drivers in the OBEX have this information documented. As far as saying which is "best," it is subjective.

If you are looking for basic text output then the TV_Text or VGA_Text objects from the OBEX (or in the Propeller Tool) are certianly good starting points.

If you are looking to get more text on the screen, and do not mind using NTSC/PAL output, then the 40x30 NTSC TV_TEXT using half height ROM FONT is a good choice.

Hopefully that helps.
