You can NOT safely assume that color devices use a specific SED chip. New devices are constantly coming to market, from Palm, Sony, and others. The rule should always be that you first check out what you're running on, and only if you KNOW you've got a specific kind of hardware do you start poking around with it. Otherwise, you fall back to a slower but safe solution that uses the existing Palm OS APIs.
When a new device comes along, you may have to update your app in order to get your app to take advantage of it's graphics hardware. Better that than the alternative: your app assumes the new device has some hardware that it in fact doesn't have, so it crashes. The question then becomes how to test various aspects of the hardware. This has been discussed on the forum before, and the answers aren't always as good as I think they could be. The Astraware folks gave an excellent presentation at the last PalmSource conference in San Jose that covered this topic. -- Peter Epstein -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
