Given a choice, you should use peripherals that are listed as supported by Neutrino. This includes such items as disk controllers, network cards, PC-Card controllers, flash memory chips, and graphics controllers. For lists of supported hardware, see the Community area of our website, http:www.qnx.com; for information about third-party products, see the Download area.
Graphics controllers are one of the particularly delicate areas in the design of an embedded system, often because a chip may be very new when it's selected and we may not yet have a driver for it. Also, if you're using a graphics controller in conjunction with an LCD panel, beware that this is perhaps the most complicated setup because of the many registers that must be programmed to make it work.
