It is also very important to make sure in whatever you’re doing the clock source is as clean as possible. These clock rates are pretty high, they’re in the several MHz to tens of MHz depending on your application. A clean clock can make a huge difference in the success and the stability of an application from a system viewpoint. Finally, when you hook the Blackfin to an LCD panel as a 666 LCD, 6-bits of R, G and B for a total of 18-bits, the Blackfin connects as a RGB565 device. When you do this, do not ground the least significant bit of the red and the blue channel. This is a common practice that is not ideal in terms of the dynamic range that you’re representing.
