Re: Best approach, LCD on ARM7

For a new project, we have almost decided on AT91SAM7X256 for a variety of
reasons. Primarily due to its rich peripheral set and previuos knowledge of
Atmel Chips.

But we need to implement a LCD display, preferably 320x240 pixels into our
system and we would like some advice on the best way to do this. With
respect to both hardware and software development. I.e how to get a grip on
this. would we use LCD controller or do direct IO from the processor?

We're using the LCD library from Simplify Technologies
http://www.simplify-technologies.de/gui_library/index.html
which has been great - it's not (or wasn't!) licensed on a 'per
product' basis which makes it cheaper if you want to use it in multiple
projects.

I'm interested to know what people suggest for the HW side of things -
we're looking at adding a LCD to a Atmel SAM7 chip without an external
address bus and, so far, haven't come up with any good ideas. There
don't seem to be any 320x240 SPI based controllers around - one
suggestion was to put it in a FPGA and write some logic to convert
between SPI & an "address bus" based FGPGA video controller.
