hiya folks!
I'm just now getting back to some project ideas I developed a while back, particularly with the PSP LCD and touchscreen modules from SparkFun. I had followed (loosely) the development of the controller/FPGA board SparkFun had been working on, but lost track of things as I got pulled away into other school work.. thus I have been catching up on all the PSP/LCD conversations as of late, attempting to synchronize these bits of information with the design parameters I am setting.
From all of this, I've got some questions I'm hoping you wonderful folks can help me with, though I'll cover the basic aspects of the design first:
. I'm putting this together for my undergrad CE senior project, and working under semi-flexible conditions.
. The main idea is to build a touchscreen system, where objects on the screen are created/manipulated using the touchscreen overlay for the LCD.
. As this is CE, I'm fine working with both the hardware and software aspects of the system, though given my time constraints (~8wks), I'd like to keep the hardware as simple as possible. (though using something like the virtual cogs' LCD setup doesn't seem to be an option, too complete).
. Given this, I'm imagining using a fairly powerful 32bit dev board for the main control (I have an Atmel ATEVK1100 available if I choose)
. My main problem is in figuring out a controller setup for the LCD (not worrying about touchscreen stuff just yet)
. Aside from time, my other constraint is manufacturing, I don't have the tools (nor time) for PCB layout/etching, specialized chip packages, etc.. so hand-soldering and sockets are my thing
----
In all the research I've done, there certainly are a number of options/paths to choose from. I've seen suggestions for the standalone Epson LCD controllers, the AT91SAM9261 uC, various FPGAs, etc.
Herein lies my difficulty..
----
My Questions:
. does a microcontroller board such as the EVK1100 have enough power to drive the LCD and everything else?
. Should I really be going with an LCD controller such as something from epson? (in addition to a microcontroller for system control) http://www.mouser.com/search/refine.aspx?Ntt=S1D13742
. are the FPGA setups (such as the work SparkFun originally did), something analogous to the epson controllers? If so, would this then need a uC or something similar to send the display data?
. Someone suggested the picaso board for a different LCD, I'm assuming this can't be used with the PSP LCD (the board seems to speak VGA/SVGA), correct? http://www.sparkfun.com/commerce/produc ... ts_id=8541#
. Are the Epson controllers capable of being hand soldered, or should each of those packages be used in a PCB layout? Would it be possible to use a socket instead?
. has anyone successfully located connectors for the PSP LCD's backlight and touchscreen?
Thanks for your help!
