Hi,

I bought this TFT screen that id like to use in a project. When I bought it I was under the impression that it would be easy to interface it to a standard VGA source, but this seems not to be the case. The controller for the screen takes an 8 bit parallel input.

Is it possible to interface this type of screen with say, a Raspberry Pi or even my computer, to act as a monitor? Are there any chips you know of that takes HDMI/DVI/VGA and converts it to the parallel RGB type the controller takes? I found a dev board from the same company that can display composite video, but I haven't found anything for VGA.


Thank you
 

Hi,

Are you looking for this type of chip... Like AD9882 which will give VGA output means RGB data out with Hsyc, Vsync and Blank_EN etc...

http://www.datasheetcatalog.org/datasheet/analogdevices/AD9882_PCB.pdf

If you cant find the solution, can you please describe more about your need... ?

means what is the scenario that you are facing...?

Because the display pannel should need the HSYNC, VSYNC, BLANK_EN pulses with the RGB data (8 bit, 16 bit, 24 bit format....)
 

Hi,

I think you need a CPLD and DVI receiver to covert HDMI/DVI to the 8-bit parallel video data. For low resolution DVI/HDMI interface, spartan6 FPGA could be a single chip solution.:cool:
