Hi guys with Raymans help well all his help I have a 128X64 display connected to my prop board it has a parallel interface very similar to the 4X20 LCD display from Parallax..
My question is this it works fine but I would like to take Composite input to the prop board and have it output to the graphics boards its only black and white by the way is there someway to do this without major programing?
I hope I am explaining it properly ,, so the LCD is working just fine with the prop board but instead of taking an NTSC output from the prop can I use that circuit as an NTSC input and then have the video displayed on the parallel LCD device??
I have always wondered if the prop board could read video as an input as well as outputting video
Thank you

Hanno has a PropCV module for ViewPort that works with an external parallel A/D converter, that could be used to get a gray scale image, which you could convert to dithered B&W to display.
Look up Floyd-Steinberg (spelling?) dithering of grayscale to b&w...
