A project log for NTSC/PAL Video Display Shield

An Arduino NTSC/PAL video display shield with integrated framebuffer and composite video output.

To use the Video Display Shield with an Arduino Mega or Due, a cable to connect the SPI port to the shield is required. The cable would interfere with the shield, so I had to use an extra set of Arduino headers to raise the shield and open up some room underneath. Here demonstrated with a Mega board.

To make the system more compact, I literally hacked the shield (with a Dremel) to provide an open slot to feed the cable through without interference. 

And a closeup for the details.

Another option would be to use a soft core (bitbang) SPI and assign the standard Uno SPI pins. This depends on the application.
