Hacking An Old Parallel Port Webcam To Work With A Gameduino 2

connecting parallel port web camera to gameduino 2

[Andrew] couldn’t pass up a 20ish year old parallel port based webcam he saw on the shelf at a thrift store. It’s a Connectix QuickCam and was the first webcam that did not require a separate video input card to interface with your computer. Due to this feature, the webcam was extremely popular, so popular that Logitech ended up buying Connectix and marketing the camera for themselves.

It’s tough to find a newer computer that still has a parallel port, but using an old computer wasn’t [Andrew]‘s plan anyways. After thinking about it, he decided to try to get the camera’s image to display on a Gameduino 2.

The hardware list is fairly minimal. The cam’s parallel connector is plugged straight into STM32 Nucleo development board by way of several jumpers. The Gameduino 2 is connected to the dev board and a USB to PS/2 adapter was made to power the camera.

2048: Embedded Edition

Embedded touch version of 2048 tile gameHow ’bout that 2048 game? Pretty addictive, huh? Almost as addictive as embedded systems are, at least if you’re [Andrew]. Armed (pun intended) with a Nucleo F4 and a Gameduino 2 shield, he decided to have a go at making an embedded version of the popular tile pusher web game.

If you’re unfamiliar with the Nucleo boards from STMicroelectronics, check out our post on the Nucleo family from a couple of months ago. The Gameduino 2 shield ships with a 4.3″ touchscreen driven by an FT800 GPU EVE. [Andrew] wrote his own driver for it and his blog post goes into great detail about its programming model and the SPI read, write, and command functions he wrote. Full code is available from [Andrew]‘s repo.

He started by generating a blank screen based on clues found in the Gameduino 2 source. Pretty soon he had rendered a rectangle and then a full 2048 board. A minor difference between [Andrew]‘s creation and the original is that his always creates new tiles as ‘2’ while the web game cranks out the occasional ‘4’.

We were unable to embed [Andrew]‘s gameplay videos, but you’ll find two on his blog.
