This software will help you to capture the parallel port data using a small kernel module for Linux. But wait, not only Linux, it also works for Windows, if you use it in a Qemu Virtual Machine under Linux!.
The parallel port sniffer kernel module will create a virtual port for every “real” parallel port in your machine and act like a bridge, re-passing all the commands sent to the virtual port to the real one and capturing the data in real time. The generated output is in the Open Bench Logic Sniffer format and ready to be analyzed with tools like Logic Sniffer which has tools to analyze some known protocols like 1-Wire, I2C, JTAG, SPI, UART, etc.

The Scoreboard project is now finished and working!
The idea of this project is pretty simple: control a ping-pong electronic scoreboard from an Android bluetooth-enabled device.
To do this, I used an ATtiny45 which main function is to display the current scores in a VGA monitor while reading from a bluetooth module UART interface waiting for “commands” that will tell it what to display. The Android device sends the commands via bluetooth, running an application specially designed for this project.
As usual, the whole project is open source, including schematics, AVR firmware and the Android application.
