[ Hardware: Guides | HOW TOs ]

Raspberry Pi Hacking. This paper outlines Raspberry Pi hacking, GPIO headers and
how to interface them. Along with various programming language libraries and
example code for controlling the GPIO pins and various applications they can
be used for.

Also covered will be performance tweaks and enhancements you can do to
improve the performance of RAM, CPU and DISK I/O of the Raspberry Pi.

Languages covered for controlling the Raspberry Pi GPIO pins: C, C#,
Java, Perl, Python, Ruby, Shell Scripting and the wiringPi library.

In this document interfacing with a Teensy Kit is covered
and interfacing the Raspberry Pi with a HD 44780 LCD display,
using the RPi.GPIO

Recently added: Using a 16bit MCP23017 I2C I/O Expander with Raspberry Pi

Scan Key Code mappings for a 101 Key keyboard, including numpad and some special
keys.

Tutorial on analyzing, reversing and emulating firmware using tools like Binwalk,
Firmware modification Toolkit & Qemu.

Note: This will only work for devices that are of the following:

A. Under 12volts.
B. Support ONLY 10/100 speeds.

This will NOT work with gigabit devices as gigabit requires
all 8 pairs.

WARNING: This mod will FRY gigabit devices

HOWTO on building your own parallel port to LCD interface, driven by lcdproc.

Tutorial on how to convert your Eagle Board Drawings into usable images for creating
your own PCB boards using the Toner Transfer Method.

Note: Assumes prior knowledge of eagle and prepared schematic and board drawing,
works best when the circuit does not use any SMD chips.
