Overview - FIGnition FUZE Hardware Reference Manual

1 Overview

The FIGnition PCB contains 51 components connected by ground planes; power and sig-
nal traces. The signals wind their way across the PCB to the various building blocks as
shown on the left and as a block diagram on the right.
USB Audio
Keypad
These blocks are:
1. Keypad. The keypad allows you to type in programs; enter data and initiate a firmware
upgrade.
2. Video. The Video Phono outputs composite video to a TV.
3. Audio. The Audio Phono provides Audio In/Out.
4. Flash. The External Flash memory is where all your programs are stored when the
computer is switched off.
5. RAM. The external RAM chip is loaded with a program and the program runs from it.
6. USB. The connector is used to power a FIGnition and upgrade the firmware as FIGni-
tion is improved.
7. The AVR Microcontroller. The Avr Microcontroller is the 'brains' behind it all. It contains
an 8-bit processor for running internal firmware and the internal firmware implements a
built-in programming language and the code that manages the USB, Audio, Video,
Keypad, Storage and RAM.
