XC-1A Quick Start Guide (1.0) 2/7
1 Introduction
The XC-1A Development Kit contains everything you need to start exploring the XMOS
event-driven processor technology. It comprises a single XS1-G4 device, 4Mbits SPI
FLASH memory, 16 user-configurable LEDs, four pushbuttons, a speaker, JTAG and
serial interfaces, four expansion areas suitable for IDC headers and a through-hole
prototyping area for connecting external components.
The XC-1A card can be powered by an external 5V power supply, or the USB cable
provided which also provides a JTAG interface between the card and XMOS Tools.

5 XC-1A Pre-loaded Demonstrations
The XC-1A runs pre-loaded demonstration code on power up. The default behaviour
is to twinkle the bi-colour clock LEDs around the XS1 chip and to pulse the LEDs next
to the buttons. Press any of the four buttons to launch a simple demo application.
5.1 Button A: Clock
Displays a clock on the clock LEDs with the hands as follows:
Red Minutes
Green Hours
Orange Seconds
The 12 clock LEDs on the XC-1A provide 5-second resolution. When the clock is
running use the buttons as follows:
A Return to default LED demo
B Speed up clock to set time
C Tick-tock sound on
D Tick-tock sound off
5.2 Button B: Simple Audio Synthesizer
Press buttons B-D to generate different tones. Press A to return to the default LED
demo.
5.3 Button C: Reaction Game
A simple reaction game. The red LED cycles around the clock face. After a varied
delay a LED will illuminate green. The aim of the game is to press button D when the
red LED is over the green LED. The game speeds up as you progress. There are five
levels to the game and the current level is shown on the four button LEDs. Press A to
return to the default LED demo.

5.4 Button D: Simple UART Demo
A simple UART demonstration using the virtual COM port of the XC-1A. Once you
have started the program, connect to it using a standard terminal (such as realTerm
for Windows or GTKTerm for Linux). When you press a key, a list of three commands
is displayed that you can use to illuminate the clock LEDs via the terminal. The UART
settings are as follows:
Bits per sec 115200
Parity None
Data bits 8
Stop bits 1
Flow control None
Press A to return to the default LED demo.
