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.
