1 Introduction
The XK-1A is a low-cost development board based on the XMOS XS1-L1 device. It
includes a single L1, four LEDs, two press-buttons, SPI flash memory, two 16-way
IDC connectors and an XSYS debugging interface.
This tutorial shows you how to write some simple XC programs that control and
respond to the XK-1A board components. In this tutorial you learn how to:
· illuminate the LEDs
· flash the LEDs at a fixed rate
· flash the LEDs in sequence
·
respond to a button press
· connect multiple boards together
2 Illuminate an LED
This part of the tutorial shows you how to illuminate an LED on your XK-1A, using
an XC port and an output statement.
2.1 Create a project
2.2 Add the application code
The program below illuminates an LED on an XK-1A.
