xmega mk II

get started.... fast!

The xMega was developed to provide an affordable quick-start platform for data acquisition and embedded control. Using a proven base board with a serial communications interface, in-circuit programming header, voltage regulator, and a real time clock, custom circuit boards can be jumpered on and prototyped rapidly, or custom one-off solutions can be packaged together. Use our code samples & development guides to get moving quickly.

xMega Features:

RS232 serial communication port
Dallas Semiconductor DS1302 Real Time Clock w/Supercap backup
Self-programming with integrated bootloader
8 channel 10-bit analog/digital conversion
Up to 32 channels of GPIO
Onboard ISP header for programming
All onboard IC's socketted
External regulated 5V out, TVS protected input

no isp programmer required:

All xMega boards are self-programming and come pre-configured with a AVRProg-compatilble bootloader.

Programming is as simple as connecting your xMega, hitting the reset switch, and launching AVRProg. AVRProg is part of Atmel's AVR studio package. No other external inputs or signals need to be generated.

application samples:


Palm Device Interfacing: Example application covers reading analog values and toggling the state of a I/O lines from a palm handheld device. Includes source code. Based around the Palm Data Acquisition article published in Circuit Cellar 159. (html)

tested code samples:

The samples below consist of documented source code, a schematic diagram, and a compiled hex file that is compatible with the xmega board running at 4mhz. Read the introductory notes in the .c file for more details, or see xtal's avr guide for more information on AVR programming.

Basic Serial Communication: Covers basic sending and recieving of serial data from a terminal program and the xMega board. (serial.c, zip)

Real Time Clock Interfacing: Shows how to set and display the current time via a serial communications link. Sets up a bit-bang interface to the DS1302 RTC to set & retrieve current time. rtc.c, zip)

ADC Setup & Sensor Reading: Shows how to set up the analog/digital converter, read the temperature from a LM34 temperature sensor, and send the temperature to the serial port. (adc.c, zip)

Hardware PWM output: Demonstrates the mega's hardware PWM output. (pwm.c, zip)

Hardware Interrupts: Trigger LEDs based on a hardware interrupt (interrupt.c, zip)

Alarm Clock: Uses the real time clock and a serial link to light the onboard LED on demand. (alarm.c, zip)
