Preliminary
The XMultiKit is a multi purpose development board using the XMEGA AVR microcontroller.
The XMultiKit is also a fully featured Mixed Signal Oscilloscope (MSO) with Spectrum Analyzer and Arbitrary Waveform Generator (AWG).

Welcome screen options:
A Lissajous curve will be drawn on the screen. Use the rotary encoders to change the curve parameters.
Below the AVR logo, it will be displayed the keys pressed on the keypad, and the characters received on the serial port.
The serial port setting for the XMultiKit are: 115200 bps, 1 start bit, 1 stop bit, no parity, no hardware control.
Buttons KA thru KE will start the corresponding application
The XMultiKit requires a DC power supply of 6V, 250mA.
To power on the XMultiKit, press KA for at least half a second, you will hear two clicks.
To power down the XMultiKit, press KA for at least 2 seconds. You will hear the power down sound.
If using an external programmer, KA needs to be pressed while programming the XMultiKit.
Pressing # on the welcome screen will activate the test mode.
During the test mode:
- Data from CH1, CH2, Logic, and the AWG is visible on the screen.
- Data from the Serial port is displayed on the screen.
- When pressing buttons on the keypad, the corresponding character is sent to the serial port.
- Pressing KA will execute the offset calibration function. CH1 and CH2 must be connected to ground.
?
To develop your own application for the XMultiKit, you will need an external programmer, such as the AVRISP mkII, the AVR JTAGICE mkII or the AVR ONE!.
The XMultiKit will soon have a bootloader, so that firmware updates can be done via the serial port.
