1) What tools do I need to develop my own programs on the Xminilab?

Besides the power supply, you need an external programmer, such as the AVR ISP 2, or a debugger, such as the AVR JTAGICE mkII or the AVR ONE!.

Software Tools:

2) Can the waveform generator and the oscilloscope run simultaneously?
Yes, once the waveform generator is set, it runs on the background (The AWG uses the DMA, so it doesn't need any CPU intervention). Any of the other application can run simultaneously.

3) How do I power the Xminilab?
To power the Xmegalab you will need a 6V, 200mA wall adapter such as: EPS060100-P5RP

4) Why is the XMEGA powered with 3.5V and not 3.3V?
For compatibility with the Xmegalab, although the digital power could be 3.3V.

5) What is the maximum frequency that I can measure with the Xminilab?
The analog bandwidth is set at 300kHz. However, you can still measure frequencies up to almost Nyquist/2,  i.e. 1MHz. The FFT analysis will be particularly useful to measure high frequencies.

6) The source code says "evaluation version", can I get the full version?
The full source code is currently not open. The evaluation source code does not contain the MSO application. The HEX file does contain the full version of the oscilloscope.

7) What is the current consumption of the Xminilab?

8) What is the difference between the Xminilab and the Xminilab-B?
The Xminilab-B uses a 128x128 LCD and has a buzzer. The Xminilab has a 128x64 LCD and does not have a buzzer.

9) The LCD is blank, what may have happened?
Adjust the contrast potentiometer. The contrast is adjusted during assembly and doesn't need to be changed.

10) There is a new firmware for the Xminilab, how do I update?
Follow these instructions..

11) How does the Xminilab compare to other digital oscilloscopes?
You can check this comparison table.

You should get a Nobel Prize for the Xprotolab.  Way cool.  So happy I chose this scope.
