+
+Data download is available using the [MicroPeak USB adapter](../MicroPeakUSB).
## Documentation ##
[html](../AltOS/doc/micropeak.html) and
[pdf](../AltOS/doc/micropeak.pdf) formats.
+## Software ##
+
+The MicroPeak application runs on Linux, Mac OS X and Windows. It
+communicates with the [MicroPeak USB adapter](../MicroPeakUSB) to download and analyze
+flight data. It's written in [Java](http://java.com) and offers the
+same functionality and interface on all three platforms. It uses the
+FTDI USB Serial drivers to communicate with the hardware. If you're
+running Mac OS X or Windows, a compatible version of those drivers is
+included with the software. You can also install a different from from
+the [FTDI Driver](http://www.ftdichip.com/FTDrivers.htm) page.
+
+MicroPeak is part of the larger [AltOS](/AltOS) suite of software, which also
+includes a dedicated [TeleGPS](/TeleGPS) application.
