-AltOS is the name of Keith's firmware "operating system" for
-Altus Metrum products.
+# Introducing MicroPeak by AltusMetrum #
-In addition to the firmware for hardware products like
-[TeleMetrum](../TeleMetrum), [TeleMini](../TeleMini), and
-[TeleDongle](../TeleDongle), the AltOS source tree also
-includes AltosUI, which provides for flight monitoring, post-flight
-analysis, device configuration and firmware updating. AltosUI runs on
-Linux, Mac OS X and Windows. It's written in [Java](http://java.com)
-and offers the same functionality and interface on all three
-platforms. A small platform-specific library communicates with the USB
-interface on the Altus Metrum devices.
+Micropeak is a barometric logging altimeter for precision model
+rocketry altitude measurements.
-There are also Linux-specific tools that provide lower level access to
-the devices which are useful for developing firmware for the devices.

-We maintain a list of [launch site GPS coordinates](launch-sites.txt). If
-your favorite launch site isn't included, please let us know!
+Production units are available from the
+[Garbee and Garbee](http://auric.gag.com/index.php?route=product/product&product_id=80)
+web store and [Apogee Components](http://www.apogeerockets.com/Electronics_Payloads/Altimeters/MicroPeak_Altimeter)
-## Available Versions ##
+Data download is available using the [MicroPeak USB adapter](../MicroPeakUSB).
-There is a single manual for most Altus Metrum products, which is available
-in [html](doc/altusmetrum.html) and [pdf](doc/altusmetrum.pdf) formats.
+## Documentation ##
-We also have an AltOS internals document for programmers
-in [html](doc/altos.html) and [pdf](doc/altos.pdf) formats, and a
-document describing the AltOS over the radio protocol
-in [html](doc/telemetry.html) and [pdf](doc/telemetry.pdf) formats.
+The MicroPeak manual is available in
+[html](../AltOS/doc/micropeak.html) and
+[pdf](../AltOS/doc/micropeak.pdf) formats.
-If you're running Windows 8, you should take a look at [Installing AltosUI on
-Windows 8](Win8) which will help you install the operating system
-drivers needed to communicate with the USB hardware.
+## 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.

-## Source Code ##
-
-The latest source, which may include unreleased work in progress, is always
-available from [git.gag.com](http://git.gag.com)
-in the project [fw/altos](http://git.gag.com/?p=fw/altos;a=summary).
-
-We've gathered a few notes on [buidling AltOS](building).
-
-## Future Plans ##
-
-Bug reports, feature requests, and planning for AltOS releases happens
-on the [Altus Metrum Trac Site](http://trac.gag.com/altusmetrum).
-
-A number of features are implemented or in process in the sources available
-in our publicly visible repository that are not part of the current stable
-release.
-
-* Motor characterization. Because TeleMetrum contains a
- high-resolution, high-frequency accelerometer, it is possible to
- take the data from that and compute an accurate thrust curve for
- the motor.
-
-* Comprehensive PDF and/or HTML -based flight report. Construct a
- complete report of the flight suitable for publication on the web
- that includes graphs of the flight and details about motor
- performance etc.
-
-* Publish flight data to the Altus Metrum web site. This will allow
- you to share your flight data with others, and let you download
- flights published by others.
-
-There are any number of additions that could be made to this list; feel free
-to send along ideas that you’ve got. Of course, all of this software is
-licensed under the GNU General Public License, so you can get the source and
-hack on it in the comfort of your own home.

-## Platform Specific Notes ##
-
-### Linux ###
-
-If you use [Debian](http://www.debian.org), you can simply install the 'altos'
-package from any Debian mirror, like so:
-
- apt-get update
- apt-get install altos
-
-If you use [Ubuntu](http://ubuntulinux.org), pre-built packages are available
-from [this PPA](https://launchpad.net/~sconklin/+archive/altos/)
-maintained by Steve Conklin and friends.
-
-If you use some other distribution of Linux, then
-a Linux package of our second-generation Java bits that
-should run on any distribution with a modern Java version is also
-available. Unlike the Debian pacakge, which depends on various libraries
-already part of the Debian distribution, this package includes a "fat" jar
-file with all of the Java libraries that aren't part of the basic Java runtime
-environment included, so it should "just work" on any system with
-Java 6. Development and testing is done with OpenJDK 6, but current
-downloads from [java.com](http://java.com) should be fine too.
-
-If you'd rather build from source, our source tree includes documentation on
-how to build packages for various
-Linux systems such as [Arch Linux](http://www.archlinux.org), and the
-debian/ directory contains all the control
-files for building the Debian packages on other architectures or derivatives
-such as [Ubuntu](http://ubuntu.com).
-
-Bdale has also created a theme for
-[GDM](http://projects.gnome.org/gdm/) that he uses on his primary notebook,
-and the
-[Simple Login Manager](http://slim.berlios.de/) that he uses on all of his
-other machines and which is ideally suited for machines dedicated to AltOS
-ground station use. It includes a photo of a drag-race between
-nearly-identical rockets
-built by Keith and Bdale, that was the first time either of us gave TeleMetrum
-complete control of a rocket flight without some other backup! See the themes/
-directory in the source tree (the themes are included in the Debian package).
-
-### Mac ###
-
-A Mac OS X package that is compatible with versions 10.5 "Leopard" and
-later. The Mac operating system includes Java, and all Altus Metrum products
-show up as simple USB serial ports, so this should just work with no
-additional drivers or other dependency issues. Older versions of the Mac
-operating
-system, and even newer versions for PowerPC-based machines, come with
-Java version 5 or older, which is too old for use with Altus Metrum
-software. We know of no way to update the Java version other than
-upgrading to a newer operating system (for Intel based macs) or
-purchasing new hardware (for PowerPC based macs).
-
-If you have trouble installing on a Mac, and are getting errors about the
-package being corrupt, you may not be configured to allow installation of
-software from arbitrary sources. One customer running 10.8.1 reported that
-he was able to work around this by going to "System Preferences", "Security
-& Privacy", "General", and then clicking the "Anywhere" radio button where
-it askes "Allow applications downloaded from:".
-
-### Windows ###
-
-Our Windows package is known to work on at least some flavors of XP, Vista, and
-Windows 7 Enterprise. If you don't already have Java installed,
-download and install a current Java 6 version from [java.com](http://java.com)
-first. Then download our installer and run it. Windows already has
-the required USB serial device driver, and our package should do the right
-things to bind it to our devices, but if you get a complaint about the device
-being unrecognized, try pointing to the copy of the telemetrum.inf file
-included in the package directory manually.
-
-Note that on some Windows 7 systems, it may be necessary to install AltOS using
-'compatibility mode'. You can set this mode by
-[changing the properties](http://www.sevenforums.com/tutorials/316-compatibility-mode.html)
-of the installer .exe.
