+# Installing AltosUI on Windows 8
+
+Windows 8 places additional barriers to installing software beyond
+those present in Windows 7. In particular, trying to use the standard
+Windows USB modem driver on new hardware now requires 'driver signing'
+for the text file that tells Windows to use the driver that it already
+has installed.
+
+Until we figure out what is necessary to make this work the 'right'
+way, here are a couple of pointers to sites that should help you
+install the current AltosUI bits on your Windows 8 machine.
+
+## The official Microsoft link
+
+Here's a link to an official [Microsoft answer](http://answers.microsoft.com/en-us/windows/forum/windows_8-hardware/how-to-install-a-driver-that-does-not-contain/7c3f299b-3483-4c96-8c44-87c7451af222)
+for how you are supposed to get Windows 8 to install Windows 7 drivers.
+
+## An unofficial video link
+
+And here's a (more helpful in my opinion) [video](http://firstpost.com/topic/product/windows-8-how-to-fix-the-third-party-inf-does-not-contain-digital-sign-video-dlYGfJM2BJ0-91565-1.html)
+which will lead you through the necessary steps.
+
+Our friend, Bob Brown from the Kloudbusters used the video
+instructions and reports that things are working just fine now!

MicroPeak is designed to be rugged enough for typical rocketry
applications. It contains two moving parts, the battery holder
and the power switch, which were selected for their
any direction. Because it is a sliding switch, orienting the
switch perpendicular to the direction of rocket travel will
serve to further protect the switch from launch forces.

+ but not using the usual 2x3 array of pins on 0.1"
+ centers. Instead, there is a single row of tiny 0.60mm ×
+ 0.85mm pads on 1.20mm centers exposed near the edge of the
+ circuit board. We couldn't find any connector that was
+ small enough to include on the circuit board.
+ </p><p>
+ In lieu of an actual connector, the easiest way to connect to
+ the bare pads is through a set of Pogo pins. These
+ spring-loaded contacts are designed to connect in precisely
+ this way. We've designed a programming jig, the MicroPeak
+ Pogo Pin board which provides a standard AVR interface on one
+ end and a recessed slot for MicroPeak to align the board with
+ the Pogo Pins.
+ </p><p>
+ The MicroPeak Pogo Pin board is not a complete AVR programmer,
+ it is an interface board that provides a 3.3V regulated power
+ supply to run the MicroPeak via USB and a standard 6-pin AVR
+ programming interface with the usual 2x3 grid of pins on 0.1"
+ centers. This can be connected to any AVR programming
+ dongle.
+ </p><p>
+ The AVR programming interface cannot run faster than ¼ of the
+ AVR CPU clock frequency. Because MicroPeak runs at 250kHz to
+ save power, you must configure your AVR programming system to
+ clock the AVR programming interface at no faster than
+ 62.5kHz, or a clock period of 32µS.

-
-The final board will have an LED to help check alignment between the
-MicroPeak LED and the MicroPeak Serial phototransistor.
-
-## MicroPeak Data ##
-
- * Stored in on-chip 512B eeprom
- * Records raw barometer readings every 192ms
- * Enough storage for 48 seconds
-
-No changes are needed to the MicroPeak hardware, but new firmware that
-includes the data download feature is necessary to use the MicroPeak
-Serial Interface.
-
-## MicroPeak Interface ##
-
-MicroPeak transmits the entire flight log via the LED just after
-reporting the last flight altitude at power up. The data are
-transmitted in regular serial format at 9600 baud.

## Documentation ##
The MicroPeak manual is available in
[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 USB Interface #
+
+The MicroPeak USB Interface board provides a way to capture
+[MicroPeak](../MicroPeak/) flight logs over a USB connection to a
+computer running Linux, Mac OS or Windows.
+
+<a href="v1.0/MicroPeakUSB.jpg"><img src="v1.0/MicroPeakUSB-640.jpg"></a>
+
+## MicroPeak Data ##
+
+ * Stored in on-chip 512B eeprom

+
+No changes are needed to the [MicroPeak](../MicroPeak/) hardware, but new firmware that

+
+## MicroPeak Interface ##
+
+[MicroPeak](../MicroPeak/) transmits the entire flight log via the LED just after
+reporting the last flight altitude at power up. The data are
+transmitted in regular serial format at 9600 baud.
+
+The MicroPeak USB Interface board contains a phototransistor,
+op-amp and serial-to-USB interface chip. It also includes a blue LED
+which blinks in time with the [MicroPeak](../MicroPeak/) orange LED. This makes
+aligning the two boards by hand quite easy.
+
+## MicroPeak Application ##
+
+The MicroPeak application is written in Java application and runs on
+Windows, Mac OS X and Windows. Captures and saves data, provides
+plots and statistics. More information is available on the main
+[MicroPeak](../MicroPeak/) page.
