Supported IMU:
Razor 9DoF: http://www.sparkfun.com/products/10736
Mongoose 9DoF: http://store.ckdevices.com/products/Mon ... nsor-.html
(USE ONLY THE 16MHz CRYSTAL IMU ONLY)
These supported IMUs needs firmware to be loaded into them before they can work properly. Please download the IMU firmware below. Arduino software is needed to upload the IMU firmware to the IMU. Please see link: Arduino-0023 found here: http://arduino.cc/hu/Main/Software
A USB-TTL converter such as this (http://www.ebay.com/sch/i.html?_nkw=dra ... m270.l1313 ) is needed for Arduino to move the IMU files to the IMU. From the TTL you must connect TX to IMU TX, TTL RX to IMU RX, TTL (+) to IMU 3.3v (please see note below) and TTL GND to IMU GND
Note: TTL is 5v and IMU is 3.3v but this did not harm the Razor 9DoF IMU.

Re: IMU Support for DragonOSD+ v2
Download the IMU file and unzip them to your hard drive. Open Arduino then in the "Tools" menu, select "Board" then scroll down and select "Arduino Pro or Pro Mini (3.3V, 8 MHz) w/Atmega328 for the RAZOR 3DoF IMU "OR" "Arduino Pro Mini (5V, 16MHz) w/ATmega328 for the MongooseIMU .

Re: IMU Support for DragonOSD+ v2
From the top screen of Arduino select "File", then "Open". Select the proper IMU files. Usually it is the same name as the IMU folder itself.

Re: IMU Support for DragonOSD+ v2
1) Press "upload"
2) When the message displays in the black box below, "Binary Sketch size..... ", quickly press the IMU "reset button."
Note: Razor IMU red and green LED will light up solid when the firmware has been loaded properly.

Re: IMU Support for DragonOSD+ v2
If you receive a avrdude message in the black box of Arduino, this may mean you have connected the IMU incorrectly!

Re: IMU Support for DragonOSD+ v2
Once the firmware is loaded into your IMU and you did not receive an error message in Arduino, unplug the wires and connect the IMU to the Translator board and OSD.
Power up the OSD, enter into menu mode and activate your artificial horizon by selecting values from 1 and up. Factory setting is (0) which is off.
