Not a bad idea, if the mods are OK with it. I obviously can't update the first post in this thread....
Ultimately the website should be your source; I would prefer this to be the "official" place to go, rather than my personal website or Rob's blog, not that the latter isn't interesting or useful.
You've got ordered sections on building it and using it. There's also a PDF guide in the downloads section for flashing, although it is awkward to have to update two sets of information so I'm not sure how long that will survive over the coming software updates, or I move to just doing the PDFs and make the website instructions very high-level. You can also search it, of course.
In short :
You can make your own on breadboard, you can etch your own PCB, you can buy our PCB and put it together yourself or you can buy one built for you on a voluntary, no-guarantees basis
- Flash It with Calibration Sketch
Preferred option is the UpdateTool (and very, very soon Rob's UberGUI will be released which will do it all for you *excited*) but if you want to use the compiler and code route, follow the instructions on the website
Run up the UI221 against the above sketch (firmware, if you like) and do a simple calibration routine with the device flat and still.
- Flash It with Main Sketch
As per previous point, two methods, depending upon whether you want to about with code compiling or not.
- Calibrate Yaw Drift & Play!
Run up the UI again and this time calculate yaw drift. This will improve your experience, and the yaw drift can be re-calculated any time using the UI if you feel it's not accurate enough. Spending 10 to 20 minutes here can improve things no-end in game.
Once you're done, use it and abuse it
Actually, just use it, please. Gyro abuse is an ever-increasing problem in the modern world. Hundred of Gyro's need re-homing globally every month due to mistreatment - being shook viciously, or being starved of exercise. I've even seen some examples of them being strapped down by elastic bands and left for hours on end.
