angular speed and gyrometer

[fefenin]

hi,
i m a beginner with picbasic ,
i'm actually using a head mounted display (iglasses) and i'd like to make a gyro track sensor,i've got my program running with a tokin sensor on a 10bits adc from pic 16f88 i can display the value of the sensor but i really don t have a clue how to change this value (around 459) to an angle.

looks like i have an angular speed proportionnal voltage out of my sensor
the center value is 2.200 volts and when i move the sensor one way at different speed i can change this value +or - of 2.200


can anybody help me??

ps: i did google around a search on this web site but i didn 't found anything serious

i m sorry for my very basic english!

thank's

Does that sensor have a type number or a brand name. Maybe that than a point to look further for the data!

yep it does have something:

tokin 5AB1
tokin website had some datasheet for devices close to mine but not quite the same

all i know is that it is powered with 5v and the static output is around 2.4v

here there is a linkhttp://www.pgoelz.com/piccolo_piccoboard_troubleshooting_guide.html

my sensor come from this device "the piccoboard" i just kept the sensor itself because the rest of the board was dead

i m sorry but i just realised by reredind the web page taht the new gyro is probably very similar to the one i have exepted it has a 3 volt power suply

here is the link:

my mistake

The spec. says 0,66 mV/deg/sec. maybe this is for your sensor the same value.
This is something you can test by yourselves.

yes i can see that with my oscillospope and stuff but i have no clue how to handle this in my soft
i have an angular rate i just put it in a variable from 10bit adc i can debug it and see the variation when i move the sensor but after what math can i use to transform that in a rotation angle of for example 180° to move a servo??
