Gyroscope Variables

Headset Gyroscope Variables

These values are populated by sending interrupt requests to interface 8 on the headset. The headset returns a hex string which is then broken up into an array. The array can vary in length 131, 155, 203, 227, 683, 1019, the most common length is 155. Longer values than 203 seem to have 0s and no data in them. Values seem to be 16-bit unsigned Integers. from -9000 to +9000.

Button Values

Location	Values/Range	Description	Purpose/Notes
0	0 or 1 (1 is on)	Video In	Tracks if the headset is Receiving Video Input
1	0 or 1 (1 is on)	Head	Tracks if the headset is on your Head or not
2	0 or 1 (1 is on)	Button	Tracks if the headset button is pressed
