- * On EasyTimer v2, bmi088 pin 1 (NE corner of chip) is placed towards the
- * USB and antenna edges of the board. Relative to bmi088 specs, to

  *
- *	+along		+X	+roll	+X
- *	+across		-Y	+pitch	-Y

+ *
+ * +along	nose up
+ * +across 	switch screws down
+ * +through	TH down
+ *
+ * With the board aligned to have positive accel for the relevant
+ * axis, looking down from above we have:
+ *
+ * +roll	counter clockwise (nose up)
+ * +pitch	counter clockwise (switch screws down)
+ * +yaw		counter clockwise (TH down)
