Detailed Description

Angle of Attack sensor on PWM.

Author

Jean-François Erdelyi

Driver for a PWM based angle of attack sensor A second sensor can be defined for the sideslip angle It is assumed that both sensors are the same, only sensitivity, offset and direction can differ.

SENSOR, example : US DIGITAL MA3-P12-125-B
