2.6 Position Encoder Suite

position_sensor_suite_sprui23.pngFigure 2-5 Position Sensor Suite

The Position Encoder Suite provides a range of position encoder and sensing interfaces such as the following:

  • QEP
  • Resolver
  • Sin-Cos
  • EnDat / BiSS

TI designed each interface separately. All interfaces can be used simultaneously, except EnDat / BiSS. EnDat / BiSS cannot be used simultaneously without other interfaces because they share resources.

NOTE

Software support for encoders other than QEP will be provided in a future release of MotorControl SDK.
