3.2.2 Rotate and Push Demo

The TMAG3101EVM can be used with the Rotate and Push 3D print (sold separately). To use the Rotate and Push Demo, follow these steps:

Attach the Rotate and Push Module to the EVM (see Figure 3-11 for an example on how this module is connected to the EVM).

  1. In the GUI configuration page:
    1. Select the desired operating mode from the operating mode drop down (SENT, Triggered SENT, Analog, or PWM).
      1. Make sure the drop-down menu option for the MAG_CH_EN register bits says X, Y channel enabled.
      2. Make sure the drop-down menu option for the ANGLE_EN register bits says X-Y angle.
      3. Make sure the drop-down menu option for the DATA_SEL register bits says 2D angle (no magnitude) or 2D angle and magnitude (SENT only)
      4. Make sure to use either the 100mT or 150mT variant. Note that the demo is not able to work with the 50mT range because the magnetic flux density produced by the Rotate and Push Module is greater than 50mT, which is why the 100mT range is selected.
    2. Click "Program Device" to force the TMAG3101-Q1 into the selected operating mode.
  2. Go to the Plots tab inside the Results Data page (see Figure 3-12).

  3. Select Collect Data to see the resulting device angle measurement and magnitude, if enabled, (Figure 3-13) during this process.

  4. Select the STOP COLLECT button to stop collecting data.
