3.1 Quick Start Setup

TMAG3001EVM TMAG3001EVM With A1 and A2 Still Joined TogetherFigure 3-1 TMAG3001EVM With A1 and A2 Still Joined Together

To set up and use the EVM, follow these steps:

  1. Gently flex the panel at the score line shown in Figure 4-1 to split the board in half for a more compact form factor. This split provides separate boards for the TMAG3001A1 and TMAG3001A2 portions of the original board.
  2. Download and install the driver as a one-time step per PC: https://www.ti.com/tool/download/SBAC253.
  3. Attach the EVM to the Sensor Control Board (SCB). To evaluate the TMAG3001A1 on the EVM, attach header J1 of the Sensor Controller board to header J1_A1 of the EVM (see Figure 4-2). To evaluate the TMAG3001A2 on the EVM, attach header J1 of the Sensor Controller board to header J1_A2 of the EVM (see Figure 4-3).
  4. Use a USB cable to connect the SCB to a PC:
    1. Insert the micro USB cable into the USB receptacle J2 that is on the SCB Controller onboard.
    2. Plug the other end of the USB cable into a PC.
  5. Access the GUI in either the Google Chrome® or Firefox® browser by clicking on the following link: https://dev.ti.com/gallery/view/PositionSensing/TMAG3001EVM_GUI/.
  6. To quickly view results on the GUI, do the following:
    1. Modify the MAG_CH_EN bits in the SENSOR_CONFIG_1 register to enable the desired channels to read from. The GUI has drop-down boxes to configure these bits when the SENSOR_CONFIG_1 register is selected in the register tab of the GUI.
    2. Select the desired result plots under the Results to collect/show box in the Results Data tab, and press Collect Data to trigger the read.
    These two steps are the minimum steps needed to see results in the GUI. However, this assumes that the default register settings are used for the other registers. For more custom settings, modify the corresponding register bits according to the system requirements.
  7. Apply a magnetic field to the sensor by doing one of the following:
    1. Wave the included hand held magnet around the sensor.
    2. Attach the Rotate & Push module to the EVM (see Figure 4-12). For more details on how to use these modules, see Section 3.2.2.
  8. Observe the outputs in the GUI. See Section 3.2.1.3 for more information on GUI setup and operation.
