3D Magnetic Sensor 2 Go evaluation kit
Introduction

Introduction
Infineon’s 3D Magnetic Sensor 2 Go is a compact evaluation kit to familiarize the user with the 3D Hall sensor
TLV493D-A1B6. In a short time the board is set up and own 3D magnetic measurements can be executed. All
required hardware is included and the software can be downloaded for free from the Infineon web page.
This user manual describes the different parts of the board, the software installation process and clarifies how
the Graphical User Interface (GUI) can be used to do first evaluations. Further it is shown where to find example
code and an Arduino library as a easy starting point for own developments.
1.1
Hardware overview
The 3D Magnetic Sensor 2 Go kit contains:
•
The 3D evaluation board (EvalBoard) as shown in Figure 1, a ready-to-use printed circuit board (PCB) with
the 3D Hall sensor. The EvalBoard is based on the XMC2Go-Kit. More technical documents and detailed
description can be found at http://www.infineon.com/xmc2go
•
A standalone 7x7x5 mm ferrite block magnet
To use the 3D Magnetic Sensor 2 Go kit the user has to acquire a USB cable with a micro USB connection-end for
the EvalBoard side and a conventional USB connection for the PC side.

Software
The required software to run the kit can be found at the Infineon web site. For further information refer to the
chapter Software installation.
The software package contains:
• A Graphical User Interface (GUI) for sensor evaluation.
• Firmware to be flashed into the XMC microcontroller for the low level communication with the sensor.
•
USB driver J-Link from Segger which is necessary to establish the USB connection.
This software was designed to be used with Windows 7 and Windows 10. It is compatible with both 32-bit and
64-bit system types. Backward compatibility with older Windows versions is ensured only by the .NET platform
as specific tests were not conducted on older operating systems.
The USB protocols capabilities are defined by the Segger driver. Versions USB 2.0 and USB 3.0 are compatible.
The GUI is used to enable a communication between the sensor and the PC. The user can configure the sensor
to operate in different modes. In those modes the update rate of the magnetic field measured (X, Y and Z
components) and current consumption vary.

EvalBoard description
2.2
Optional external power supply
The 3D Magnetic Sensor 2 Go EvalBoard is supplied via the USB cable. It is also possible to provide an external
power supply. If this is the case, a few considerations must be taken into account as described below.
The 3D Magnetic Sensor 2 Go EvalBoard must be supplied by external 5 Volt DC power supply connected to the
micro USB plug. The voltage regulator shifts the voltage level to 3.3 V for the microcontrollers and the 3D
magnetic sensor. The Power & Debug LED indicates that the presence of the generated 3.3 V supply voltage.
Out of the box with the pre-programmed application and the on-board debugger in operation the EvalBoard
typically draws about 75 mA. This current can be delivered via the USB plug of a PC, which is specified to deliver
up to 500 mA. An on-board reverse current protection diode will ensure safe operation and protects the USB
port of the Laptop/PC in case power is provided through the pin header X1.
It is not recommended to apply an additional power supply to the VDD pin of X1 (3.3 V) when the board is
powered via USB, because the 3.3 V supply could drive against the on-board power supply. The VDD pin can be
used to power an external circuit. But care must be taken not to draw more current than 150 mA, which is the
maximum current the on-board voltage regulator can deliver. After power-up the Debug LED starts blinking. In
case there is connection to a PC with correctly installed drivers, the Debug LED will turn from blinking to
constant illumination.

microcontroller in the TSSOP-16 pin package. The pinning table is also printed onto the bottom side of the PCB
(depending on the version). The pin header X3 can be used to access directly the 3D magnetic sensor pins.

3D magnetic sensor evaluation
This chapter describes how the GUI can be used to make first evaluations with Infineon's 3D magnetic sensor.
4.1
Getting started
Once the software is installed, the following steps are necessary to do the first magnetic measurements.
Steps
1.
2.
3.
Connect the EvalBoard to the PC via the USB cable. Use the micro USB port for the EvalBoard and USB
port for the PC. The power LED on the EvalBoard will switch on, indicating the EvalBoard is supplied with
enough power.
Open the 3D 2Go GUI by clicking the shortcut in the start menu. On the top left side you should find the
XMC2Go board in the list. If not, check that the EvalBoard is correctly connected to the PC and the J-Link
driver is installed. Click on the Connect to selected programmer button which is marked in Figure 27 to
establish the connection with the 3D Magnetic Sensor 2 Go kit. The first time you connect the board, a
firmware will be downloaded to the XMC1100 which takes short time. This is indicated by the blinking
power LED on the EvalBoard.
Figure 27
Establish the connection to the EvalBoard
The GUI automatically detects the sensor type on the 3D Magnetic Sensor 2 Go kit. Different
configuration modes can be selected which are briefly described in Table 4 . For details refer to the
TLV493D-A1B6 data sheet and user manual. After you have selected the mode, click on Start to begin
with the measurements.

The graph view displays the magnetic field measurements in X, Y and Z direction.
Figure 28 shows the graph view window. On the left hand side there are three histograms which plot the
magnetic field for each measured sample. On the right a table displays all measured data, including the
temperature. With the save button it is possible to export the measurement data into a .csv file. This is
especially helpful for processing the data afterwards. .
If a new mode should to be evaluated click the Stop button on the left control panel. Save the data and Clear it.
Select a new configuration and click again on Start to begin the new evaluation.

Joystick view
The joystick view is a virtual representation of a real joystick with an attached magnet, mounted above the 3D
magnetic sensor.
It is intended to be used with the Joystick adapter available for the 3D Magnetic Sensor 2 Go kit. For order
details and information about the used magnet refer to section Hardware extensions .
The software measures the magnetic field in all three dimensions and calculates the angles necessary to
determine the joystick position. Further information is given in the application note "Infineon 3D Magnetic
Sensor - How to Make a Magnetic Design for Joystick" which can be found on the Infineon home page.

Rotation view
In this view the calculated spherical coordinates of the magnetic field are displayed. Additionally it includes a
graphical presentation of the 3D Magnetic Sensor 2 Go rotary knob attachment .
The polar coordinates consist of the radius r as well as the angles Phi and Theta. They are calculated out of the
measured three dimensional magnetic field with following equations:
r = Bx 2 + By 2 + Bz2
Bz
Phi = arccos
r
By
Theta = arctan
Bx
Below the polar coordinates a virtual rotation knob can be found. It can be used with the rotary knob
attachment described in Hardware extensions. When the user turns the hardware knob, also the indicator in
the GUI turns. This is achieved by measuring the magnetic field and calculating the angle between Bx and By as
described above. Also a push functionality is implemented depending on the radius r of the magnetic field.

Linear movement
This view is meant to be used with the linear slider extension. It allows to measure the position of the magnet in
a slide by configuration.

Out of shaft
This view is meant to be used with the out of shaft extension. It allows to measure the angle of the magnet while
the sensor is placed at the side of it.

Additionally to the graphical user interface a low level library is provided as a quick entry point for own
developments with the 3D magnetic sensor. It can be downloaded from the link below.
https://www.infineon.com/cms/de/product/sensor/magnetic-sensors/magnetic-position-sensors/3dmagnetics/#!tools
The library comes with a generic C code example as well as a specific implementation for the XMC based 3D
Magnetic Sensor 2 Go kit. An comprehensive documentation can be found under the respective "doc" folder.
