To protect the board from accidentialy reverted supply voltages the H-Bridge Kit 2Go is equipped with a reverse polarity protection circuit. As with the XMC 2Go the microcontroller can be supplied by the PC via the Micro USB port. To enable standalone operation without a connection to the PC the H-Bridge Kit 2Go also features an on board 5 V voltage regulator which acts a pre-regulator for the 3.3 V regulator of the microcontroller. Attention: The 5 V regulator is a linear voltage regulator and can get very hot depending on the input voltage! VBAT can range from 5 V to a maximum of 36 V without damaging the board. However, since the power dissipation of the 5 V regulator strongly increases with the input voltage it is recommended to keep VBAT below 15 V or to provide additional cooling by attaching a heat sink to the back side of the board. Another option when applying a higher VBAT is to provide 5 V externally at the V5V input of the board. This will relieve the on board regulator and enable operation up to 36 V, the maximum supply voltage of the IFX9201. 2.2 Selecting a DC motor The IFX9201 can drive small DC motors with peak currents of up to 6 A. The achievable continuous drive current is lower and depends on supply voltage, switching frequency and the cooling conditions. Realistic continuous drive currents for this kit are in the range of 1 A to 2 A. Many motors for toys, RC models or robotics fall in this range. 2.3 Connecting the Kit To get started with the Kit just connect a suitable DC Motor and the power supply as shown in Figure 3. The power pads are spaced with a 2.54 mm pitch. Each power signal (except V5V) is occupying two pads. Therefore it is possible to use either 2.54 mm or 5.08 mm spaced connectors or screw terminals. Figure 3 Connecting Motor, Supply and USB Cable Board User Manual 4 Revision 1.3 2016-10-19 H-Bridge Kit 2Go Evaluation Board for DC Motor Control with the IFX9201 Getting Started 2.4 Software The kit comes pre-programmed with a simple example routine that applies a 1 kHz PWM signal to the motor and ramps the speed of the motor up and down by increasing and decreasing the PWM duty cycle. When reaching a duty cycle of 0% it reverts the rotation direction of the motor and starts again with ramping the motor speed up and down. There is demo code available which can be downloaded at http://www.infineon.com/h-bridge-kit-2go. See chapter 3 for more details. This program was generated using the Infineon code development platform DAVE™ (Version 4). For information on this tool, how to use it and for downloading please visit http://www.infineon.com/dave. 2.5 Port Assignment When writing your own routines for driving the IFX9201 please refer to the IFX9201 data sheet and the following port assignment of XMC microcontroller ports (see Table 1).

It has extended functionality to control the H-Bridge Kit 2Go with a PC using the Terminal interface. This chapter describes the firmware update process using DAVE™, the setup of the terminal program and the available commands. 3.1 Device discovery Make sure the J-Link driver is installed properly. This is included in the installation of DAVE™ (see http://www.infineon.com/dave). For more details on J-Link please visit www.segger.com. Then connect the H-Bridge Kit 2Go to the USB port of your PC. The driver for the H-Bridge Kit 2Go will now be installed (this may require administrator priviledges). Check in the “Device Manager” that the “JLink CDC UART Port” has been installed correctly; it should look like Figure 4 (the number of the COM Port may be different). Figure 4 3.2 Correct installation of JLink UART Port Firmware update using DAVE™ After download and extraction of the firmware example, do the following in DAVE™: In DAVE™, go to “File” – “Import”. Then select “Infineon” – “DAVE project” and click “Next”. See Figure 5 for details.

Keep “Copy Projects Into Workspace” checked (see Figure 6). Figure 6 Import project (2) Now the demo project will be imported. The screen should look like in Figure 7. Board User Manual 7 Revision 1.3 2016-10-19 H-Bridge Kit 2Go Evaluation Board for DC Motor Control with the IFX9201 Demo operation Figure 7 DAVE Screen after import of demo project Now connect the H-Bridge Kit 2Go to a USB port (unless already done). You should see one of the red LEDs go on and off (5s on, 5s off, …). Click on “Generate Code” and “Build Active Project”. Then click on the “Debug” button. The following screen will appear (see Figure 8). Board User Manual 8 Revision 1.3 2016-10-19 H-Bridge Kit 2Go Evaluation Board for DC Motor Control with the IFX9201 Demo operation Figure 8 Debug Configuration Again, click on “Debug”. There may be a recommendation to update the J-Link interface. If you decide to go for the update, you will need to click “Debug” again after the update is complete. Then the new demo firmware is installed on the board. 3.3 Operation via Terminal interface Open the Terminal software. Select the serial interface and “JLINK CDC UART Port”. See Figure 9. Board User Manual 9 Revision 1.3 2016-10-19 H-Bridge Kit 2Go Evaluation Board for DC Motor Control with the IFX9201 Demo operation Figure 9 Select “JLINK CDC UART Port” The port now needs to be configured according to Figure 10.
