TPS929160EVM User's Guide
ABSTRACT
This user's guide describes the setup and use of the TPS929160EVM evaluation module (EVM). This EVM
helps the user evaluate the features of the Texas Instruments TPS929160-Q1, which is an automotive 16-
channel LED driver with FlexWire interface, to address increasing needs of individual control of each LED
string. This document includes hardware setup instructions, software instructions, a schematic diagram, a bill of
materials and printed-circuit board layout drawings.
WARNING
Hot surface! Contact may cause burns. Do not touch!
Some components may reach high temperatures >55°C when the board is powered on. The user must
not touch the board at any point during operation or immediately after operating, as high temperatures
may be present.

3 How to Get Started
3.1 Hardware Setup
There are two hardware setups to simulate the communication between MCU and TPS929160-Q1 directly or
through CAN transceiver. And TPS929160EVM contains a buck in the board. You can decide whether to use it
by "J66", "J31".
3.1.1 Communication without CAN Transceiver
Figure 3-1 shows the hardware setup when TPS929120CANEVM is not used. Figure 3-2 shows the jumper
configurations for the TPS929160EVM without TPS929120CANEVM connected. This jumper is the default
jumper configuration shipped with the board.
Figure 3-1. Hardware Setup without CAN Transceiver
• Connect a 12-V power supply to TP1 (VSUPPLY_EXT) and TP2 (GND).
• Connect USB2ANY tool to PC through the USB cable.
• Connect USB2ANY tool to the J4 connector of TPS929160EVM through ribbon cable.

3.3 Firmware Update
After opening the GUI, the GUI tries to connect the EVM board. At the moment, the GUI detects the
firmware version of the connected USB2ANY tool automatically. If the firmware version is not mapping with
the recommended version for the GUI, there is a prompt as shown in Figure 3-9 to help user update the firmware
in the USB2ANY. Click the update button to begin the firmware update process. After firmware update succeeds,
click the finish button to close the prompt window. Then the GUI tries to connect the EVM board again with the
defined device address. After it connects successfully, there is a 3 confirmation sync-up prompt windows, the
connected LEDs type (Monochrome or REG), Fail-Safe state (0 or 1) and EEPROM programming Mode (Chip
select or External address). For each confirmation window, just click on the correct image mapping to the current
EVM setup.
Figure 3-9. Firmware Update Prompt Window
If the firmware version of the USB2ANY tool is lower than 2.8.2.0 there is not firmware update prompt as showed
in Figure 3-9. Upgrade the firmware version to 2.8.2.0 manually. Go to USB2ANY Interface Adaptor web page,
scroll down to "Key Document" section and click "USB2ANY Explorer Software" to download the installation
file. Extract the zip file and install the USB2ANY Explorer using the "USB2ANY Explorer-2.8.2.0 Setup" exe file.
After USB2ANY Explorer installation, open the software with USB2ANY tool connected to the computer. Please
make sure that the GUI is closed while opening the USB2ANY Explorer. After the explorer is opened, there is
a "USB2ANY Firmware Requirement" prompt. Click the "OK" button to continue. Follow the instructions on the
"USB2ANY Firmware Loader" as showed in Figure 3-10 to update the firmware.
After upgrading the USB2ANY firmware version to 2.8.2.0, close the USB2ANY Explorer and open the
TPS929160EVM GUI again. While trying to connect the EVM board, the firmware upgrade window as showed in
Figure 3-9 appears.

3.4 GUI Function
This section provides instructions to run the TPS929160EVM using the TPS929160EVM GUI.
3.4.1 Connection Status
Make sure to power up the EVM board and connect it to the PC through USB2ANY tool before opening the
on-line version GUI or desktop version GUI. If the GUI has been opened but the USB2ANY has not been
connected to the PC, make sure the USB2ANY has been connected to the powered-up EVM board when
plugging it into the PC. Other operation orders may lead to the GUI working abnormally. After this action
happens, please refresh the on-line version GUI or re-run the desktop version GUI.
The GUI supports both hardware setups with CAN board connected or not connected. When CAN board
connected, the CAN checkbox on the "Device Address" widget must be checked. When the CAN board is not
connected, leave the CAN checkbox unchecked. Before changing hardware setup, remove the USB2ANY cable
plug from PC.
Before using the GUI, make sure the hardware is connected successfully. Check the connection status on the
home page where there is a green check mark on the left side of the TPS929160-Q1 body, which means the
USB2ANY is connected to the computer successfully. If there is a red X mark, it means the hardware is not
connected. Reconnect the device.
After hardware is connected, either "Hardware Connected" or "Hardware not Connected" shows on the bottom
left corner of the GUI. The button to connect or disconnect the GUI to hardware is also available there. Click
the button to connect to hardware if hardware is not connected or to disconnect from hardware while hardware
connected.
To connect the GUI to device successfully, set the correct device address on the GUI to map the real device
address. See the TPS929160-Q1 12-Channel Automotive 40-V High-Side LED Driver with FlexWire data sheet

for instructions to set the device address. The default device address setting value of the GUI is 0x01 when you
open the GUI.
On the EVM board, the ADDR0, ADDR1, ADDR2and ADDR3 can be configured as High or Low through "J62",
"J63", "J64"and "J65" connectors. On the GUI page you can directly enter the specified value through the
"Device Address" widget.

3.4.2 LED Control Page
Figure 3-12 shows the registers page.On the left side, you can select one or more channels to control. On the
right side, you can change the current and PWM of the selected channel. The ADC value and error flag is shown
on the right. The green button called "Device Configuration" is used to make an advanced setup.
