TPS929120EVM User's Guide

This user's guide describes the setup and use of the TPS929120EVM evaluation module (EVM). This

EVM helps the user evaluate the features of the Texas Instruments TPS929120-Q1, which is an

automotive 12-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.

3.1.2 Communication with CAN Transceiver

Figure 4 shows the hardware setup when TPS929120CANEVM is used. Figure 5 shows the jumper

configurations for TPS929120EVM with TPS929120CANEVM connected. With this setup, the clock and

PWM signal terminals from the USB2ANY are disconnected to such signal terminals of the TPS929120-

Q1 device on the TPS929120EVM. As a result, an extra instrument for generating the PWM or clock

signal is required to simulate the external PWM or clock input to TPS929120EVM, because both signal

outputs from USD2ANY board are not transmitted to TPS929120EVM if TPS929120CANEVM is

connected.

Figure 4. Hardware Setup with CAN Transceiver

• Connect a 12-V power supply to TP1 (VSUPPLY_EXT) and TP1 (GND).

• Connect USB2ANY tool to PC through USB cable.

• Plug TPS929120CANEVM to USB2ANY tool through the J3 header of TPS929120CANEVM.

• Connect TPS929120CANEVM to TPS929120EVM through the J4 connector of TPS929120CANEVM

and the J7 connector of TPS929120EVM with DB-09 cable.

3.3 Firmware Update

After opening the GUI, the GUI will try to connect the EVM board. At the moment, the GUI will detect 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 10 to help user update

the firmware in the USB2ANY. Click the update button to begin the firmware update process. After

firmware update succeeds, click finish button to close the prompt window. Then the GUI will try to connect

the EVM board again with the defined device address. Once it connects successfully there will be 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 10. Firmware Update Prompt Window

If the firmware version of the USB2ANY tool is lower than 2.8.2.0 there will be not firmware update prompt

as showed in Figure 10. We have to 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. Once the explorer is opened, there will be a "USB2ANY Firmware Requirement"

prompt. Click "OK" button to continue. Follow the instructions on the "USB2ANY Firmware Loader" as

showed in Figure 11 to update the firmware.

After upgrading the USB2ANY firmware version to 2.8.2.0, close the USB2ANY Explorer and open the

TPS929120EVM GUI again. While trying to connect the EVM board, the firmware upgrade window as

showed in Figure 10 will appear.

3.4 GUI Function

This section provides instructions to run the TPS929120EVM using the TPS929120EVM 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 plug it into the PC. Other operation orders may lead to GUI working abnormally. Once it 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 should be checked. When CAN board is

not connected, left 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. You can check the connection

status on the home page where there is a green check mark on the left side of the TPS929120-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, you must 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. You can click the button to connect to hardware if hardware is not connected or to disconnect from

hardware while hardware connected.
