3.4 GUI Function
This section provides instructions to run the TPS929240EVM using the TPS929240EVM 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 TPS929240-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 TPS929240-Q1 12-Channel Automotive 40-V High-Side LED Driver with FlexWire data sheet

Modifying the EEPROM registers' value on the register map page does not overwrite the real EEPROM
registers' value. Real EEPROM registers' value can be modified only through EEPROM programming page.
Jumping to other pages from the programming page or clicking "Exit PROG mode" button automatically forces
the device exit EEPROM programming mode through clearing CONF_STAYINEEP method, which means the
newly modified EEPROM registers value do not update to corresponding configuration registers after exiting
EEPROM programming mode. CLR_REG can be set through register map page to update configuration
registers with the latest EEPROM registers value immediately. For other detailed operation instructions, see
the walkthrough wizard of this page.

STANDARD TERMS FOR EVALUATION MODULES
1. Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or
documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance
with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
WARNING
Evaluation Kits are intended solely for use by technically qualified,
professional electronics experts who are familiar with the dangers
and application risks associated with handling electrical mechanical
components, systems, and subsystems.
User shall operate the Evaluation Kit within TI’s recommended
guidelines and any applicable legal or environmental requirements
as well as reasonable and customary safeguards. Failure to set up
and/or operate the Evaluation Kit within TI’s recommended
guidelines may result in personal injury or death or property
damage. Proper set up entails following TI’s instructions for
electrical ratings of interface circuits such as input, output and
electrical loads.
NOTE:
EXPOSURE TO ELECTROSTATIC DISCHARGE (ESD) MAY CAUSE DEGREDATION OR FAILURE OF THE EVALUATION
KIT; TI RECOMMENDS STORAGE OF THE EVALUATION KIT IN A PROTECTIVE ESD BAG.
