5. TUSB3410UARTPDK Software TUSBWINVCP Software – www.ti.com/tusbwinvcp:
Win98, WinMe, Win2K, and WinXP Drivers and Firmware object code that creates a Virtual COM Port (VCP) can be downloaded from the above tool folder link if you agree to the online license agreement that requires registration with MY.TI.
Linux has native support in kernel tree. Other Linux support can be found at or by contacting
MAC is in development with BETA versions available by contacting
To create your own application firmware, a compiler will be necessary:
The TUSB3410 is based upon the industry-standard 8052 microcontroller for which there are several compilers on the market that would be suitable. Some examples are at and at
The source code for our VCP drivers is available after an on–line survey is submitted and reviewed at
Utilities:
USB I2C Header Generator Utility for VCP Applications Utility (www-s.ti.com/sc/psheets/sllc251/sllc251.zip)
A DOS-based tool that generates an image file for your I2C EEPROM using your binary object code and/or custom descriptors as inputs.
Note: AppLoader should not be used in conjunction with this tool

7. TUSB3410GPIOPDK Software Firmware: Drivers: Utilities:
The EVM board comes with firmware that makes the PDK act like a four-key USB keyboard.
Source code for this sample code is available to download after registering through MY.TI
To create your own FW, a compiler will be necessary. There are several compilers on the market that would be suitable, for example, see and
Drivers:
The PDK assumes usage of the USB Human Interface Device (HID) class driver. For more information on class drivers, refer to the USB Implementers Forum website at
If this driver will not be acceptable for the given application, a custom driver will need to be written. One option is to use a package like the Jungo WinDriver ( Package. Another option would be to use the Microsoft DDK USB Driver.
Utilities:
I2C Header Generator Utility (www-s.ti.com/sc/psheets/sllc152d/sllc152d.zip):
DOS-based tool that generates an image file for your I2C EEPROM using your binary object code as input.
AppLoader Driver (www-s.ti.com/sc/psheets/sllc160/sllc160.zip):
Windows USB device driver that enables firmware to be kept on the PC rather than in the USB device's EEPROM during the FW development process
Note: AppLoader should not be used in conjunction with the TUSB3410UARTPDK
