Tusb5052evm software
TUSB5052EVM 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.

    • MAC and Linux support is in development with BETA versions available by contacting [email protected]

    • 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 www.iar.com, www.keil.com, and at www.tasking.com.

      • The source code for our VCP drivers is available after an on–line survey is submitted and reviewed at http://focus.ti.com/docs/toolsw/folders/print/tusbwinvcp-srccode.html

  • 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
