Back to USB Devices TUSB5052EVM Software TUSBWINVCP Software – www.ti.com/tusbwinvcp: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 usb@ti.com.usb@ti.com –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.htmlhttp://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)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 More Information
