Other Parts Discussed in Thread: MSP430F5438, TUSB3410

i hav connected the same circuit as in the uartpdk evm and then programmed the eeprom with the tusb3410 eeprom burner utility with the same vid pid as the evm i.e. VID_0451&PID_341A  now after programming the eeprom when i connect it to windows 7 32 bit using hyperterminal it says that "unable to open com port . please check settings" and the device disconnects and connects itself to usb again . i hav used the default driver for vcp provided in swrc094f . also on windows xp 32bit and still having the same problem and even on windows 7 64bit . i need to connect it to msp430f5438 for basic uart communication 

please help

    Karanpreet Singh,

    Please change the TUSB3410 port number to a lower port (COM3). Please go to device manger ->TUSB3410 UART EVM(COM13) -> properties ->port settings -> COM port number -> change to a lower number . Now unplug and connect again the TUSB3410 EVM board from the PC, now the device manager will show you the TUSB3410 EVM board with the new COM port number, you can try again with the HyperTerminal.

     

    Best regards,

    Roberto.

    Roberto Diaz,

    thanks for the help now its working, actually there were two problems one was the com. no and the other was that at the 1.8v input i was not getting 1.8v rather i was getting around 1.2 volts due to wrong resistor value. so now after changing that its working.

    Hi to all,

    I am using TUSB4130 USB-COM cable to open hyper terminal to communicate with some device. The hyper terminal is opening but it is failing to send the commands to the device. And rest of the hardware is working properly. I also used PL2303 USB-COM cable. The device is responding properly with PL2303. Was der any difference bteween these two? i.e., TUSB4130 and PL2303... and is der any hardware r software changes required for making TUSB4130 to work properly?  Please suggest me...

    Thank you,
