Other Parts Discussed in Thread: ADS5545


I want to use the TI_ADC_SPI_5p1 software together with my own PCB. A FTDI chip is there like on the ADS528x EVM. Which VID, PID and other data must be entered in the EEPROM of the USB device, to achieve that the device is recognized as a supported device?



  • Hi,

    Attached please find the ept file template that is used when we program the FTDI device on our EVMs.  That will provide the VID and PID, and anything else that you might find you need later to make your board work with the TI ADC SPI 5p1 GUI.  The file name still lists ADS5545 because that was the first EVM to use the FTDI device, and we hadn't had to make another template until we moved from the 245BM device to the 245RL device for some EVMs.


    USB VID=0403

    USB PID=C5A8

    Note that the TI ADC SPI 5p1 GUI expects to find the three SPI lines on a certain three pins of the 8 bit bus out of the FTDI device, and if you choose different pins from the FTDI device for SCLK, SDATA and SEN than the EVM used, then the SPI GUI will not work.  Note that we put SCLK on bit D0, SDATA on D1, and SEN on D2.  We routed D3 and D4 to the reset and powerdown pins, but the SPI GUI does not drive them so they are unused.

    Besides these two numbers, i believe it is important to keep the text string:

    Product=USB ADC Interface

  • Hi,

    Thanks a lot for the quick and detailed reply. It works fine now.

    Best regards
