Hi Li,

This is an issue related to the FTDI drivers and not with the EVM or GUI tool. We have included other versions of the FTDI driver that you can try to install and see if they work on your PC. They are included in the GUI directory in your program files.

If this does not help resolve your issue, I would suggest using an Aardvark USB to I2C/SPI adapter instead.

Thank you,
Eric

Hi Li,

the correct FTDI driver version is different from PC to PC. I would suggest trying the others included in the tool directory. The Total Phase Aardvark can be purchased through the Total Phase website.

Thank you,
Eric
