TSW3003EVM USB Control

Other Parts Discussed in Thread: TSW3003

Hello,

 

I have 2 TSW3003EVM boards that I am using in a system. I am using TI's provided software to program the two boards via USB, however, when I have both boards connected to the same PC, I am only able to program one of the boards and not the other. Is there any solution for this? Also, can you provide the source code for the programming interface of these boards?

Thanks,
Neema

    Neema,

    The TSW3003 software was never designed to handle multiple TSW3003 on the same computer.  We have never tried to do this and I would expect this not to work as the USB enumeration was not designed to handle multiple instances of this board - the software just sees one of the boards at a time.  The only solution would be to use 2 different computers.

    The GUI is programmed in labview.  In general we do not provide the source code for this as we do not have the resources to support the code.  The USB interface is done using an FTDI FT245RL operating in a serial to parallel mode and we bit bang the LE, CLK and DATA bits to enable the SPI.  If you want to create your own interface you may want to contact FTDI for driver information.

    Regards,

    Ken.
