USB-TO-GPIO2: USB-TO-GPIO to connect with multiple TPS53647EVM-710

Tool/software:

Hi guys,

I have the USB to GPIO module (2006) and it works pretty well. I can connect one device (doesn´t matter which one) without problems a 100kHz bus speed with Fusion Design.

For demonstration reasons I have 3 of the TPS53647EVM-710 next to each other and want to monitor and control all of them via one USB interface.

I followed the explanation in the manual and upgrade the IDC cable to carry 3 plugs/devices, however if I connect all of them it doesn´t work while a single one does work very well.

Probably I have overseen something that I need to change the device addresses or such but I did not find any evidence in the internet when I searched for that.

Has anybody an idea what I need to do ?

Thanks a lot

Michael
