clock

Hello,

I'm trying to write/read to an extern device connected to a FTDIchip FT2232 MPSSE mode using SPI. I'm using the SPI function given by FTDI for Labview. I'm doing this:

Open_Device - Init_Device - Write/Read - Close_Device

The problem is that I don't have a clock signal on the scope when I try to read/write.

Do you have a solution?

Thanks
