FTDI FT4222

[rumor]

I am trying to use an evaluation board of FTDI FT4222EV by calling the d2xx.llb and ft4222.llb functions. As a start, I am able to set and read the clock setting, which I think means the communication is ok. But when I call the "SPI Master Init" function and try to change the clock polarity, the output of the CLK pin is always low even I set "CLK_IDLE_HIGH", and the function status return is "OK". Please give me some idea about what could be missed.

Thank you.

Hi rumor,

both the board and the library are provided by a 3rd party so I doubt anyone here will be able to help you without seeing the code.

Please at least post screenshots, so that we can see what is happening.
