There is a function in the api called
ftdi_set_baudrate(ftdi_context,baudrate)
I am not sure if it is as simple as calling this function with a 3000000 for 3MHz or if there is some other calculation involved.
Does ftdi_set_baudrate(ftdi_context,3000000) == 3MHz MPSSE SPI mode?
I am trying to sample a 1.5 MHz signal on the "Data Input (DI)" pin of both channels(A & B).
Thanks

Hello,
I am a beginner to using FTDI chips and want to use FT4232H for sampling a 1.5 MHz line. I am hoping that if I could run MPSSE SPI at a baud rate of > 3Mhz or 6 Mhz, will give me a reliable sample.
I am struggling to understand how the baud rate interacts with MPSSE. I have been through the examples in the libftdi source and the mailing list, but am not having much luck. Any documentation that I can find on baudrate seems to be correlated with BitBang mode or UART mode.
Can anyone please guide me to where I can find more information on how the baudrate interacts with MPSSE SPI?
Thanks
Siva
