Multi-Protocol Synchronous Serial Engine (MPSSE) - Some FTDI chips support MPSSE, which can send SPI (or I2C or other) protocols without you having to worry about bit-banging pins. It has been tested with Windows 7 64 bit and 32 bit. is supposed to be used together with the FT232H interface driver for FPGA configuration in drivers/usb/misc/ft232h-intf.c which adds an mpsse spi platform device describing USB SPI bus with DESCRIPTION. + struct platform_device *pdev = priv->pdev; + /* Setup and send off the Hi-Speed specific commands for the FTx232H */, + priv->xfer_buf[0] = DIS_DIV_5; /* Use 60MHz master clock */, + priv->xfer_buf[1] = DIS_ADAPTIVE; /* Turn off adaptive clocking */, + priv->xfer_buf[2] = DIS_3_PHASE; /* Disable three-phase clocking */.
