The USB-MPSSE cable is capable of
providing a USB to SPI, I2C or JTAG interface. This is
accomplished by the MPSSE within the FT232H device which has the ability to
emulate synchronous serial protocols while handling all the USB
signalling and protocols.
To expedite application development, FTDI has provided libraries which handle the MPSSE commands to emulate several
NOTE: use of the MPSSE libraries
requires that FTDI's D2XX drivers are installed.
The following application notes show practical examples of using the new USB-MPSSE cables to interface to SPI and I2C busses. These provide full explanation and source code examples of how to configure the MPSSE of the new cables.
