The FTDI Driver API for Serial is a software add-on for LabVIEW. This add-on provides high-level building blocks to communicate with the Future Technology Devices International (FTDI) MPSSE based on the D2XX driver. The MPSSE provides a flexible means of interfacing synchronous serial devices to a USB port. You can use the FTDI Driver API for Serial to write applications and communicate with the FTDI Chip�s I�C/SPI devices without low-level D2XX driver knowledge. The add-on supports serial MPSSE data rates of up to 30 Mb/s on SPI and I�C.
