LibMPSSE-SPI(Recommended) FTDI have provided a new library to configure the MPSSE for emulating SPI.

FTDI Chip 2-channel (FT2233HP) and 4-channel (FT4233HP) versions are the Hi-Speed (480Mbits/s) devices have serial UART (RS232, RS422 or RS485) and MPSSE (JTAG, I2C, SPI or Bit-Bang) interfacing capabilities. endobj + dev_err(dev, "Missing platform data.\n"); + !pd->ops->read_data || !pd->ops->write_data ||, + !pd->ops->lock || !pd->ops->unlock ||, + !pd->ops->set_bitmode || !pd->ops->set_baudrate ||, + !pd->ops->disable_bitbang || !pd->ops->cfg_bus_pins), + if (pd->spi_info_len > FTDI_MPSSE_GPIOS), + /* Find max.

The MPSSE can be placed in loop-back mode for diagnostic purposes (data transmitted out of the DO pin, is also internally connected to the DI pin). MPSSE is beside bit-bang-mode by far the most interesting feature of those FT2232/4232, but I could not find a single example using that mode beside the examples from FTDI … Amazing IC with a lot more capability for a fraction of the price. + dev_dbg(dev, "Waiting data ready, read: %d\n", ret); + print_hex_dump_debug("RD: ", DUMP_PREFIX_OFFSET, 16, 1. In a synchronous protocol (such as SPI or I2C) both clock and data signals are transmitted from sender to receiver, so the two remain in sync. Introduction. : BRT_000005 Clearance No. These libraries build on top of the D2XX driver above and provide a simpler interface to I2C and SPI communication with the FT232H's MPSSE component.

Using the FTDI FT232H chip this breakout provides a USB to serial UART with a special 'Multi-Protocol Synchronous Serial Engine' (MPSSE) that can talk many serial protocols such as SPI, I2C, serial UART, JTAG, and more! FTDI’s Multi-Protocol Synchronous Serial Engine (MPSSE) provides a flexible means of interfacing synchronous serial devices to a USB port. If the protocol is SPI, I2C, JTAG or Serial Port then you should use the native mode supported by the FT232H.
