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. Most people know of FTDI because of their popular USB UART chips, but many of those chips also have support for SPI, I2C and even JTAG. endobj please help. FTDI’s Multi-Protocol Synchronous Serial Engine (MPSSE) provides a flexible means of interfacing synchronous serial devices to a USB port. Microchip MCP2221A Also a version for SPI is available.
