All I needed to do was send the FTDI the command to toggle the pin representing the serial clock (which was also the serial clock for the SPI device), extract the status of the FTDI input pins, parse them, and repeat until the full amount of data bits were extracted. The latest PyFtdi online documentation is always available from here. "Hello World!" Drivers page. The USB bridging solutions from FTDI (i.e. So the question would be if the MPSSE can operate through arbitrary GPIO pins, or only through certain designated pins. @Lundin - the GPIOs in question are on the FT2232 chip, not the PC. As mentioned it is called mpsse, Multi-Protocol Synchronous Serial Engine to simplify synchronous serial protocol (USB to JTAG, I2C, SPI (MASTER) or bit-bang) design. Open.vi Use “Open.vi” to configure the FTDI MPSSE for SPI I2C or JTAG protocols. Just select Device ->Serial Protocol->Connection from Polymorphic drop-down menu. Hello, I try to use MPSSE-I2C lib for sending 6 bytes over i2c, modified the example they offer for eeprom. However, it is likely that bit-banging something with these would be drastically slower if that has to be explicitly done over the USB, rather than having the MPSSE do it locally and only move block data over the USB. Report. When a microwave oven stops, why are unpopped kernels very hot and popped kernels not hot? Not supported yet: I2C With the FT232H it is not possible to used I2C and SPI at the same time, because the 2 protocols use the same clock and data pins.
