You can rate examples to help us improve the quality of examples. These serial-data commands have bit 7 clear, but the FTDI application note describes various other commands that are available if bit 7 is set; for example, to set an I/O pin in MPSSE mode the following commands are used: For serial output we need to set the SPI clock and MOSI pins (bits 0 & 1) to be outputs, so the command to be sent is: This makes the clock & MOSI lines into outputs,  with a value of 0. This reminds me of the Parallel port days when we used to make stuff interfaced using the PC's Parallel Port. Python SpiController.configure - 6 examples found. In this article I will try to document how to with with the FT232H using Python on FreeBSD. An earlier version of the SPI write code looked like this: Looks quite harmless, but the oscilloscope showed a major problem; see the highlighted areas on the clock trace. What use is that? PyFtdi development code is available from Like the libMPSSE-I2C and libMPSSE-SPI libraries, this library builds on the libFTDI library and provides a simpler interface for I2C and SPI protocols using the MPSSE component. An FTDI USB IC controls the FPGA. To allow use of SBCs running Python to use CircuitPython libraries to access sensors over I2C/SPI/GPIO, the Blinka library was created. I am trying to set up a communication between computer and FTDI FT2232H using python to control spi protocol in full-duplex mode. libmpsse library.
