The cool part about this is that you can then use any of the CircuitPython Libraries that have been written for the numerous … So, for example, my idea of it would be to perhaps connect a GPIO input to the device’s output, and at each SCLK that the FTDI sends, check whether the GPIO input is high or low. Quick Example. With the help of the I2C Register library they can easily be represented and manipulated. This works just fine if you are okay with a C/C++ interface. ft prefix for all aliases is also accepted, as for example ft232h. I2C¶. LibMPSSE-SPI Examples: The Multi Protocol Synchronous Serial Engine (MPSSE) is generic hardware found in several FTDI chips that allows these chips to communicate with a synchronous serial device such an I 2 C device, an SPI device or a JTAG device. 2.1 Designer benefits I2C-bus compatible ICs allow a system design to progress rapidly directly from a functional block diagram to a prototype. Examples: ftdi://ftdi:232h:FT0FMF6V/1. You're correct about what the TCA9548A can be used for; you should be able to connect any or all of the eight channels to the master by sending the chip the appropriate command, allowing you to select between multiple devices with the same address. ftdi c example, Examples of synchronous interfaces include SPI, and I 2 C. Asynchronous means that data is transferred without support from an external clock signal . : FT_000507 Clearance No. By doing this I would be able to store these highs or lows as 1s or 0s, respectively, into a buffer. You'll need the right I2C address for your 4725 for the code fragment to work. You can rate examples to help us improve the quality of examples. serial: the serial number as a string. The latest PyFtdi online documentation is always available from here. 2.1.5 Libraries and Device Drivers The example program relies on the FTDI D2XX Device Driver and libMPSSE-I2C library.
