See the installation instructions for more detailed requirements, but hopefully things will work by just running the following:
$ pip install pylibftdi
Connect and enumerate FTDI devices¶
Connect the FTDI device to a free USB port. Run the
to enumerate connected FTDI devices:
$ python -m pylibftdi.examples.list_devices
For each connected device, this will show manufacturer, model identifier, and serial number. With a single device connected, the output maybe something like the following:
Though hopefully with a different serial number, or else you’ve either stolen mine, or you are me…
Test some actual IO¶
Connect an LED between D0 of your bit-bang capable device and ground, via a 330 - 1K ohm resistor as appropriate.
Test the installation and functioning of pylibftdi with the following:
$ python -m pylibftdi.examples.led_flash
The LED should now flash at approximately 1Hz.
To test some input, remove any connections from the port lines initially, then run the following, which reads and prints the status of the input lines regularly:
$ python -m pylibftdi.examples.pin_read
pin_read example is a complete command line application which can
be used to monitor for particular values on the attached device pins, and
output an appropriate error code on match. Repeat the above with a trailing
--help for info.
