This is assuming the use of the FT232H USB<–>Serial converter.

All that should be needed to develop is running bootstrap.bat.

That should have the necessary modules and Enlighten.py has the environment variable setting, i.e.:

C:> set BLINKA_FT232H="1"

libusbK Driver Setup via Zadig (Windows-only)

If there are any issues connecting though, this tutorial should resolve them:

https://learn.adafruit.com/circuitpython-on-any-computer-with-ft232h

While setting up an installed version of ENLIGHTEN 3.x on a new Windows computer, Zadig was still required to replace the driver as in the linked tutorial. If the driver wasn't libusbk then Enlighten wouldn't see the FT232 board.

Typical sequence:

download Zadig from https://zadig.akeo.ie/
run Zadig
Options -> List all Devices
Pull-down the main combo box and select "USB Serial Converter"
Select driver "libusbK"
Click "Replace Driver"

Troubleshooting

Environment Variables

$ export BLINKA_FT232H=1

Missing backend

MacOS: $ export DYLD_LIBRARY_PATH=/usr/local/lib

Environment Variables

Wasatch.PY (specifically, SPIDevice.py) contains default assumptions about how your Adafruit FT232H is wired into the 15-pin Accessory Connector, as well as the baud rate and USB block-size for communicating with the FT232H.

You can override those defaults by setting environment variables before running ENLIGHTEN. See here for more information:
