CircuitPython is a derivative of MicroPython designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the CIRCUITPY drive to iterate.
Follow this quick step-by-step for super-fast Python power :)
If you want to get started with your QT Py, and you have NOT soldered a chip to the back of it, download CircuitPython from the following link:
Click the link above and download the latest UF2 file.
Download and save it to your desktop (or wherever is handy).
Plug your QT Py into your computer using a known-good USB cable.
A lot of people end up using charge-only USB cables and it is very frustrating! So make sure you have a USB cable you know is good for data sync.
Double-click the small RST (reset) button, and you will see the NeoPixel RGB LED turn green. If it turns red, check the USB cable, try another USB port, etc.
If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!
You will see a new disk drive appear called QTPY_BOOT.
Drag the adafruit_circuitpython_etc.uf2 file to QTPY_BOOT
