Plug your SPOKE into your computer with a data-capable USB cable. It should appear as a drive called CIRCUITPY in your file explorer.

Click Open code.py above. Navigate to the CIRCUITPY drive and select code.py. This tool needs access to write back to it later.

Click Upload diagnostic. This temporarily replaces your code.py with test code that streams live sensor data. The board will restart automatically.

Click Connect serial and select your SPOKE from the port list. The sensor bars will come to life — you'll see the orange bars move and threshold markers appear.

Touch each pad on your SPOKE. The bar for that sensor will turn green when it triggers. If it doesn't trigger, the threshold marker may be set too low.

Drag the orange marker on any bar left or right to change the trigger threshold for that pad. Lower = more sensitive. Higher = less sensitive. Touch the pad to test it.

When you're happy, click Download thresholds. A preview of your updated code.py will appear. Click Save to device to write it directly to your SPOKE — done!

Use Reset thresholds to clear all markers back to blank. The board auto-calibrates on each restart, so thresholds may shift slightly between sessions.
