Step 1. Download the uf2 file here. DO NOT try to open it. It’s for later.
Step 2. On the PICO, there is a button labelled BOOTSEL. Hold this button down WHILE plugging the pico into your computer.
Step 3. A device should come up on your computer called RPI-RPI. You need to drag and drop the openmind.uf2 file you downloaded earlier onto this device.
Step 4. The device will do some loading, then disappear and come back as a CIRCUITPY device.
Step 5. Your device is now set up with the firmware, libraries and example code needed to start tinkering. The touch sensors are currently setup to be midi signals Head here to test out the MIDI functions.
Step 6. If you’ve added the LED hat, you’re probably getting blinded each time you touch a sensor. Open up the file on the circuitpy device that says code.py in Notepad or any other basic text editor. Scroll down until you find a chunk of code that looks like this:
The value after pixels.brightness controls the brightness of the LEDs. It goes from 0 to 1, so 0.1 would be 10% brightness. Turn it down to 0.05 and hit save.
