SPOKE-mini

SPOKE-mini is a minimal PCB design that allows you to turn a Raspberry Pi Pico into a 26-pin capacitive touch sensor board.

It comes as a DIY-SOLDER-YOURSELF kit, with 26 1M Ohm resistors and a Raspberry Pi Pico.

This board is perfect for embedding inside projects for a more permanent touch based solution.

Assembling the Pico is as simple as soldering the resistors into the correspongind areas marked R1, R2, R3 etc. Soldering a rpi pico into the middle of the board and then flashing the Circuitpython uf2 file and example code.

Firmware + Code

Spoke MINI firmware instructions:

Step 1. Download the most recent Circuitpython uf2 file from here: https://circuitpython.org/board/raspberry_pi_pico/

Step 2. Hold down the Bootsel button on the Pico while plugging in the USB cable.

Step 3. Drag and drop the Circuitpython uf2 file onto the Rpi device.

Step 4. Wait for the firmware to flash onto the device, it will dissappear for a second and come back as a CIRCUITPY device.

Step 5. Download the Libraries Bundle .zip file here: https://circuitpython.org/libraries

Step 6. Find the libraries for Adafruit_MIDI and drag it from the zip file into the CIRCUITPY device into the folder called 'lib'

Step 7. Open the code.py file on the Circuitpy device either in an IDE like Thonny, or in Notepad if you're just starting out.

Step 8. Copy and Paste the example code here: https://github.com/Tom-Vulpes/Spoke/blob/main/SPOKE-mini/MIDI%20examples/MIDI-USB%20-%20single%20notes%20-%20polyphony and save it as code.py. Make sure you don't save it as any other file name, the device runs whatever is in code.py on startup.
