super witchy eurorack LFO Module based on SAMD21/ Xiao
If you are interested in modifying the code, you will first need to download the latest version of Arduino IDE which can be found here:
https://www.arduino.cc/en/software
Now, follow these instructions so that Arduino can recognize our board, the Seeeduino XIAO.
https://wiki.seeedstudio.com/Seeeduino-XIAO/
Next, we need to install an additional library so that your code will compile. This library can be downloaded directly from inside the Arduino IDE by going to Tools> Manage Libraries...
Once the Library Manager opens you can use the search bar located at the top to find the library we will need to install. Using the search bar, type in “FlashStorage_SAMD” and install the latest version. Note that this code was written with version 1.3.2 of the FlashStorage_SAMD library.
Select the Xiao Board: Tools -> Board -> Seeed SAMD -> Seeeduino Xiao
Once you have the Arduino IDE installed and recognizing your XIAO and have installed the “FlashStorage_SAMD” library, you are now ready to compile the code and modify it until your heart and ears are content.

Update can be done by dragging the UF2 file onto the boot disk. The boot disk appears by:
Connecting the Xiao to USB, Do not connect Eurorack Power at the same time
Double tap the reset pin pair with tweezers
Confirm that an "Arduino" Folder appears in Finder/Explorer.
Drag the UF2 file to the root disk directory.
