WipperSnapper is a different application from CircuitPython. Because of this, installing WipperSnapper will completely erase the CircuitPython installation and all files on your board.
If you did not install CircuitPython on this board, you may ignore this step and proceed to the next step.
Verify and Backup CircuitPython Installation
When you plug a CircuitPython board into your computer, your computer will see the board's flash memory as a USB flash drive where files can be stored. When the board is running CircuitPython, you'll see the CIRCUITPY drive.
If you see the CIRCUITPY drive appear as a USB flash drive:
- Copy all files to a safe location on your computer, like your desktop.
Code.pyis the most important file on this drive as it contains your CircuitPython code.
If you do not see the CIRCUITPY drive and instead see a drive named boardnameBOOT (such as one of these drive names):
- Locate the reset button on your board. It's a small, black button, and on most of the boards, it will be the only button available. It is typically labeled RESET or RST on the board.
- Tap this button once
- If the drive changes from boardnameBOOT to CIRCUITPY, follow the instructions above to back up its contents
- If it stays as boardnameBOOT, the board does not have CircuitPython installed. You may proceed to the next step.
Once you've backed up your CIRCUITPY drive, proceed to the next steps to download and install the WipperSnapper firmware.
