Updating the PixyCAM’s Firmware

When it comes to upgrading your PixyCAM to the latest Firmware is idiot proof. The PixyCam uses a ROM-based algorithm to upload new firmware into flash memory over USB, which makes Pixy “unbrickable” – that is, you will always be able to recover the PixyCAM from an unsuccessful firmware upload or a “bad” version of firmware.

The First Time You Upload Firmware

Before you start, make sure of the following:

  1. PixyMon is running on your computer & the PixyCAM is NOT Connected.
  2. You have your new firmware file available somewhere on your computer. You can find the latest version here.

Now do these steps (please):

  1. Make sure PixyCAM is NOT plugged in to a USB cable.
  2. If you haven’t already, connect a USB cable to your computer
    plug in usb cable
  3. Press and hold down the white button on top of PixyCAM. While holding the button down, connect PixyCAM to the USB cable from the previous step. Once the cable is connected, you can let go of the button.


Holding the white button down while connecting PixyCAM to USB puts Pixy in “firmware upload mode”. Since this is the first time you have uploaded firmware onto PixyCAM, your computer will go through a driver installation process. This is because Pixy uses a separate device driver for firmware upload, and your computer hasn’t seen this device on its USB port before.

Note: this only happens if you’re using a Windows computer. If you’re using a Mac or Linux machine, scroll down to the “Pixymon” section and skip this driver installation business.

Windows Vista, 7, 8 or 10

You should see a balloon message pop-up in the system tray similar to this one:


Wait for the new PixyCAM USB Driver to finish installing, which shouldn’t require any actions on your part, just some waiting.


In the PixyMon command/status window (at the bottom of the PixyMon window) you should see the message “Pixy programming state detected“. If you don’t see this message, the drivers may still be installing. Just be patient.


The file selection dialog will appear. Browse to where you saved the new firmware file (.hex) and select it, then press OK.


The PixyCAM will then take the new Firmware file and write it into its flash memory in only takes 2 or 3 seconds. When the upgrade is done, you should see the “done!” message in the PixyMon command/status window, and the new firmware will start running on your PixyCAM.


You’re done! Now wasn’t that easy, the PixyCAM now has the latest Firmware installed and is ready to use..


Next Time You Upload Firmware

The next time you upgrade the PixyCAM’s firmware, the drivers will be installed, so you just need to initiate firmware upload mode by holding down the white button, while plugging in the USB cable.
