Sometimes, when a Phidget has a new hardware revision (e.g. 1018_2 -> 1018_3), the firmware version's hundreds digit will change because entirely new firmware was needed (usually because a change in the processor). In this case, older hardware revisions won't be able to be upgraded to the higher version number and instead continue to get bug fixes within the same major revision.

'''Firmware Upgrade'''

MacOS users can upgrade device firmware by double-clicking the device row in the [[Phidget Control Panel]].

Linux users can upgrade via the [{{SERVER}}/downloads/phidget22/tools/linux/phidget22admin.tar.gz phidget22admin] tool (see included readme for instructions).

Windows users can upgrade the firmware for this device using the [[Phidget Control Panel]] as shown below.

'''Firmware Downgrade'''

Firmware upgrades include important bug fixes and performance improvements, but there are some situations where you may want to revert to an old version of the firmware (for instance, when an application you're using is compiled using an older version of phidget22 that doesn't recognize the new firmware).

MacOS and Linux users can downgrade using the [{{SERVER}}/downloads/phidget22/tools/linux/phidget22admin.tar.gz phidget22admin] tool in the terminal (see included readme for instructions).

Windows users can downgrade directly from the Phidget Control Panel if they have [{{SERVER}}/downloads/phidget22/libraries/windows/ driver] version 1.9.20220112 or newer:

'''Firmware Version Numbering Schema'''

Phidgets device firmware is represented by a 3-digit number. For firmware patch notes, see the device history section on the ''Specifications'' tab on your device's product page.

* If the digit in the 'ones' spot changes, it means there have been bug fixes or optimizations. Sometimes these changes can drastically improve the performance of the device, so you should still upgrade whenever possible. These upgrades are backwards compatible, meaning you can still use this Phidget on a computer that has Phidget22 drivers from before this firmware upgrade was released.

* If the digit in the 'tens' spot changes, it means some features were added (e.g. new API commands or events). These upgrades are also backwards compatible, in the sense that computers running old Phidget22 drivers will still be able to use the device, but they will not be able to use any of the new features this version added.

* If the digit in the 'hundreds' spot changes, it means a major change has occurred (e.g. a complete rewrite of the firmware or moving to a new architecture). These changes are '''not''' backwards compatible, so if you try to use the upgraded board on a computer with old Phidget22 drivers, it will show up as unsupported in the Control Panel and any applications build using the old libraries won't recognize it either.
