=====Twiddler 3 Firmware=====

Click [[firmwareupgrade|here]] for detailed upgrade instructions.

  * Identify which firmware you are running by opening a notepad on the host device and pressing [[specialchords|N+S 0R00]] on the Twiddler. \\ \\
  * All Twiddlers come factory installed with a firmware version ending in "**b**", for "Base", e.g. 0.07**b**. \\ \\ 
  * All in-field upgrade firmware is designated with a "**u**", for "Upgrade", suffix instead, e.g. 0.09**u**. \\ \\
  * Only changes in the //numbers// of a firmware name indicate differences in the firmware, so 0.09**b** and 0.09**u** are functionally the same.  \\ \\
  * Upgrading from 0.07 to 0.09 will show a firmware version of 0.09u afterwards to indicate that you have upgraded from 0.07b.
