FIRMWARE VERSION
The format of the firmware version number is of the form 1.2, comprising a single digit
integer part and a single digit fractional part. When first powered up, the controller
displays the version number by flashing the integer digit value in red and the fractional
digit value in green. To determine the version number, count the number of red flashes
and then the number of green flashes immediately after power-up. For example, a
single flash of red followed by a single flash of green indicates a version number of 1.1.
