Clears and then displays basic text. command e.g., "DisplayText ajith vasudevan"
Control 'length' and 'position' with "DisplayText <text>, <position>, <length>"
'length' can be 1 to NUM_DIGITS, 'position' can be 0 (left-most) to NUM_DIGITS-1 (right-most)
A caret(^) symbol in the text input is dispayed as the degrees(°) symbol. This is useful for displaying Temperature!
For example, the command "DisplayText 22.5^" will display "22.5°".
DisplayTextNC text [, position {0-NUM_DIGITS-1} [,length {1 to NUM_DIGITS}]]
