The string buffer used during programming is 80 char-
acters in length with one character reserved for the car-
riage return (CR). As such, if more than 79 characters
are typed before a CR is detected, the Twiddler2 will
discard the data and display the
BUFFER OVER-
FLOW
message.
It is important to understand that the characters being
stored are only the ones typed by the Twiddler2 itself.
If a second keyboard is in use, characters typed on this
keyboard are never seen by the Twiddler2 and are not
stored in the buffer. In other words, the text editor is
only for visual feedback, it does not actually provide the
data input.
When saving the key map, only the last entry for a
chord is actually stored. As such, if a chord definition is
entered incorrectly, but accepted by the Twiddler2, the
user needs only to re-enter it correctly.
2.2.1 Predefined Keys
Predefined keys have their scan codes defined in the
internal program memory of the Twiddler2, and should
be used whenever possible as they require the least
amount of custom key memory. The following prede-
fined keys exist in the Twiddler2.
