Chapter 3: Guidelines for Writing a Software Driver
A computer must have a driver in order for the Bit Pad Two to be connected. The driver is
a software subroutine that collets and decodes Bit Pad Two reports for use by another
(master) program. This section provides some guidelines, in the form of flowcharts, for
writing a driver.
The flowcharts are for a Bit Pad Two using the packed binary report format. The steps are
general for any set of operating characteristics.
NOTE: In the context of these charts, normalize means to combine the two coordinate
bytes into the format required by your master program.
