command number. The parameters 02 and 12 represent the
ProtocolVersionHi and ProtocolVersionLo bits, indicating protocol
version 2.12.
Reporting Modes
Each SFP-II report has a reporting mode associated with it that
specifies when the report is to be sent. The available reporting modes
are:
Solicited Only Mode - The touch system sends the selected
report after receiving the corresponding
command.
Parameter Change Mode- The touch system sends the selected
report after receiving the corresponding
command and whenever any of the
parameters contained in the report
changes.
Continuous Mode - The touch system sends the selected
report after receiving the corresponding
command and each time that it executes
its main executive loop.
Parameter Change Mode and Continuous Mode produce “unsolicited
reports,” because reports are sent by the touch system even though it
has not received a corresponding SFP-II command. The default
reporting mode of most reports is Parameter Change Mode. The
exceptions to this are the Multi Touch State and Raw Touch State
Reports, which are solicited only.
Use the SetReportProperties (21H) function to set the reporting mode
of reports.
Report Transfer Mode
When report transfer is disabled, unsolicited reports are not transferred
from the touch system to the host. Solicited reports continue to be
transferred from the touch system to the host.
When report transfer is enabled, both solicited and unsolicited reports
are transferred.
Use the SetReportTransferMode (22H) function to set the reporting
mode of reports.
