Chapter 5 - Smart-Frame Protocol II CARROLL TOUCH
5-20 Touch System Programmer’s Guide
Report Transfer
The method of transferring reports differs slightly between SFP and
SFP-II. In SFP, turning Report Transfer off disables all reports, both
solicited and unsolicited. In SFP-II, setting the ReportTransferMode
parameter to disabled inhibits unsolicited reports but does not inhibit
solicited reports.
In the SFP, the Report Transfer parameter is enabled and disabled via
the Report_Transfer_On (44H) and Report_Transfer_Off (43H) SFP
commands and is reported in the Report Transfer parameter of the
Get_State_Report (47H) SFP command.
In SFP-II, the ReportTransferMode parameter is set and reported via
the ReportTransferMode parameter of the SetTouchModes (20H)
SFP-II function.
If Report Transfer is disabled when the touch system is switched to
SFP-II, any SFP reports that are pending at that time are sent before
the SFP-II Protocol Version Report is sent. The Report Transfer
parameter remains set to disabled.
Note
The Report Transfer shared parameter is implemented in the GW
DSP Serial Controller in a different manner from that described
here because the SetReportTransferMode (22H) SFP-II function is
not implemented on this controller. The ReportTransfer parameter
is shared as described, but when the controller is switched from
SFP mode to SFP-II mode, the ReportTransfer shared parameter is
set to enabled. When the controller is switched from SFP-II back
to SFP, the ReportTransfer shared parameter does not change
value.
