Appendix B - Smart-Frame Protocol II Function Reference CARROLL TOUCH
B-22 Touch System Programmer’s Guide
If the host subsequently sets the reporting mode of the function to
Parameter Change Mode and the screen is touched, the touch system
sends TouchState reports similar to the following to report the
movements of the stylus within the active area of the touch screen:
E0 09 00 01 01 00 0C 07 D3 00 00 FF
E0 09 00 01 01 00 0D 07 D2 00 00 FF
E0 09 00 01 00 00 0D 07 D2 00 00 FF
If the host then sends the GetProtocolVersion (65H) command as
follows:
66 01 65 FF
The touch system responds with a Protocol Version Report similar to
the following:
E0 04 00 65 01 15 FF
If the host then sends the SetReportTransferMode (22H) command as
follows to set the state of the ReportTransferMode SFP-II global
parameter to disabled and inhibits unsolicited reports:
66 02 22 00 FF
The touch system responds with a Report Transfer Mode Report to
indicate the new state of the ReportTransferMode parameter:
E0 03 00 22 00 FF
If the screen is touched again, the touch system does not send any
Touch State Reports because all unsolicited reports have been inhibited
due to the fact that the ReportTransferMode global parameter is set to
disabled.
However, if the host sends a GetTouchState (01H) command, the touch
system responds with a Touch State Report similar to the following to
report the current touch state:
E0 09 00 01 00 00 0D 07 D2 00 00 FF
The Touch State Report is sent even though the ReportTransferMode
global parameter is set to disabled because it is a solicited report; that
is, it was generated in response to a corresponding SFP-II command.
