types of touch state reports. For example, the value of 03
for the Raw Touch State Report matches the function
number of 03 for the GetRawTouchState function.
TouchReportingMode
= Reports the conditions under which TouchState reports
are sent. Legal values for the touch reporting mode
parameter are:
00 =
Solicited only. The touch system only sends the
touch state report in response to having received
the corresponding command.
01 = Parameter change. The touch system sends the
touch state report both in response to having
received the corresponding command and
whenever the touch state changes (including
coordinate changes).
02 = Continuous. The touch system sends the touch
state report both in response to having received
the corresponding command and each time that it
executes its main executive loop. This should
mean that the touch system reports the touch state
after every scan.
Note that the values for the touch reporting mode
parameter match the values for the ReportingMode
parameter in SetReportProperties (21H).
Examples
If the host sends the SetTouchModes (20H) command as follows:
66 01 20 FF
The touch system responds with the following report:
E0 05 00 20 01 01 00 FF
This report indicates no errors in Cmderr and reports the values for the
three parameters defined for the function that were in effect when the
command was sent (the
01
,
01
, and
00
values in the report). No
parameter values were changed.
If the host sends the SetTouchModes (20H) command as follows:
66 02 20 00 FF
