TABLE 3-2:
As seen in Table 3-2 above, the AR1100 Touch Screen Controller Board provides flex-
ibility to the ‘Button 1’ field in the HID-MOUSE touch report. The value of ‘Button 1’ and
the touch reports issued in reaction to touch events is dictated by the operational
parameter, TouchMode, (described in the AR1100 Resistive USB and RS-232 Touch
Screen Controller data sheet, DS41606). In the summary below, touch report field “P”
(pen) corresponds to ‘Button 1’.
3.3.2.1
In reaction to each touch state/event, the AR1100 issues 0,1,2 or 3 touch reports with
