COMMAND/RESPONSE DESCRIPTION
DC1, CtI Q, XON Software Handshaking (11)
DC3, CtI S, XOFF Software Handshaking (13)
RS-232 flow control is provided by these commands. Note: A
shunt must be placed on (SOFTHAND) to allow software hand-
shaking. Absence of a shunt requires hardware handshaking.
(See also ENABLE TOUCH PANEL command)
*Enable touch panel (26)
Disable touch panel (stop scanning) (27)
The touch panel must be enabled for normal operation. When
the touch panel is disabled, commands are processed as they
are received, allowing changes in modes of operation, but dis-
carding any report operations. This differs from XON/XOFF
software handshaking. When the touch panel receives an
XOFF character (13), commands are executed until the touch
panel requires transmission of a report, then all commands
received are buffered and are not executed until an XON char-
acter is received. If the buffer becomes full, the touch panel
sends XOFF.
Enable CONTINUOUS/disable TRACKING mode (24)
*Disable CONTINUOUS and TRACKING mode (25)
This coordinate reporting mode will continuously report the
coordinates of a stylus that remains in the touch panel. This
mode can be used individually or in combination with ENTER
point, or EXIT modes. The following report format is used. If
more than one stylus enters the touch panel, a non-contigu-
ous report will be generated.
41 = start of coordinate report
xx yy = binary X and Y, > = 0, X, Y = FE if non-contiguous
Enable ENTER point mode (22)
*Disable ENTER point mode (23)
This coordinate reporting mode will report the coordinates of
the point where a stylus is entered into the touch panel. This
mode can be used individually or in combination with EXIT
point, CONTINUOUS, or TRACKING modes. The following
report format is used. If more than one stylus enters the touch
panel, a non-contiguous report will be generated.
42 = start of enter report
xx yy = binary X and Y, > = 0, X, Y = FE if non-contiguous
Enable EXIT point mode (20)
*Disable EXIT point mode (21)
This coordinate reporting mode will report the coordinate of
the point where a stylus is removed from the touch panel. This
mode can be used individually or in combination with ENTER
point, CONTINUOUS, or TRACKING modes. The following
report format is used. If more than one stylus enters the touch
panel, a non-contiguous report will be generated.
Document Number: 37071
Revision 28-Jun-01
43 = start of exit report
xx yy = binary X and Y, > = 0, X, Y = FE if non-contiguous
Enable TRACKING/disable CONTINUOUS mode (34)
This coordinate reporting mode will report the coordinates of
a stylus that remains in the touch panel, but only as the stylus
changes locations. This mode can be used individually or in
combination with ENTER point, or EXIT modes. The follow-
ing report format is used. If more than one stylus enters the
touch panel, a non-contiguous report will be generated.
4E = start of coordinates report
xx yy = binary X and Y, > = 0, X, Y = FE if non-contiguous
Enable automatic reporting (29)
*Disable automatic reporting (scan but no report) (2A)
Request one coordinate report (2B)
When AUTOMATIC REPORTING is enabled, coordinate re-
ports are reported to the host as soon as they become avail-
able. After issuing the ENABLE AUTOMATIC REPORTING
command, there may be a report in the internal buffer which is
not current. If a sufficient amount of time has passed to allow
this condition, the first coordinate report returned should be
ignored.
When AUTOMATIC REPORTING is disabled, no coordinate
reports are reported unless requested with REQUEST ONE
COORDINATE REPORT. If a stylus is entered into the touch
panel after AUTOMATIC REPORTING is disabled, a coordi-
nate report will be generated and saved in an internal buffer
(depending upon coordinate reporting modes in effect) but will
not be transmitted until a REQUEST ONE COORDINATE
REPORT command is received.
If no coordinate report is available in the internal buffer, the
touch panel will return a code 48 and continue to scan until a
stylus is detected. However, no coordinate report will be re-
ported until AUTOMATIC REPORTING is enabled or the re-
port is requested with REQUEST ONE COORDINATE RE-
PORT.
Coordinate reports are reported with the following format:
Report Type = 41, 42, 43, or 4E
xx yy = binary X and Y, > = 0, X, Y = FE if non-contiguous
Enable Beeper (2D)
*Disable Beeper (2E)
Enabling the beeper sends a logic 0 (active state) to pin 2 of
J4 depending on which of the coordinate reporting modes are
enabled. If the ENTER mode is enabled, a pulse is sent for
every entry point. If the EXIT mode is enabled, a pulse is sent
for every exit point. If both modes are enabled, a pulse is sent
for every entry and exit point. CONTINUOUS and TRACK-
ING modes have no beeper outputs.
