(when beams are blocked on only one axis, they are ignored and not reported.) the controller determines the coordinates of the touch point and reports it to the host computer. by interpolating, a ?irtual?beam between two physical beams, the number of touch points on each axis is ef- fectively doubled. when an odd number of beams along either axis is blocked, the coordinate of the center physical beam is reported. when an even number of beams is blocked, the coor- dinate of the virtual beam in the center of the blocked beams is calculated and reported. vishay dale s tip touch panels have a unique patented scan- ning and logic system that make them virtually immune to most lighting environments. the touch controller supports enter, exit, continuous, and tracking report modes or combinations of these modes. the controller also has a beeper output. hardware handshaking, soft- ware handshaking, baud rates, and x, y coordinate invert fea- tures are jumper selected. the user initializes the desired report modes, coordinates are reported automatically or upon request as needed. several optical filters are standard to provide the most cost effective filter for each application. ?on-standard?fil- ters may be specified as well. the filter increases the contrast ratio of the display and protects the display face and electronics. vishay dale can assist in recommending the optimum filter based on years of experience as a display manufacturer. the perim- eter of the filter is bonded to the bezel, and a bezel to front panel gasket is included to provide a splash proof seal. optional pc based software provides simple touch panel inte- gration (see ordering instructions). t5driver emulates a mouse in windows 95/98 applications. twdriver emulates a mouse in windows applications. tbdriver emulates a mouse in dos applications. generic drivers or drivers for other operating systems are avail- able through touch base, ltd. contact vishay dale for informa- tion.

(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. 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.
document number: 37072 revision 28-jun-01 www.vishay.com 6 TIP-5038SDE-1 vishay dale command/responsedescription (continued) sound beeper, tt = duration (00 to ff) (2ftt) this command sends a logic 0 (active state) to pin 2 of j4. the duration of the beep can be controlled in 10 msec incre- ments from 0 msec (00) to 2.55 sec (ff). note - 2c may not be used as an argument as it will cause a reset. *normal x (36) invert x (37) *normal y (38) invert y (39) the standard configuration for the touch panel places the xy origin at the lower left corner, consistent with the cartesian coordinate system. upon issuing the invert y command, the origin becomes the upper left corner, consistent with the video industry standard. these commands allow the user to move the origin to any corner to accomodate different stan- dards or third party mechanical packages which may have the touch panel rotated 180 degrees on the display. to cancel an invert x or invert y command, a normal x or normal y command must be executed. these commands may also be implemented with jumpers. placing a shunt on nor x causes x data to be normal (default), and removing the shunt causes inverted x data. similarly, placing a shunt on nor y causes y data to be normal (default), or removal causes in- verted y data. the jumper selected options may be over-rid- den with the software commands. failed beam time-out (3a t) if any ir beam is broken for an extended time due to blockage of the beam or failed optical components, the touch panel will ignore that beam after a predetermined number of scans. (this is to prevent failed beams from interfering with touch sens- ing). the actual failed beam detection time depends on the modes of operation and the size of the touch matrix. when using the continuous mode with automatic report- ing enabled, the time is typically 25-30 seconds. if the appli- cation requires longer touch times, then the time may be ex- tended using the failed beam time-out command. the command accepts arguments from 1 to f. request failed beam report (28) this command returns the address of any infrared diode/ phototransistor pair that are blocked (as when a stylus is in the panel) or have several failed scans. (the time period can be extended by using the failed beam time-out com- mand). the report uses the following format: 47 = start of failed beam report aa-nn = physical address of failed led/phototransistor pair. ff = end of report reset touch panel (2c) after issuing the reset command, the touch panel is returned to its power up condition and all operating modes are returned to their default state and the buffer cleared. request software revision number (30) request touch matrix size (33) request model number (35) these commands are provided for configuration control and diagnostic purposes. rs-232 framing or overrun error (45) an rs-232 error indicates communication problems. buffer overflow error (4f) buffer overflow occurs when the input command buffer is ex- ceeded due to lack of handshaking. initialization initialization is performed by the host computer and must be done each time the touch panel is powered up or the reset touch panel command is issued. the initialization pro- cess requires setting the desired coordinate reporting modes, enabling or disabling automatic reporting, and enabling or disabling the touch panel. default settings are shown in the commands table. when touch coordinate information is required by the host computer, the touch panel must be enabled. the flow of touch coordinates from the touch panel to the host computer can be controlled by enabling or disabling automatic reporting. with automatic reporting enabled, coordinate reports are sent to the host as soon as they become available. if the host computer is performing a task which does not require touch coordinate information, automatic reporting may be disabled. initialization/operation-example in the following example the touch panel is initialized to report coordinates only when a stylus is entered into the touch panel. the touch panel is enabled by default, and coordinate report- ing is not desired unless requested, so automatic report- ing is left disabled by default. as a result the touch panel must be continuously polled with request one coordinate report (2b) to determine if an enter point coordinate report is available. when a report is available, it will be sent to the host. if no report is available, the touch panel will send code 48 (hex) to the host.
