Note • A shunt must be placed on (softhand) to allow software handshaking. Absence of a shunt requires hardware handshaking. (See also enable touch panel command) Enable touch panel (1) (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 discarding 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 character is received. If the buffer becomes full, the touch panel sends XOFF. Enable continuous/disable tracking mode (24) Disable continuous and tracking mode (1) (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-contiguous 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 (1) (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 (1) (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 following 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) (1) (2A) Request one coordinate report (2B) When automatic reporting is enabled, coordinate reports are reported to the host as soon as they become available. 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 coordinate 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 reported until automatic reporting is enabled or the report is requested with request one coordinate report. 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 (1) (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 tracking modes have no beeper outputs. 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 ms increments from 0 ms (00) to 2.55 s (FF). Note • 2C may not be used as an argument as it will cause a reset. |
