Returns the current calcommp extents, or counts per axis in 2 mil increments. HPI to CPU data flows are synchronized by a flip-flop with preset and clear which records the state of the HPI output buffers as to whether data has been written and read.
The firmware description includes block flowcharts of computer instructions for combining the Interface and microprocessor circuit and the application example demonstrates their use in creating a template menuing system. A method implemented by a first computer program running on a computer for executing a control command from a second program running on the computer directed to any one of a plurality of regions of a digitizer, comprising:. The complete listing of the example device's attributes, defined tablet coordinate system and each region can be found aclcomp Listing 1 below.
Once the tablet coordinate has been translated into the region's coordinate calcompp, the events for the digitizer report are updated to reflect whether the coordinate has changed from the prior report.
Method and caldomp for issuing transaction requests to a target device in accordance with the state of connection between the portable computer and the target device.

Once this is accomplished, the list of regions whose bounds intersect this area are then calcimp sequentially to determine if the tablet coordinate lies within each region. Using outdated or corrupt Calcomp drivers can cause system errors, crashes, and cause your computer or hardware to fail.
Finally, event packets are generated by the Interface in response to user-actions such as button presses, button releases or movement of the cursor within a specific region.
In order to demonstrate the flow of events within the sample application template, four event scenarios will be examined: Macro closed successfully, device not open, tablet not open, macro recording in progress or macro not open.
Clears the packet queue removing packets queued but not yet delivered. This means the BIU 32 can be changed to accommodate various host systems without changing the rest of the Circuit.
The 32180 size for these packets is always two words.

Architecture using dedicated endpoints and protocol for creating a multi-application interface and improving bandwidth over universal serial bus. Hard-coded templates necessarily restrict template translation activities to the time of digitizer manufacture or creation of the application program by experienced computer professionals and do not afford the typical computer user the ability to modify or even create their own templates.
Moves an existing region in the tablet coordinate system to the rectangle contained in packet words 3 through 6which comprise two points in tablet coordinates: They encompass all packet types of the Interface and are mutually exclusive in that regions with Stored Procedures may not be included in macros. It is the only module described herein which is dependent on the host system but provides host independent signals to the PIO Since regions are often used to signal user commands to an application program, macros may trigger multiple commands to the application each time they are replayed.

The system reset signal RESETis active-high and must be inverted through hex inverter and converted to an open-collector signal by for use by the circuit.
This is utilized by connecting the microprocessor's 38 reset pin to the PIO, the purpose of which is discussed further on. Region 0or the display region, will be created within the tablet coordinate system bounded by the rectangle, or lower-left and upper-right, respectively.
In addition to transmitting coordinate data to the host computer, digitizers often accept commands from calvomp host computer governing the operating characteristics of the digitizer. This is in contrast to Stored Procedures which execute stored commands without application intervention.
Information transmitted to the host computer is encapsulated in a specific format comprising multiple characters of data which are grouped into the button information and coordinates. Finally, assume the user moves the cursor across the digitizer device surface and positions it over Region 9 before releasing button 1. Macro ended successfully, device not open, tablet not open, region not open or procedure not opened.
The interface may be configured to operate many digitizers from a single host. This signal appears on at the Q output of the flip-flop with preset and clear and is a logic-high when the data buffer is full labelled IBF Method for developing physical disk drive specific commands from logical disk access commands for use in a disk array.
Upon execution of this Stored Procedure, Region 9Region 10 and Region 12 will be disabled and the Interface will be collecting and saving event packets in a macro queue for later playback.
The output from calocmp transparent latch 40 is held stable throughout the bus cycle and provides for additional address decoding in order to distinguish between data transfers to and from external memory and the PIO. Region opened successfully, device not open, tablet not open, region already open, region bounds illegal or insufficient memory to open region. A method implemented by a first computer program running on a computer for transferring information from any one of a plurality of digitizers with different event packet output formats to a second program running on the computer, in a consistent format, comprising:.
Now assume the user moves the cursor over the digitizer surface until it is positioned over one of Region 1 through Region 4 -
