Revision History - v10.0.0

Daqarta v10.0.0 - 22 January 2017

Engine_Sim Engine Crank and Cam Sensor Simulator macro mini-app updated to allow optional Custom Profile List text files of tooth positions and widths to replace parameter-based profiles for Crank or Cam sensors, or both.

Square wave option in Generator now includes dialog to select Snap or Interpolate edge transitions. Help topic also includes discussion of how to use Burst to create 'perfect' square (or sine) waves at very low frequencies below 1 Hz.

New Arb_From_Equation macro mini-app added, with 31 Arb waveform files now included in Daqarta distribution, plus full code and waveform images in Help.

New MemArb Save command allows saving the full contents of a MemArb waveform to a disk file for subsequent use as a normal Arb file.

The included MemArb_To_File macro was rewritten to use the above MemArb Save command, greatly simplifying it.

The included Arb_From_List macro mini-app now uses the new MemArb Save command, creating a MemArb in the ArbTest.GEN Generator setup to provide a real waveform that can be measured with the cursor readouts. It also now allows negative values (not needed for the RPM_Ramp_List.TXT example shown), as well as allowing Arb files of 1024, 2048, 4096, 8192, or 16384 samples by changing a single parameter. (The prior version was limited to 1024.)

Macro Array file operations now allow headerless (.DAT) files to be saved as signed 32-bit integers instead of the default 16-bit, by preceding the save with Buf0#W=32.

Macros that use Arb and Play file commands Arb0 to Arb7 or Play0 to Play7 can now use ArbV or PlayV to refer to the previously-set Ch Channel Select variable instead of an explicit 0-7 button number.

Bug Fix: Update installation from prior Daqarta version did not automatically enable channel display buttons on some systems.

Bug Fix: Single-screen (1024-sample) non-DQA files (WAV, DAT, or TXT) that were opened for viewing could not be closed by toggling the DD/Open button back off. (Bug introduced in v9.00.)

Bug Fix: The Frequency Counter didn't work properly with Trigger mode set to Gen Sync when using Burst, Train, or Sweep sync options.

Bug Fix: If Decimate was used when reading a DDisk file, the display was not always updated properly when the Decimate Factor was large enough to show the entire file on one screen.

Bug Fix: MemArb command to write a variable to a specific index such as MemArb0[UA]=X, as well as copying from a macro array buffer such as MemArb0="<=B1", failed to round properly in converting real values to MemArb integers.

Bug Fix: Macro Array Buf0-Buf7 commands like Buf0#W=n, Buf0#WO=n, Buf0#WU=n, and Buf0#w=n to specify the data width and format for reading from a (headerless) .DAT file were not properly applied to the specified buffer, except Buf0.

Bug Fix: The WAV_to_16bit file converter macro was inadvertently omitted from the default macro collection.

Bug Fix: Using the A. macro prefix to load an Arb file directly, without an Open dialog, caused the command to fail if the file type was .TXT, as in A.Arb0="MyArbFile.TXT". No problem with .DQA, .WAV, or .DAT files.

Bug Fix: Trigger Auto Mode or Auto-Level mode failed to update display of the Generator output in the case where no trigger event was found after a change to any control in any Generator dialog.

Bug Fix: Under certain conditions the calibration file was not read properly, causing the input line to be reported as uncalibrated.

Bug Fix: On Windows Vista and later systems, the Y axis could be shown as calibrated for Generator outputs even though it was not.

Bug Fix: On sound cards that report 192 input level steps when they actually only have one level, the Input Level control behaved strangely.
