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