• FIXED: X axis labels incorrectly displayed in spectrum analyzer mode when there is no data
• FIXED: no settings update when sensitivity/sampling/trigger trackbar position was changed using keyboard
• added slow signal recorder mode
• enabled main form hints, added hints for toolbar buttons
• added progress bar representing received part of expected data buffer from device
• armscope.dll: libusb updated to 0.1.12.1
• turned off "Use dynamic RTL" option (no dependency to cc3270MT.dll)
• cursors are drawn on top of actual plot line
• current X and Y axis zoom displayed on toolbar
• added build timestamp to "About" and build-tools\touch.exe to build chain
• added Statistics.cpp/StatisticsUnit.cpp - calculation of min, max and avg value
• added dialog on startup when no input device dll is selected
• added option to export plot image to bitmap file (File menu)

Version 0.00.08

• FIXED: AV at startup if input library was not found
• data vector passed do display represents physical value, not ADC output
• offset and sensitivity calibration for each sensitivity range (if supported by input dll)

Version 0.00.09

• FIXED: leading backspace in default filename when saving plot as bitmap and default directory is empty
• ScreenSnap changed for some of the windows
• added fancy hexagonal toolbar for plot (toggled by middle button)
• selecting input device dll is now required, application will abort if device is not selected
• added feedback form for loading device, initial loading moved to TfrmMain::OnShow
• added simple plot data export to JSON and CSV format

Version 0.00.10

• FIXED: random halt (typically with continuous trigger when system CPU load was high); VCL code (reading GUI state) removed from CallbackTriggerFn
• FFT is calculated only after receiving full expected data frame from device

Version 0.00.11

• FIXED: zoom was not cleared in recorder mode; simplified ActionZoomClearExecute
• display: auto adjusting plot zoom and position for Y axis
• display: added enum E_OFFSET_ACTION to Display class to allow leave offset untouched or clear it calling SetZoom
• display: X offset is not changing when using Y axis zoom, Y offset is not changing when using X axis zoom

Version 0.00.12

• FIXED: plot grid visibility options had no meaning in recorder mode
• statistics updated after receiving full frame (same as FFT) and when statistics window is opened if full frame is already received
• statistics window is not shown until device dll is loaded
• added signal frequency measuring to statistics
• added transparency setting to plot toolbox; setting is ignored if tranparency is not supported by OS (i.e. Win98)

Version 0.00.13

• FIXED: project failed to build if there was space in project path (incorrect Pre-Build tools command), thanks to £ukasz for report
• FIXED: FFT was not displayed or displayed incorrectly if data buffer size was not power of two
• SOLVED: high CPU usage by plot was side effect of using CodeGuard; with CodeGuard turned off (release build) drawing 14k samples takes less than 3 ms on Pentium M @ 600 MHz + ATI R9000 set (30 times faster than previously), d'oh!
• added auto adjusting plot zoom and position for X axis
• nicer log window
• added TimeCounter.h - utility to measure execution time
• added info about CodeGuard usage and debug build in About window

Version 0.00.14

• FIXED: on some low-end computers there was blank rectangle (size of the save dialog) visible on image exported to clipboard or file
• FIXED: incorrectly displayed sensitivity, sampling and incorrect visibility state of buttons related to trigger types when failed to connect to device on startup
• added JSON file viewer
• oscilloscope control panel is disabled if device is not connected
• receive progress bar is hidded when not waiting for data
• reduced size of exported bitmap file (changed format to 8 bit)
• added standard File/Exit action

Version 0.00.15

• added signal processing framework with few simple filters based on factory pattern
• added CompileTimeChecker.h (STATIC_CHECK(expr, msg) macro)
• changes to data collecting and drawing: data is buffered in dataOscTmp vector and written to main/displayed buffer (dataOsc) only when temporary buffer acquired full frame or main buffer is not filled yet
• creating TBitmap for data export is now part of ConcreteDisplay
• FIXED not working saving plot to bitmap and clipboard on windows vista (thanks Jakub Nizio³ek for the report)

Version 0.00.16

• FIXED no display update/redraw after loading JSON file (thanks Jakub Nizio³ek for the report)
• added data recording to custom binary format (MS3)

Version 0.00.17

• FIXED FFT view not updated when switching viewed frame from MS3 file
• FIXED: can't switch to FFT mode when there is no device connected but data frame is loaded from MS3 file
• FIXED: incorrect (always "Skipped (non-compatible) libraryname.dll") log message when failed to load/verify input dll (i.e. when loading library failed because some additional dependency was not met)
• FIXED: possible access overrun when opening damaged/false ms3 file
• device interface: cookie is not checked inside OnLog callback
• configurable size limit for MS3 files (100 MB default, range from 5 MB to 4000 MB), recording is stopped when limit is reached
• added new notification window to show messages in a non-blocking way (i.e. when recording was stopped because of file size limit)
• limits for sampling interval of average value recorder (third mode next to FFT, do not confuse this with lately added MS3 recorder): 10 ms ... 7200 s; added OK button to set interval value (previously: value was changed with any change in edit control, value may temporary switch to default when edit control did not contained valid float string)
• MS3 viewer allows to select and view multiple subsequent frames at once; selected frames must have same sampling frequency (currently only this parameter is checked)
• MS3: added "file already exists" warning when selecting file for recording

Version 0.00.18

• FIXED: problem with limits of average value recorder sampling interval
• added tool repairing damaged ms3 files with missing file footer/index; this is the only only realistic type of damage - it may happen when program was killed (or - hopefully not - halted) in the middle of recording

Version 0.00.19

• FIXED: possible EZeroDivide exception at glViewport() function in DisplayOpenGL module due to unitialized iWidth, iHeight variables at startup
• added dll version info to Settings / input plugin list

Version 0.00.20

• FIXED: possible AV error at startup caused by static variables initialization hazard (DataFilterFactory::Register() called before DataFilterFactory type object was created)

Version 0.00.21

• added FFT window selection built upon factory pattern; each window type comes with short descriptions and windows are sorted by main lobe width (currently: rectangular, Hamming, Hamming, Blackman-Harris and flat top)
• added limit of samples used to perform FFT setting; number of samples used for FFT calculation equals power of two lower than size of captured data frame
• changed default plot zoom and offset in FFT mode (there is no point in showing negative scale)
• statistics: added RMS value measurement
