Change Log

Commit CogView graphics upgrade completed

  • Release Version v22.09.02.
  • Refactored Spin memory view completed:
    • Improved redraw of memory data, with faster drawing of headers, address column, and main memory values itself.
    • Added a new program setting for drawing top and bottom headers.
    • Added GUI/DrawingSectionManager.cs and Utils/EnumTraverseExtension.cs to help to ordered drawing of every section.
  • Improved graphics render quality of text and graphics elements on custom controls: CogView, MemoryView, SpinView, HubView and CogView. Marginal impact on performance, by improvements in drawing algorithms on each control.
  • Added Icon suport for floating windows.
  • Cleaned code for double-buffering on CogView, MemoryView, SpinView.
  • Removed unused referenced assembly: PresentationFramework. Prevent not found dependencies error when open GEAR project on MonoDevelop.
  • Added documentation on some empty description methods.

Commit 4e679f0 CogView graphics upgrade

  • CogView graphics upgrade: use system highlight color for current executting line (program cursor).

Commit bbee325 Doxygen documentation upgrade part 1

  • Doxygen documentation upgrade: changed to xml style for many tags (summary, remarks, returns).

Release Version 22.09.01 Commit 87d906d CogView appareance enhanced.

  • Changes on CogView.cs:
    • The appareance of the current executting line (program cursor) now is selectable program setting. Can be bold text, a frame around the text line, or both.
  • Gear Emulator window starts now with a size of 1024x768, to help to standarize documentation images.
  • Updated .gitignore : added more visual studio and vscode definitions.
  • Updated secuence diagrams files: Changed extension .mcsgen to more standard .msc. Changed path of documentation files to Doc/sorce/. Modified doxygen documentation accordlingly.

Commit 1e6cd95 CogView, SpinView and MemoryView optimizations.

  • Refactored code to improve performance, using double buffering on CogView, SpinView and MemoryView.
    • Refactored drawing logic to be time efficient.
  • Changes on CogView.cs:
    • In SPIN interpreted mode, now up to five memory values are showed, conforming an encoded instruction. The show memory button now shows the binary representation of each instruction, using the same length of bytes of the instruction.
    • When cog is running in PASM native mode, the hovering message now explains more, giving details if origin or destination fields are used by the instruction, if them are using a inmmediate value, or a pointer to a memory and its value.
    • When following program cursor, the panel is completely white, else grey. This simplification allowed to accelerate of drawing, by removing variables and operations.
    • The spin interpreted details are drawn like a separated panel. The stack now have a header, showing its length, and have a level number.
    • The default start value of display decoded program values as hexadecimal or decimal, now is a program setting.
  • Using Parallel proccesing to improve performance:
    • Initially fill the array of color brushes used to paint each byte of SPIN map (32KB), using Parallel.ForEach with automatic partitioner. Also, generate icons for each type of node of tree view in a separate thread. Both changed in SpinView.cs.
  • Added methods to determine the length of SPIN instruction, advancing the memory accordlingly on InstructionDisassembler.cs and MemorySegment.cs. Also added methods to get binary text representation of PASM instruction.
  • Corrected reset values on TV & VGA Plugins.

Commit 1a8a849 Minor changes previous to CogView optimizations.

Commit eea6143 Reset image on TV & VGA Plugins 2nd part.

  • Corrected plugin files added.

Commit 0e2e5b2 Reset image on TV & VGA Plugins.

  • Added OnReset() methods on Television and vgamonitor plugins: now the screen is cleaned when the user reset the emulator.
  • Corrected resources files to be validated against XSD schema: using the correct http: prefix, to be correctly validated on VS Studio 2019. Apllied to all *.resx files.
  • Fixed format of resharper commentaries.
  • Added Parallax Propeller as vector images: .svg files.

  • Bug Correction on first plugin loading on a fresh instalation of GEAR, related to LastPlugin application setting.
  • Corrected a bug in references list: it was possible to add a blank line to the list.

Version 15.03.26

  • Corrections on all the effects for PASM hub operations (zero, carry and return): CLKSET, COGID, COGINIT, COGSTOP, LOCKNEW, LOCKRET, LOCKSET, LOCKCLR. There was some missing values for carry & zero flags.

  • Algorithm optimization for PropellerCPU.PinChanged() to determinate the pin state faster for DIR and OUT.

  • Corrected reset events invocations, affecting pins & lock state, and logic view. Now all of them are reset effectively.

  • Improvements on LogicView, to show more helpful messages on errors, labels on buttons and text boxes.

  • In Plugin Editor now you can start with a default plugin template (new default) or empty window (old default style). The program recovers it from "Resources/PluginTemplate.cs".

  • Updated PluginBase class structure, so all the old plugins have to be updated:

    • Constructor invocation must call Base constructor.
    • Extra parameter on OnClock() method for current clock number in tick clocks.
    • Method PresentChip() with no param, because Chip reference now is included in plugin base class definition.
    • New method OnClose() is called for every plugin before closing the emulator (to perform cleanup).

  • Added program settings to remember them between sessions (stored in "Gear.exe.config" file in this version):

    • TimeFrame and TickMarkGrid on logic view.
    • LastBinary & LastPlugin on Emulator, GearDesktop & PluginEditor.
    • UpdateEachSteps to enable changes on the screen refresh rate.
    • Added UseNoTemplate program setting to enable load plugin editor empty (old default style).

  • Changed names and tooltips on buttons "open plugin", "load plugin", "open binary" on GearDesktop & Emulator.

  • Memory leaks prevention: Corrections for Disposable members in CogView.cs, LogicView.cs, MemoryView.cs & PluginEditor.cs.

  • Improved general documentation of source code, including specific pages for sequence of callings for PropellerCPU.Step() and loading a plugin in memory after compilation.

Version 14.07.03

  • Faster emulation.

    • In my own testing, GEAR runs now about 30% or 35% faster than Gear V09_10_26, maybe because the executable now use MS .NET framework 4.0 instead of 2.0. The drawback is the need to download the framework, but in windows 7 or 8, probably it is installed already.
    • Also, updated the project files to MS Visual C# 2010 Express (the old proyect was in MS Visual C# 2005). I use that because it was the only I could find.

  • Show Cog RAM Special Purpose Registers values.

    • Now the values of special registers in cog memory (between $1F0 - PAR and $1FF - VSCL) are displayed correctly in memory or PASM view.

  • Logic modes in counters.

    • Logic modes (CTRMODE between %10000 and %11111) didn't work well in past versions of Gear.

  • Correction to enable PAR register changes.

    • As there was some reports of prop forum users that GEAR was of not capable to change the PAR cog register (forum thread "PASM simulator / debugger?") then I enabled it. They claims that some parallax video drivers in PASM changes the PAR register, and GEAR didn't emulate that. The Propeller Manual V1.2 specify that is a read-only register, but if parallax did that drivers that really run on the real one...

  • Fixes in Logic View.

    • When you reload a binary or reset it, and you had run it before using pins, the logic view show a mix between new and old samples.
    • If you are using windows in other languages than english, -with other number formats-, the preset values for time frame and tick mark (with "." decimal separator) will not work if you press the update button.

  • Flickering correction on cog view over PASM lines.

    • When you were on cog view (PASM code), the tool tip text sometimes flickers.

  • Tooltips over pins and locks in hub view.

    • Added tooltips on hub view on pins and locks views (IN*, DIR*, Floating, Lock Free, Locks), to identify easily which pin or lock is.

  • Plugin editor enhancements.

    • Experimental C# sintax highlighting of code. Now the name of the file is displayed on the title of the window. Added tooltips to be more self explaining.

Version 09.10.26 26 October 2009

  • Many thanks to Bob Anderson for identifying bugs in and subsequently testing improvements to the emulation of SUBS, SUBSX, CMPSX and REV.

Version 09.06.05 (140) 5 June 2009

  • Many thanks to Ben Levitt for improving the behaviour of GEAR. (Reload Binary, Open to PlugIn, Close PlugIn)
  • Improvements in SerialIO plugin (Ben Levitt).

Version 09.05.12 (50) 11 May 2009

  • Fixed memory references of the form LONG[ &MyVar ][ 2 ], this case was being emulated as LONG[ 2 ][ &MyVar ].
  • Included SerialIO plugin (with thanks to Ben Levitt) in the distribution.

Version 08.10.16 (151) 16 October 2008

  • An extra function has been added which allows hot keys to be disabled for a plugin. Simply add the following function to your plugin: public override Boolean AllowHotKeys { get { return false; } }.

Version 08.04.29 (159) 29 April 2008

  • The lastest stimulus.zip is now included in V08_04_29.zip.
  • 'R' and 'S' keys can now be used to run, stop and step the currently active cog.
  • Floating the cursor over an assembly cog page shows the values stored at the source and destination registers for the instruction line that's under the mouse. The values are shown as both hex and decimal.

On 23 January 2008

  • Updated stimulus.zip. Still works with V08_01_18 of GEAR.

  • The stimulus plug-in page has a context menu which allows a new stimulus file to be loaded and the current one to be saved.

  • Editing of the stimulus file is allowed - previously it was read-only.

  • As part of the stimulus file, it is now possible to include the words reset and stop.

    • reset - simulates a reset of the processor.

    • stop - causes a breakpoint - click Run to go to the next stop / breakpoint.

      How's this for something you haven't been able to do til now!!

      ! Stimulus File breakpoint example
!  (diagnosing the first microseconds of life)
10u stop
+10u stop
+10u stop
+10u stop
+10u stop
+10u reset

On 21 January 2008

  • Added stimulus.zip which updates stimulus.xml and the example stimulus file. It is now possible to do clock and pwm generation.

Version 08_01_18 (140)

  • Pin toggling by means of a stimulus file.

Version 08.01.13 (86)

  • Better disassembly of PASM.
  • Some fixes in assembly language emulation
  • An alternative / short instruction set for the spin bytecodes (the original is still available).
  • The ability to display numbers as hex or decimal.
  • The ability to add a single breakpoint (just click on a line of code).
  • Improved simulation of the timing from the output pins.
  • Better disassembly of PASM.
  • Some fixes in assembly language emulation.
  • An alternative / short instruction set for the spin bytecodes (the original is still available).
  • The ability to display numbers as hex or decimal.
  • The ability to add a single breakpoint (just click on a line of code).

Version 1.11.0.0

Version 1.10.0.0

  • Fixed HUBOP instruction (source and destination fields were switched).
  • Fixed PAR, now it's the 14 bit value passed, not the data stored at that address.
  • Fixed jitter in the analog view.

Version 1.9.0.0

  • Fixed carry in addition / subtraction operations (most of them at least).
  • Changed the VGA plug-in to be sensitive on sync edges.
  • First official open source release.

Version 1.8.0.0

  • Fixed MIN/MAX/MINS/MAXS instructions.
  • Improved and Consolidated PLL code.
  • General cleanups.
  • Fixed broadcast video emulation.

Version 1.7.0.0

  • Now you can add pin ranges in the text box (12..14 is the equivalent to 12,13,14).
  • Reduced stack usage for interpreted cogs.
  • Fixed COGINIT/COGNEW for interpreted calls.
  • Fixed nested function calls.
  • Added broadcast emulation (possibly incorrect).
  • Changed the way PLLs work, allows for multiple aural hooks (since they are used now).

Version 1.6.0.0

  • Implemented proper interpreted random output (thanks Paul and chip!).
  • Added analog channels to the logic view.
  • Reduced inital pins in logic view to 32 (0 - 31) since those are the only ones anyone should be using anyway.
  • Double clicking a channel in the logic view deletes it now.
  • Added the ability to add digital channels (incase you deleted it).
  • Fixed CMPSUB, frequencys are properly calculated in TV based applications.
  • Increased the number of samples allowed in the logic view from 256 to 1024.
  • Added a good ammount of initial condition checking to the GUI (although there is something wrong if the events occur before the emulator is presented to a plugin).
  • Other little fixes here and there.

Version 1.5.0.0

  • Proper handling of condition field on native instructions.
  • VSCL is now buffered between WAITVID frames (VCFG is not).
  • Changed behavior of Forward and Reverse random (negitive feedback LSFR, rather than rotating buffer with XOR).
  • Timing fixed on instructions.
  • Fixed parity and other various instruction flag issues.
  • A cog stops rather than reboots the chip if the interpreter returns from it's starting function (stack underflow).
  • Increased the size of the virtual VGA monitor plug-in (Bitmap 512x384 VGA runs at 1024x768 with pixel / line doubling).
  • Included a PinNoise plugin, which plays with some pins.
  • PLLs dejitter is now more accurate (uses sub-system clock accuracy).

Version 1.4.0.0

  • Fixed a HUGE problem involving inplace effected memory (interpreted)
  • x /= y was being processed as x := y / x (Which is bad). Order of operations is now appropriate.
  • Changed the name of BusModule to PluginBase class (makes more sense to me)
  • Sped up the interpreted core a little bit (doesn't use the stack for internal temporary variables).
  • Cleaned up the source significantly.
  • Fixed a minor bug in the composite video generator phase shifting code (s-video).
  • Numerous bug fixes scattered about the native and interpreted cores.

Version 1.3.0.0

  • Support for Frequency Generator modes 1-3 (PLL), and VGA video generators.
  • New SPIN memory viewer, but it's incomplete.
