Logic 2.3.9 is a bug fix release, that covers several important CPU utilization bugs. Thanks to everyone who reported the problem, sent in captures, and worked with us to help find the root cause.

A quick note on the fix for the decoding problem with I2C and Parallel analyzers when decoding data as it is recorded. We were not able to directly reproduce the issue with I2C. If you see a problem where I2C results are missing, and extra start/stop bits are added instead of decoded bytes, please let us know! We're pretty sure it's fixed, but we haven't been able to verify it directly. The bug requires two things - one, it only occurs when running the I2C analyzer on a live capture. It does not occur if you run the I2C analyzer on data after recording is finished. Second, it is sensitive to the specific timing of the I2C data (possibly related to long delays between bytes, but we're not 100% sure). Also, if you've seen this issue in older releases, but not in 2.3.9, please let us know! As far as we can tell, this bug has been in the Logic 2 software at least all year, possibly since we added analyzers to Logic 2.

A note on CPU usage - you should see high CPU usage while analyzers are processing, and while data table indexing is performed. For an analyzer with 100,000 frames produces, indexing should take less than a minute after the analyzer finishes processing. We will be adding an indexing progress indication soon. Once indexing is complete, the CPU usage should drop.

Bug fixes

• Fixed CPU utilization problem with I2C analyzer.
• Fixed decoding problem with I2C and Parallel analyzers when decoding data as it is recorded.
• Fixed CPU utilization problem that occurred when removing an analyzer.
• Fixed CPU utilization problem regarding analyzer data table results population.

Windows - Linux - MacOS

Breaking Changes

• We've removed the combined "ASCII & Hex" Display mode from the application. Analyzers that use this mode will be converted to Hexadecimal. We've made this removal to support a large protocol analyzer data table update. The removal of this display mode significantly improves on our ability to index and search protocol data.

What's New

• Analyzer data table has had a massive Overhaul!
• Data table rows are always in time order now.
• Search matching is much more intuitive, with substring search fully supported and the ability to exclude columns from search.
• Data table cells now have a tooltip to show their complete value.

Improvements

• Data table cell formatting improvements, especially for HLAs that produce byte arrays.
• Added highlighting to the analyzer data table to show cells that matched the query.
• Moved the "show analyzer in data table" option from the analyzer menu to the data table menu.
• Analyzer trigger view now shows the user-editable name of the analyzer selected for the trigger.

• Added link to the users guide.

Bug fixes

• Floats returned by HLAs that happen to be integers will now be treated as floats correctly.
• Implemented support to properly maintain accuracy with 64 bit integers produced from HLAs.
• The scroll bars on the analyzer data table are now consistently visible.

Windows - Linux - MacOS

Breaking Changes

• ASCII display formatting for all analyzers has changed. Now, non-displayable ASCII characters will be displayed as their hex escape sequence, instead of falling back to base 10 display. For example, the character 0x1C, which is not displayable, previously would be shown as '28', but now will be shown as x1C. This affects all protocol decoders and their export files when the ASCII display radix is selected. We also fixed the COMMA problem, it will now be shown as , in the application, however in exports it will still be replaced with COMMA until we eventually replace the protocol export system with one that is CSV safe.

Improvement

• data table infrastructure - Elasticsearch was a constant pain, mainly for Windows users. We replaced it with a faster and more stable DB (RocksDB). Cmd/ctrl+click on a graph result was removed temporarily. The data table currently supports only Async Serial, I2C and SPI. We'll add the rest of the analyzers soon.
• Terminal - Faster and lighter (CPU wise) streaming of analyzer results. Async serial, SPI and I2C output looks great now :)
• Digital trigger performance improved significantly and we can now keep up with most 10MHz signals
• Analyzers are now 5-10X faster - we can keep up with most 10MHz signals
• Digital edges snapping threshold was reduced to support dense data
• App size was reduced by half (!)

Bug fixes

• High-level analyzers - restore position and name correctly, when launching the app, loading a file or restarting a capture
• Hard crash in analyzers was fixed
• Analyzers - keep settings correctly between runs
• Data management - Redux was replaced with MobX to improve app stability and performance
• Fixed crash when analyzer result tooltip includes a very long text
• Disable zoom in/out keyboard shortcuts in text areas

2.2.8 is a small follow up release after the big 2.2.7 release from last week. It mainly focuses on exception handling and memory management. The app now properly clears old memory when recording in looping mode, and it deletes sessions on a background thread to keep the UI responsive when restarting captures or closing tabs.

Reminder: releases now include a new interface for writing high-level protocol decoders in Python. Check out the documentation here: github.com/saleae/logic2-examples

Bug Fixes

• fixed frequent crash in digital rendering that occurred after some digital data had been deleted
• now properly delete memory when the capture buffer gets full.
• moved session deletion to a new thread, so it doesn’t block the UI.
• changed most USB error handling from hard crashing to an error notification.
• reduced memory usage of digital recordings.

TLDR;

2.2.7 brings dramatic performance improvements to digital capture processing and digital rendering! Our aim was to get the software to run smoothly when recording digital signals near the limit of the devices’ performance. Digital data processing is now 10x faster, meaning fewer “backlogged” captures!

Reminder: releases now include a new interface for writing high-level protocol decoders in Python. Check out the documentation here: github.com/saleae/logic2-examples

Bug Fixes:

• Timing markers now snap to digital transitions again
• saved calibration files are now loaded properly when offline
• analyzer export now respects the currently selected display radix, instead of always exportin ASCII.
• Custom protocol analyzers: if no results are added GenerateFrameTabularText, the frame is now hidden from the protocol results list view
• Traces color now update immediately on change

Behind the scenes:

• detailed performance instrumentation
• significantly improved UI performance in live mode (5-10x)
• dramatically improved processing performance of digital data (10x)
• dramatically improved rendering performance of digital data (3x)
• migrated analyzer management to a better state management system
• refactored processing state updates from the data processing system

Features:

• Custom protocol analyzers that have a “FilePath” or “FolderPath” TextSetting now have UI to select files or folders
• press Ctrl+0 to reset text zoom (ctrl +/- zooms text size)
• Cmd/ctrl+click on a decoded protocol result opens the analyzer sidebar tab and scrolls to that result
