Welcome to the 2.4.22 release of Logic! Much like the last release, 2.4.14, the team has been focusing primarily on still unreleased functionality. That said, quite a bit has changed under the hood. Astute readers may have noticed that we’ve skipped releases 2.4.15 through 2.4.19. These releases went out through a private alpha program. If you would like to learn more, please let us know.

We recently released Logic 2.4.20 and 2.4.21 to a small audience. The changelog below includes all changes from 2.4.20, 2.4.21, and 2.4.22.

Improvements

• Added “Auto Layout” feature, which automatically manages your channel heights to best fit the window. This can be enabled from the right-click menu of any channel. (video below)
• Performance improvements in the digital data processing and storage pipeline.
• Relaxed limits on horizontal zoom and pan, making it easier to zoom in or out on the edges of the data set, and overall help keep these limits from getting in the way.
• Expanded Linux udev install instructions to include extra step required to get udev rules to load.

Bug Fixes

• Fixed bug where the faster you tried to zoom using a mouse scroll, the slower you would zoom. Also improved trackpad and mouse wheel zoom sensitives.
• Fixed issue in parallel analyzer where protocol results would not be visible when decoding dual-edge data at extremely high clock speeds.
• When you load a saved capture that used a digital trigger, it’s now possible to view the required high/low conditions in the trigger settings of the loaded capture.
• Fixed a crash when trimming 100% of the data from a capture.
• Fixed a crash when running the software as the SYSTEM account on windows computers.

Also, this release contains a new protocol analyzer, contributed by Dmitry Grinberg, for the Intel 4004! learn more here. He developed this to debug Linux running on an Intel 4004, which takes 4.76 days to boot.

2.4.14

It’s been a little while since the last release. Most of our development efforts continue to be focused on functionality we’re not ready to announce, and in the meantime, releases tend to be on the lighter side.

Thanks everyone for the feedback on the toolbar. We’ve reduced the toolbar height by a total of 36 pixels, by making the design more compact, and removing some recently added height from the timing display. As always, please leave your feedback!

Improvements

• Updated the toolbar and timing display at the top of the application to save space to display more channels at once.
• Moved the device settings back into the sidebar.
• Removed the lower-right corner menu. The top of window/top of screen menu is now the main menu.
• Improved onboarding dialog for first time users.
• Improved session placeholder, which is displayed when no tabs are open.
• Added support for the latest hardware revision of the Logic 8. This is the last planned hardware revision change. Let’s all pray that we don’t see another supply chain shortage for a good long while.

Bug Fixes

• Fixed issue with automation API where when calling the start capture command, the capture would not actually start until slightly after the command returned. This could lead to missing what you are looking for. Now the device is guaranteed to start recording before the start command returns.
• Updated the Electron version, which among many small things improves rendering reliability on Linux.
• Fixed a bug where on Linux the application would crash when recording 1 digital channel at 1 MS/s.

2.4.13

Welcome to the 2.4.13 release of Logic! This release contains a lot of changes under the hood, especially to how we save and load files.

Older files will load just fine, but files saved with 2.4.13 will not load into older versions of Logic.

If you run into any troubles with the release, please be sure to let us know.

Also, thanks to many of you for the feedback on the UI changes in the last release! We’re reviewing that now and I expect to incorporate some of the feedback in the next release.

What’s New

• Added support for the latest Logic Pro 8 hardware revision. This new revision use a slightly different FPGA part number, due to supply chain issues from last year.

Bug Fixes

• Finally, we’ve fixed the Linux 4GB memory limit. We are now using a custom build of Electron on that platform to solve the issue.
• We fixed 2 issues introduced in the last few releases
  • We fixed the crash when changing the IO voltage level on the original Logic 16.
  • We fixed the crash on Linux when opening the software with a device already attached.
• This is only about 10% of the changes in this release. The other 90% of the changes should not be visible now, but were made in support of future functionality.

Welcome to the 2.4.11 release! This software release contains a significant UI refresh to core parts of the application, and we would love to get your feedback.

First, we’ve added a small toolbar to the top center of the application, centrally locating the capture button, as well as adding buttons for measurements, timing markers, and analyzers. This should make these features both easier to discover and faster to access.

Second, we’ve done a light reorganization of the sidebar. One of the big pain points of our existing sidebar was the difficulty in organizing the size of different sections within one sidebar. To eliminate this problem, we’ve split the timing markers, measurements, and notes into their own sidebar sections. One possible drawback is that it’s no longer possible to view these sections at the same time. We would love to get your feedback on this!

Third, we’ve relocated the device settings from the sidebar into a new flyout menu accessed from the top left of the application. Users who’ve used our older Logic 1.x software will notice a similarity with our older software. The main goal here is to elevate the device settings above the rest of the application features; the device settings button is now the largest item in the application.

Fourth, we’ve invested in the device list menu. The bottom left of the application now houses the connected device list. This does a few things. First, without any interaction, it helps inform users if they have a device connected to the software or not. This makes it easier to tell if a device is connected and working with the application. Although the software is typically used with only one device at a time, for applications where multiple devices are connected at once, the device list menu makes it easier to access those devices. In this specific case, the add session button will also prompt the user for which device they should use, making it easier for the user to manage recording with multiple devices connected.

This release also contains a handful of small UI fixes to dialogs and notifications.

Lastly, we’d like to address the purpose of these changes, and what we’ve been working on at Saleae. As you may have noticed, the pace of public facing software updates has slowed. For more than a year, the team’s focus has been squarely on developing the next generation Saleae product, and most of that work will not be visible until that product is released. We’re not ready to make more details available, but we would like to share that the Logic 2 software will continue to be the central tool for all our products, and we’ll continue to invest in new functionality that benefits existing and future products.

We would love to hear from you! Please let us know what you think of these UI changes, and report any issues that we may have missed.

Improvements

• New toolbar
• Device settings moved to the top-left of the application
• Small sidebar changes
• New device list menu
• Fixed display issues with several dialogs and notifications

This is a pretty small release - most of what we’ve been working on is still under development and not ready for release.

Logic Pro 16 Revision 10

This release includes support for the newest hardware revision of Logic Pro 16, revision 10.0.0. If you’re wondering what’s new, this hardware revision is another small change in a long list of small changes to deal with supply chain issues. That’s mostly behind us now, fortunately. If you’re curious, at the start of the supply chain shortage, Xilinx, the vendor who makes the FPGAs our devices previously used, completely shut down production of the Spartan 6 FPGA line. Very few FPGAs were available from any source at any price, but we managed to pull though by purchasing a wide variety of Lattice ECP5 FPGAs. All the FPGAs we bought are in the same package, but we had to buy a wide variety of speed grades and densities, since no single part number was available in the quantities we needed. Every time we change part number, we need to generate a new bitstream for the part, so a software update is required. Hardware revisions 4 through 10 are just this - slightly different FPGAs.

SmartScreen Notification

In addition, our code signing certificate for Windows expired recently, so this is the first release of the software with the new certificate. Normally this isn’t noteworthy, however Microsoft Defender SmartScreen, the system on Windows computers that protects the users from a wide variety of issues, operates on a “reputation” system. What that means is that software that was been signed with a new certificate that hasn’t been seen before will trigger the “Windows protected your PC” message, similar to the screen shown for unsigned software. This is annoying, and unfortunately will likely cause some confusion with this update.

If you see this screen, please let us know! We expect it to stop showing up pretty quickly.

To install the software, click “More Info”, and then “Run anyway”

You can manually validate the code signing certificate on the installer by right-clicking the installer and opening properties, then navigate to the “Digital Signatures” tab.

There you should see our signature, which you can select and open the details for:

What’s New

1. Support for Rev 10 Logic Pro 16 hardware. No actual change in functionality, this revision uses yet another slightly different FPGA model.

Bug Fixes

1. Not a bug, but our code signing certificate for Windows expired recently, so we have replaced it with a new one. If you see a “Windows protected your PC” message, this is a byproduct of how new our code cert is. Microsoft tracks “reputation” for code signing certificates, and over time this message will go away.

You might have noticed that 2.4.8 was just released. That release broke one of our protocol analyzers for some Linux users. 2.4.9 replaces that release. The changes listed below include all changes in 2.4.8 and 2.4.9.

This has been a long time coming! 2.4.7 Was released over 3 months ago. We’re happy to finally release native Apple Silicon support, as well as a trove of small improvements that have been piling up. We also spent a LOT of the last few months overhauling the build system for Logic 2, which has been holding us back for a while. While invisible to our users, these changes improve developer efficiency, as well as solve a few large issues we have been facing recently.

If you missed it, we recently released a new light theme. Learn more here. Feedback appreciated!

If you missed it, we recently released an automation API for Logic 2. You can learn more at saleae.com/automation. Feedback appreciated!

What’s New

• Native Apple Silicon Support! Note, you will need to download the Apple Silicon version from https://www.saleae.com/downloads/, the auto-updater will not automatically switch users from the x86_64 version to the Apple Silicon version.

Improvements

• Fixed bug where if you shrink the analyzer terminal, and then expand it again, some contents would be deleted.
• Clarified tooltip description of trim pre-trigger data feature.
• The about dialog now shows the app’s CPU architecture (x64 or arm64) and also indicates if it’s interpreted by Rosetta 2.
• When you select a timing marker or measurement, with the measurements sidebar open, and that item is out of view, it will now be scrolled into view automatically.
• When switching between tabs, your scroll position in the protocol data table is now preserved.
• The analyzer settings dialog will now make sure that numeric entries like baud rate are within the allowed range.
• The analyzer settings dialog now lets you completely delete a numeric entry, instead of always entering the value 0.
• Added visible border between protocol results on the graph when they get very close. Before, they would blend together.
• Turned off feature where the add analyzer menu would scroll when the mouse is moved near either end.
• Increased the minimum distance between analyzer overlay markers (like start/stop bit indicators) to prevent them from piling up.
• Updated to the last release of Electron 19, which brought in a few window manager fixes.
• Made dialog scroll bars always visible to make them easy to find.
• Removed the “padding” from the zoom to range feature. Now when you select a range to zoom to, you will get that exact range.

Bug Fixes

• Fixed issue where some analyzers didn’t load on older versions of MacOS. We support MacOS 10.14+.
• Fixed the bug where keyboard shortcuts like left and right arrow were still active when the MacOS save or load dialog was open.
• Fixed UI bug with the measurements comment box.
• Fixed bug where unitless measurements would display the unit “undefined”.
• Fixed issue where the scroll wheel would cause some numeric entries in the application to change value.
• Fixed bug where the main horizontal scroll bar hover style would get “stuck” after use.
• Fixed bug in 2.4.8 that broke the Atmel SWI analyzer for some Linux users.

We’re still collecting feedback on the new light and dark themes we released in 2.4.2!

• We would love to get your feedback!
• Please report any issues you find, and include screenshots. This thread is a good place to post them.
• We will hold back this release from auto-update until we are able to get more feedback, and fix any issues we may have missed.
• For printing, we recommend disabling “color-match waveforms” in the preferences, so that all traces are black.
• We didn’t add a built-in screenshot in Logic 2, because we think the built-in OS features are pretty great these days. That said, let us know if you would still like this feature.
  • on Windows 10/11, press windows key + shift + S to easily screenshot a region of the screen or an entire window.
  • On MacOS, use command + shift + 5, which offers even more features.

Improvements

• Support for several new HW revisions. Logic 8s and Logic Pro 16s shipped starting in December 2022 may require this SW release or newer. No changes that effect end users, we’re just continuing to ride the supply chain roller coaster.

Bug Fixes

• Fixed issue with analyzer progress reporting for captures that have had their data trimmed.
• We rolled our Linux build system back to Ubuntu 18. the releases, 2.4.1 and 2.4.2, were built with Ubuntu 20, which increased our minimum required glibc version, breaking the app for RedHat / Rocky Linux users, and similar distros.

In case you missed it, here is a quick sample of the new theme introduced in the last release.

Measurement API

Note: We have fixed the issue blocking users from previewing this API

We’ve expanded the capabilities of the Measurement API with a focus on Analog channels as part of a longer term product development plan to help our customers verify, debug and test analog problems such as signal integrity issues and much more. Please keep in mind that this API is a preview-release, and we're planning on making breaking changes before it's finalized. Because of this, measurements utilizing the new API can't be published to the marketplace. We’d love to hear your feedback on these changes.

• Measurements now include the ability to display an annotation to help visually aid in the understanding of a measurement. We currently support showing or hiding annotations for all measurements enabled for a range.
• Each range can have its own set of measurements
• We’ve updated the styling of measurements in the sidebar
• The measurement API has new capabilities. More details can be found here

Note: In order to test the new capabilities of the Measurement API you will need to set an environment variable in your shell or command prompt and start the app from the terminal.

Windows: If using Command Prompt:

set ENABLE_MEASUREMENTS_V2=1
C:Program FilesLogicLogic.exe

If using Powershell:

$env:ENABLE_MEASUREMENTS_V2=“1”
C:Program FilesLogicLogic.exe

Mac:

export ENABLE_MEASUREMENTS_V2=1
/Applications/Logic2.app/Contents/MacOS/Logic

Linux:

export ENABLE_MEASUREMENTS_V2=1
./Logic-2.3.48-master.AppImage

Improvements

• When switching tabs the name will appear in the window title
• Added ability to select text in release notes to allow for copy and paste

Because of this, measurements utilizing the new API can't be published to the marketplace. We’d love to hear your feedback on these changes.

• Measurements now include the ability to display annotations to help visually aid in the understanding of a measurement. We currently support showing or hiding annotations for all measurements enabled for a range.
• Each range can have its own set of measurements
• We’ve updated the styling of measurements in the sidebar
• The measurement API has new capabilities. More details can be found here Note: In order to test the new capabilities of the Measurement API you will need to set an environment variable in your shell or command prompt and start the app from the terminal.

Windows: If using Command Prompt:

set ENABLE_MEASUREMENTS_V2=1
C:Program FilesLogicLogic.exe

If using Powershell:

$env:ENABLE_MEASUREMENTS_V2=“1”
C:Program FilesLogicLogic.exe

Mac:

export ENABLE_MEASUREMENTS_V2=1
/Applications/Logic2.app/Contents/MacOS/Logic

Linux:

export ENABLE_MEASUREMENTS_V2=1
./Logic-2.3.48-master.AppImage

Jump to Time

• You can now jump to a specific time in your capture using Ctrl+J

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.

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.
• New analyzer sidebar icon.
• New icons for jump to next edge, jump to next protocol result, or jump from data table to timeline.
• Analyzer trigger now shows user edited analyzer names, making it easier to tell analyzers apart in the list.
• 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.

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!

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
