We hope that you have had a great start to the year!  February has flown by, even with the extra day tomorrow for leap year.  In this nearly March newsletter, we have:

  • Joulescope UI 1.0.58

  • Embedded World 2024

  • Joulescopes in the Wild

Joulescope UI 1.0.58

We are proud to announce the next Joulescope UI release, 1.0.58. While this release lacks a leading feature, it makes several improvements, fixes issues, and enhances UI reliability.


In the previous stable release, 1.0.48, the UI detected Intel graphics on Windows, prompting you to switch to the software OpenGL renderer to work around issue #216. We have since found that upgrading Intel graphics drivers fixes the problem for most people.  If your Intel graphics drivers are up-to-date and you want to switch back to the accelerated OpenGL driver in 1.0.58, select:
  SettingsCommonopengldesktop

We now recommend using the Intel graphics driver on Windows unless you run into stability issues.


Here are some notable improvements in 1.0.58:

  • Added JLS file recovery when not properly closed.

  • Improved device firmware update process.  You can now opt out.

  • Added safe mode.  Hold shift at start until a window appears.

  • Added dialog sequencing at startup.

  • Performed full audit and fixed numerous issues causing infrequent crashes.

  • And more!  See the full changelog.


The Joulescope UI will prompt you to upgrade when you next launch the UI.  You can also download it here.

Current Consumption Measurement of Modules (Espressif)


A Joulescope customer is using a JS220 for cyclic voltammetry.  In related news, we now have heard about cyclic voltammetry, which is pretty interesting!
