show logpanel
- Error when recording data exceed buffer size by one sample resulting in error in console.
- Window stats where off by a factor of 1000
- Navigable minimap, which will display a zoomed-out map of the entire sample. In order to navigate the sample, simply click on the location where you want your window, or drag the slider in along the horizontal axis.
- Zoom to selection button, which will make the window the size of the selected area. Hotkey is ALT+Z.
- Option to toggle logarithmic scale on the Y Axis, by @danielkucera.
- The Y axis settings are now moved into a dialog. To open the settings dialog, press SETTINGS, in the top left corner of the graph. The dialog contains the options to toggle linear or logarithmic scale, and the option to lock the Y axis.
- The chart will now only show positive values along the X axis.
- Backend for interacting with devices from nrf-device-lib-js to nrfutil device.
- Support for Power Profiler Kit (PPK1). From this release, Power Profiler app will only be usable for Power Profiler Kit II (PPK2). In order to use a PPK1, use a version before v4.0.0 or replace the deprecated PPK1 with a PPK2. Removing support for PPK1 allows us to add new PPK2 features to the application.
- Real-Time pane, as this was mainly intended for the deprecated PPK1. The useful Trigger feature will be re-introduced in the Data Logger pane in an upcoming release.
- PPK2 would create noise in the measurement when the LED was pulsing (i.e. PWM), a new firmware (power_profiler_2 1_1_0) has been added and will make the LED static during sampling. The next time you connect to a PPK2 with an old firmware, you will be able to program it with the new version.
- When changing the sampling parameters in the side panel, after having done a sample, it would remove the sample data.
- Zooming further than what is permitted would cause the graph to pane. This is now restricted, which means that if zooming has reached its limit, you will need to explicitly pane the graph.
- Hovering the digital channels would show a horizontal line at the top of the graph. Now the horizontal line will only be shown together with the vertical line if you hover the graph.
- Linux: Missing nrf-udev installation resulted in the app crashing.
- PPK1: Does not work in nRF Connect for Desktop v4.0.1, but will be fixed in the next patch release v4.0.2. In order to work with the PPK1, try downgrading nRF Connect for Desktop to v4.0.0.
- Auto reconnect functionality.
- Update to work with nRF Connect for Desktop v4.0.0.
- Issue in
Real Timepane, where if you increased theLength, the length would not be reflected in the window of the next trigger.
- New PPK2 firmware. The first time you connect a PPK2 with an older firmware version, you will be asked if you want your device to be programmed.
- PPK2 did not show up in Device Selector when the appropriate firmware was not flashed. This release removes the filtering that was introduced in v3.5.0.
- Resuming profiling used to crash.
- PPK1 measurements may fail after some time with error message: "Corrupt data detected, please check connection to PPK". A temporary solution, that we have tested, is to manually downgrade JLink firmware on the device to v7.58b.
- Device filter
- When using a PPK2 you should only select the PPK2 in this app.
- When using a PPK1 you can use it with any member of the nRF51, nRF52 or nRF53 Family.
- Better performance when paning large datasets
- Toggle buttons in off-state are now visible toggles.
- Did not display all serialport devices.
- API support for nRF Connect for Desktop v3.12.0
- App no longer freezes for a long time after it has been sampling in the background for a longer period of time.
- Loading csv files is now restricted depending on the application's architecture.
- Loading larger files are now supported.
- Option to select entire set of samples by pressing
ALT + aor clicking theSELECT ALLbutton in bottom right corner.
- Selection is not removed when returning to Live View.
- Export all now works for all new samples.
- If you are not able to use export
Allwith an older set of samples (loaded from a .ppk file), you may useSELECT ALLand export selection instead.
- If you are not able to use export
- Manually setting y-axis range is now available when
LOCK Y-AXISis toggled. - Export dialog now have a section to choose what selection to export to CSV.
- The different options are to export 'All' samples, the samples within the 'Window', or a 'Selection'.
- The option for 'Selection' is only present if an area of the profile is selected.
- Added icons to Start/Stop buttons in
Real Timepane. - Save / Export is now available after deselecting device
- Be aware that if you select device again the unsaved samples will be wiped
- Advanced option to adjust buffer size is now available, which enables longer
sampling time.
- To display advanced options in the sidebar press
ctrl+alt+shift+a.
- To display advanced options in the sidebar press
- Advanced option to limit supply voltage under Source Meter now available.
- Updated app icon.
- Added icons to Start/Stop buttons in
Data Loggerpane.
- Issue where certain
.ppkfiles could not be loaded.
- Establish compatibility with nRF Connect for Desktop 3.8.
- Two corrupted samples in a row caused all future samples to be corrupt. This would be especially likely to happen in long running sessions.
- Chart issues when loading from saved capture file.
- CSV export had an inverted bit sequence.
- Split the primary view in two, a data logger and a real-time view. With the data logger view the user can examine the power continuously over a period of time. In the real-time view, which has similar functionality to an oscilloscope, the user can specify a trigger level, and when the consumed power reaches this threshold, the power consumption signature in the surrounding period of time can be inspected in detail.
- Trigger: Previously only available when using the older, first version of the Power Profiler Kit hardware now triggers can also be set when using the new Power Profiler Kit II (PPK2) hardware.
- Only with the PPK2: Set a pre or post trigger by moving the slider above the graph, to decide how much time before and after the trigger is relevant and will be shown for the next trigger.
- Average sampling with a lower resolution: When interested in examining power over a longer time span you can lower the samples per second. Sampling is still done at the full resolution, but automatically averaged to decrease the storage size. The rate can be lowered as far as only a sample per second, enabling sampling for days or even months.
- Besides the existing CSV export: Save the current data in a format to Load it again later within the app, enabling sharing data and examining it at a later time.
- Easily create screenshots of the current graph.
- Raise limit for displaying digital channels (on the highest resolution they were previously only shown for a time range of up to 3 seconds, now they are shown for up to 30 seconds).
- Enhanced performance to make the UI more responsive.
- Several minor UI changes to improve the user experience.
- Small visual glitch when used with nRF Connect for Desktop 3.6.1: The top margin in the side panel was shrunken.
- CSV export contained the wrong portion of data.
- Connecting a PPK via J-Link Lite failed.
- Moving the right handle past the left handle in the chart selection would break the values displayed in the selection window.
- Complete rewrite of the application. This version supports the old power profiler kit, in addition to the newly released PPK2 hardware.
