The desktop GUI now exposes two operator-facing test modes:

• All: all checked channels receive the current configuration and run together for the requested pulse count.
• Sequential: the GUI runs checked channels one at a time for counted-pulse tests, advancing automatically after each channel finishes.

Default desktop behavior:

• Sequential is the default test mode.
• Auto-polling is enabled by default at 1.0 s.
• Auto-poll controls are available on the execution step.
• Injector data can be loaded and saved from the GUI using a simple text profile that stores injector flow and deadtime curve points.

Wizard Flow

The desktop GUI now uses a 3-step wizard:

1. Connection: choose a serial port, connect, and verify communication with the controller.
2. Test Type: select Simple or Advanced, then configure only the controls for the selected mode.
3. Execute: start or cancel the test and monitor progress and channel state.

Connection requirements:

• Step 1 must be completed before advancing.
• Next remains disabled until the controller is connected and connection verification succeeds.
• Verification is required before the test setup pages can be used.
• Connection verification checks both a VERSION response and a STATUS response from the controller.

Test configuration:

• Simple reuses the basic counted-test inputs for model, RPM, duty, and pulse count.
• Advanced reuses the calculated test setup with derived duty cycle and pulse count.
• Test Mode still controls whether checked channels run together (All) or one at a time (Sequential).
• Only the selected mode's configuration UI is rendered on step 2.

Execution page:

• Start Test applies the selected mode's settings to the checked channels and starts the run.
• Cancel calls the global stop action and stops all channels immediately.
• The status area below the buttons shows the progress label, progress bar, firmware summary, and per-channel status table.
• Auto-poll controls are also available on this page while monitoring an active run.

Navigation rules:

• Back-navigation is blocked while test_progress.active is true.
• The mode selector and wizard navigation controls are disabled during an active test.
• Back-navigation is re-enabled automatically when the test is no longer active.

Run

Install dependencies:

python -m pip install -e .

Start the desktop app:

python -m desktop_app

Or, after installation:

injector-tester

By default the UI points at /dev/ttyACM0; change the port in the connection bar as needed.
