LedDisplayDeviceTest

Qt GUI tool for debugging the Device/LedDisplayDevice protocol without starting ParkingSpaceGuideApp.

The test links the LedDisplayDevice and VrUtils libraries configured in LedDisplayDeviceTest.pro; it does not compile or link the device source directly. Build those libraries with the same Debug/Release configuration before building this project by itself.

Usage

  1. Enter the controller IP, TCP port, screen address, controller type, and dynamic-area parameters.
  2. Click Connect.
  3. Use a state button, custom text, clear, or automatic demo to send data.
  4. Use Screen ON or Screen OFF to issue the controller's forced power command.
  5. Inspect the protocol response log and the physical LED screen.

Controller accepted in the log means the controller returned a valid ACK. It confirms receipt of the command, but only an on-site observation can confirm the visible LED result.

Custom text is encoded as GBK, matching the controller font protocol. The simulator treats the whole configured screen size as one dynamic area (the selected dynamic-area ID, normally 0). The preview is a visual stand-in for that complete physical screen and updates whenever a command is sent.

The power buttons send maintenance command A2/05 with status 0x01 (on) or 0x00 (off), and wait for the normal controller ACK/NACK response.

The device library also supports controllers that use several areas: configure LedDisplayConfig::dynamicAreas directly when multiple records are required. Each LedDisplayArea carries its own position, size, animation settings and optional text. LedDisplayResult::areaTexts can supply text per area at send time; the test GUI intentionally keeps this advanced mode out of the preview.

Package

Build the Release target, then run from the repository root:

set QT_PATH=D:\Qt\5.15.2
GrabBagPrj\pkg_leddisplaydevicetest.bat

For a non-standard build directory, pass the executable path as the first argument. The package script runs windeployqt and writes the deployable GUI to GrabBagPrj\buildwin\LedDisplayDeviceTest.
