Below are the most notable differences: - -## Formatting -To customize the formatting, open the .clang-format file located in your project. By default, the file contains the following content: - -``` -BasedOnStyle: LLVM -UseTab: Always -IndentWidth: 4 -TabWidth: 4 -PackConstructorInitializers: NextLineOnly -BreakConstructorInitializers: AfterColon -IndentAccessModifiers: false -AccessModifierOffset: -4 -``` -You can also disable formatting for specific folders by using the `DisableFormat: true option.` For example, if you want to disable formatting for the managed_components folder in a project structured like this: -``` -project - - managed_components - - .clang-format - - main - - .clang-format -``` -Add the `DisableFormat: true` option to the `.clang-format` file located in the managed_components folder. This flag tells ClangFormat to completely ignore this specific `.clang-format` file and its formatting rules within the managed-components directory. - -For more information about available style options, refer to [the Clang-Format Style Options guide](https://clang.llvm.org/docs/ClangFormatStyleOptions.html#configurable-format-style-options). - -## Search -The “search text” option in the right-click menu is currently unavailable in the LSP-based C/C++ Editor. However, you can use the toolbar menu **Search > Text > Workspace** as a workaround. - - -## Inlay Hints -The LSP Editor has inlay hints enabled by default. If you prefer not to use them, you can disable this feature by editing the `.clangd` file: -``` -CompileFlags: - CompilationDatabase: build - Remove: - - -m* - - -f* - -InlayHints: - Enabled: No -``` -## Searching ESP-IDF Components -To browse ESP-IDF components, follow these steps: -- Create a new project. -- Add the ESP-IDF components folder as a virtual folder to the newly created project. -- Press **Ctrl + Shift + T** or **Ctrl + Shift + R**. -- You should now be able to browse the ESP-IDF component files. -- To search for a specific function or keyword, use the Search menu in the toolbar. - -Creating a Virtual Folder -- Navigate to **New > Folder.** -- Click on **Advanced.** -- Select **Link to alternate Location (Linked Folder)**. -- Click **Browse** and select the `ESP-IDF components` folder. - -It is recommended to always create a new project instead of modifying your current one to avoid unnecessary Git files and error markers created by the indexer for the components folder. As both the projects will be in the same workspace, you should be able to search anywhere within your workspace. - - -# CMake Editor - -CMake Editor Plug-in is integrated with IDF Plugin for editing CMake files such as CMakeLists.txt. It provides syntax coloring, CMake command content assist, and code templates. - -![](docs_readme/images/cmake_editor_ca.png) - -CMake editor preferences can be controlled using `Eclipse` > `Preferences` > `CMakeEd`. - -![](docs_readme/images/cmake_editor_preferences.png) - - -# ESP-IDF Application Size Analysis - -The Application Size Analysis editor provides a way to analyze the static memory footprint of your application. It has two sections: -- The **Overview** section provides a summary of the application's memory usage; -- The **Details** section will have in-depth details about components and per-symbol level memory information. - -**Details** table viewer also provides you with searching and sorting capabilities on various columns. - -To launch the Application Size Analysis editor: - -1. Right-click on the project. -1. Select `ESP-IDF` > `Application Size Analysis` menu option to launch the editor. - -**Application Size Analysis - Overview** - -![](docs_readme/images/sizeanalysis_overview.png) - -**Application Size Analysis - Details** - -![](docs_readme/images/sizeanalysis_details.png) - - -# ESP-IDF Terminal - -This would launch a local terminal with all the environment variables which are set under `Preferences` > `C/C++` > `Build` > `Environment`. The default working directory would be either the currently selected project or IDF_PATH if there is no project selected. - -The terminal PATH is also configured with `esptool`, `espcoredump`, `partition_table`, and `app_update` component paths so that it will be handy to access them directly from the ESP-IDF terminal. - -To launch the ESP-IDF Terminal: - -* Click on the `Open a Terminal` icon from the toolbar. -* Choose `ESP-IDF Terminal` from the terminal drop-down and click `OK` to launch a terminal. - -![](docs_readme/images/idf_terminal.png) - - -# Installing ESP-IDF Components - -You can install the ESP-IDF Components directly into your project from the available components online. Follow the steps below: - -* Right-click on the project from `Project Explorer` in which you want to add the component to and Select `Install ESP-IDF Components`. - - ![](docs_readme/images/ESP-IDF_Components/install_components.png) - - A new window will open up showing all the available component to be installed. - -* From the window, you can click on `Install` button to add that component to the project. To get to the readme file for that component you can click on `More Info` which will open the browser link to the readme file of that component. - ![](docs_readme/images/ESP-IDF_Components/components_window.png) - -Already added components are also shown but the `Install` button changes text to `Already Added` and is disabled. - - -# Configuring Environment Variables - -All the required environment variables are automatically configured by the IDE during the ESP-IDF and Tools installation process (Espressif > ESP-IDF Manager > Add ESP-IDF). You can verify them in the Preferences page under `C/C++` > `Build` > `Environment`. - -![](docs_readme/images/2_environment_pref.png) - -# Configuring Toolchains - -We need to tell Eclipse CDT what core build toolchain and CMake toolchain to use to build the project. However, this will be auto-detected if you've installed the tools using the `Espressif` > `ESP-IDF Manager` > `Add ESP-IDF` option from IDE. - -If these toolchains are not detected for any reason, please follow the step-by-step instructions below to add a new toolchain. - - -# Configuring Core Build Toolchains - -1. Open Eclipse Preferences. -1. Navigate to `C/C++` > `Core Build Toolchains` preference page. -1. Click on `Add..` from the user-defined toolchains tables. -1. Select `GCC` as a toolchain type. -1. Click on `Next`. -1.

Below is a description of how to fix the most common build issue on the current ESP-IDF master (ESP-IDF v5.1-dev-992-gaf28c1fa21-dirty). To work around clang build errors please refer to [this](https://github.com/espressif/idf-eclipse-plugin/blob/master/WORKAROUNDS.md#clang-toolchain-buid-errors). - - -# Launch Configuration - -To provide the customized launch configuration and flash arguments, please follow the step-by-step instructions below. - -1. Click on the `Launch Configuration` edit button. -1. Switch to the `Main` tab. -1. Specify the `Location` where this application has to run. Since `idf.py` is a Python file, will configure the Python system path. Example:`${system_path:python}`. -1. Specify the `Working directory` of the application. Example: `${workspace_loc:/hello_world}`. -1. In additional arguments, provide a flashing command which will run in the specified working directory. -1.

The ESP-IDF Eclipse plugin provides a hint viewer where you can type an error message and find a hint for it. -Prerequisites for it is to have `hints.yml`, which is available from ESP-IDF v5.0 and higher. If you are using lower versions of ESP-IDF, you can still use the hints viewer. To do it, you have to manually download the hints.yml file from [here](https://github.com/espressif/esp-idf/blob/master/tools/idf_py_actions/hints.yml) and put it to your `esp-idf/tools/idf_py_actions/` path. To download a file from GitHub, right-click the `Raw` button and then `Save as...`. - -To open the hints viewer go to `Windows` -> `Show View` -> `Other...` -> `Espressif` -> `Hints`.

Launch the `sdkconfig` in project root by double-clicking on it which will open the configuration editor. -![](docs_readme/images/GDBStubDebugging/sdkconfig_editor.png) - -1. Expand the `Component Config` section and select `ESP System Settings`. From the settings on the right for `Panic Handler behaviour` select the `GDBStub on Panic option` from the list. -![](docs_readme/images/GDBStubDebugging/sdkconfig_editor_panic_behavior.png) - -Now you will be taken to the GDBStub debugger automatically when you connect the serial monitor and there is a panic for this example. - -To use the GDBStub debugging for a project: - -1. Create a template `hello_world` project and add the following lines in the main c file. - - ``` - This is a global variable
- COREDUMP_DRAM_ATTR uint8_t global_var; - ``` - -1. Now add these two lines just above the `esp_restart()` function - - ``` - global_var = 25; - assert(0); - ``` - -The final file should be something like this: -![](docs_readme/images/GDBStubDebugging/code_example.png) - -Build and flash the project and launch the serial monitor. On line number 45, we are signaling for a failing assert which will put the chip in panic mode and when that line reaches, you will be prompted to switch the perspective to debug mode and the chip will be halted. - -Remember that this is a panic mode and you cannot continue the execution from here, you will have to stop and restart the chip through IDF commands or simply restart the serial monitor. - -![](docs_readme/images/GDBStubDebugging/debug_panic_mode.png) - -You can view the registers stack trace and even view the value of variables in the stack frame. - -To exit the debug session simply press `stop` button. - - - -# Core Dump Debugging - -The IDF-Eclipse plugin allows you to debug the core dump if any crash occurs on the chip and the configurations are set. Currently only the UART core dump capture and debugging is supported. - -To enable core dump debugging for a project: - -1. You need to enable it first in `sdkconfig`. Launch the `sdkconfig` in the project root by double-clicking on it which will open the configuration editor - -1. Click on the `Core Dump` from the settings on the left and select `Data Destination` as `UART`. -![](docs_readme/images/CoreDumpDebugging/sdkconfig_editor.png) - -This will enable the core dump debugging and whenever you connect a serial monitor for that project if any crash occurs it will load the dump and open a debug perspective in Eclipse to let you diagnose the dump where you can view all the information in the core dump. - -You can view the registers stack trace and even view the value of variables in stack frame. - -To exit the debug session: simply press stop button. - - -# Device Firmware Upgrade (DFU) through USB - -Device Firmware Upgrade (DFU) is a mechanism for upgrading the firmware of devices through Universal Serial Bus (USB). There are a few requirements that need to be met: - -- DFU is supported by ESP32-S2 and ESP32-S3 chips. -- You will need to do some electrical connection work (Here is a [guide](https://blog.espressif.com/dfu-using-the-native-usb-on-esp32-s2-for-flashing-the-firmware-b2c4af3335f1) for the ESP32-S2 board). The necessary connections for the USB peripheral are shown in the following table. - -| GPIO | USB | -| -----| ------------| -| 20 | D+ (green) | -| 19 | D- (white) | -| GND | GND (black)| -| +5V | +5V (red) | - -After meeting the above requirements: - -1. The chip needs to be in bootloader mode for the detection as a DFU device and flashing. This can be achieved by pulling GPIO0 down (e.g. pressing the BOOT button), pulsing RESET down for a moment and releasing GPIO0. - -1. Install USB drivers (Windows only). The drivers can be installed by the [Zadig tool](https://zadig.akeo.ie/). - - Please make sure that the device is in download mode before running the tool and that it detects the device before installing the drivers. - - The Zadig tool might detect several USB interfaces of the target. Please install the WinUSB driver for only that interface for which there is no driver installed (probably it is Interface 2) and don't re-install the driver for the other interface. - - The manual installation of the driver in Device Manager of Windows is not recommended because the flashing might not work properly. - -After meeting the above requirements, you are free to build and flash via DFU. How to use DFU: - -1. Edit the active launch configuration. -1. In the main tab, select the `Flash over DFU` option. -1. Select a suitable IDF target for DFU -1. Now, if you use the build command, an extra file (dfu.bin) will be created, which can be used later for flashing. - -![DFU actions](https://user-images.githubusercontent.com/24419842/226182180-286099d3-9c1c-4394-abb0-212d43054529.png) - -Additional information, including common errors and known issues, is mentioned in this [guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-guides/dfu.html#usb-drivers-windows-only). - - -# Application Level Tracing - -ESP-IDF provides a useful feature for program behavior analysis called [Application Level Tracing](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-guides/app_trace.html?). IDF-Eclipse plugin has UI, that allows the use of start, and stop tracing commands and process received data. To familiarize yourself with this library, you can use the [app_trace_to_host](https://github.com/espressif/esp-idf/tree/release/v5.0/examples/system/app_trace_to_host) project or the [app_trace_basic](https://github.com/espressif/esp-idf/tree/release/v5.1/examples/system/app_trace_basic) project if you are using esp-idf 5.1 and higher. These projects can be created from the plugin itself: -![](docs_readme/images/AppLvlTracing_1.png) - -Before you start using application-level tracing, it is important to create a debug configuration for the project where you must select the board you are using in order to successfully start the OpenOCD server. - -![](docs_readme/images/AppLvlTracing_3.png) - -After the debug configuration is created, right-click on the project in the Project Explorer and click on `ESP-IDF` > `Application Level Tracing`: - -![](docs_readme/images/AppLvlTracing_2.png) - -It can take a while to open the application level tracing dialog because the OpenOCD server starts first, so you don't need to start it externally. At the very top of the application-level trace dialog, there are auto-configured fields that you can change for the trace start command. - -Start command: - -* Syntax: `start [poll_period [trace_size [stop_tmo [wait4halt [skip_size]]]]` -* Argument: - * `outfile`: Path to file to save data from both CPUs. This argument should have the following format: ``file://path/to/file``. - * `poll_period`: Data polling period (in ms) for available trace data. If greater than 0 then command runs in non-blocking mode. By default, 1 ms. - * `trace_size`: Maximum size of data to collect (in bytes). Tracing is stopped after specified amount of data is received. By default -1 (trace size stop trigger is disabled). - * `stop_tmo`: Idle timeout (in sec). Tracing is stopped if there is no data for a specified period of time. By default -1 (disable this stop trigger). Optionally set it to a value longer than the longest pause between tracing commands from the target. - * `wait4halt`: If 0 start tracing immediately, otherwise command waits for the target to be halted (after reset, by breakpoint etc.) and then automatically resumes it and starts tracing. By default, 0. - * `skip_size`: Number of bytes to skip at the start. By default, 0. - -Additional information can be found [here](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-guides/app_trace.html?). - -![](docs_readme/images/AppLvlTracing_4.png) - -The next two fields `Trace Processing Script` and `Start Parsing Command` are used to parse the output file. - -* `Trace Processing Script` is used to provide the path to the parsing script, by default it is logtrace_proc.py from esp-idf. -* `Start Parsing Command` allows you to check the resulting parsing command and edit it if it's necessary. By default, this field is automatically configured to match `$IDF_PATH/tools/esp_app_trace/logtrace_proc.py/path/to/trace/file/path/to/program/elf/file`. - -Note the `Start parse` button is disabled until a dump file is available. To generate it, click the `Start` button at the bottom of the dialog box. After you click, the button changes to Stop so that you can stop tracking. - -When the output file is generated, you can click on `Start parse` button, and you will see the parsed script output in the Eclipse console: - -![](docs_readme/images/AppLvlTracing_5.png) - - -# Partition Table Editor UI for ESP-IDF - -The Partition Table Editor command allows you to edit your [partition table](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/partition-tables.html) in a more convenient way, where you can see the supported types and subtypes and monitor the correctness of the entered data. - -Steps: - -1.
