freertos/port: update the port files and split into xtensa and riscv ports freertos: separated cpu files from rest of the kernel sources freertos/port_xtensa: separated private include files into a folder freertos/tasks: added task create pinned to core function do not break current IDF API freertos/tasks: mimiced task create pinned function into tasks.c to do not break the IDF API. freertos: freertos component now compiling freertos: freertos component now building freertos: moved critical sections outside from FR kernel section to portable section portmacro_xtensa: add void indentifier on functions that take no arguments freertos: fix critical sections implementation to match with their function prototype freertos: add cmake changes of freertos into make freertos: remove portDONT_DISCARD attribute from switch context function, it was breaking the docs building. freertos: fix conflicitng types of vApplicationSleep function license: update the license of freertos freertos: Doxygen comments refactored to render them correctly on docs freertos: added new functions of freertos into the documentation freertos: added message buffers and stream buffers to documentation sysview: update freertos system view to the compatible with version 10 freertos: fixed event group documentation rendering freertos: update static task structure to match the actual tcb size freertos: removed backported test functions freertos/smp: brought SMP code to FreeRTOS 10 port freertos/portmacro: added missing crosscore interrupt for yielding tasks freertos: replaced soft-critical sections with hard-critical sections used by SMP freertos: placed muxes inside of kernel objects freertos: replaced original FR critical sections with SMP enabled spinlocks critical sections freertos: moved xtensa port files to a separated folder freertos: added multiple instance of global variables required to SMP freertos: added SMP modifications on specific tasks module functions freertos: added TLS deletion function to task module freertos/tls: initialize TLS deletion callback to avoid crashing when calling task delete freertos: modified vTaskDelete to do not erase current task that runs on other core freertos: reverted taskhandle and timerhandle as void* type freertos: fixed de-referencing void pointer to get run time counter freertos: fix system view trace enter macro arguments freertos: Replaced soft critical sections with spinlocks on event_groups freertos: fixed tick function to avoid calling tick hooks twice freertos: Nofity give checking per CPU if schedule is suspended freertos: added mpu release on TCB deletion freertos: Added SMP changes when deleting a TCB on idle task freertos/license: update freertos license in COPYRIGHT.rst freertos: unicore configurations can use task create pinned to core, it will be always pinned to core 0 freertos/portmacro: added cpu_hal_get_core_id() function instead of inline assembly freertos/xtensa: update xtensa specific files used in master branch newlib/locks: revert the preemption checking in lock acquisition and release ref_clock: fix initial state of ref_clock interrupt handler freertos: added missing critical sections and yielding checkings freertos: remove magic numbers in vTaskDelete freertos: added missing critical section in prvIsQueueEmpty |

Examples
This directory contains a range of example ESP-IDF projects. These are intended to demonstrate parts of ESP-IDF functionality, and to provide code that you can copy and adapt into your own projects.
Example Layout
The examples are grouped into subdirectories by category. Each category directory contains one or more example projects:
bluetooth/bluedroid
contains Classic BT, BLE and coex examples using default Bluedroid host stack.bluetooth/nimble
contains BLE examples using NimBLE host stack.bluetooth/esp_ble_mesh
contains ESP BLE Mesh examples.bluetooth/hci
contains HCI transport (VHCI and HCI UART) examplesethernet
contains Ethernet examples.get-started
contains some very simple examples with minimal functionality.mesh
contains Wi-Fi Mesh examples.peripherals
contains examples showing driver functionality for the various onboard ESP32 peripherals.protocols
contains examples showing network protocol interactions.storage
contains examples showing data storage methods using SPI flash or external storage like the SD/MMC interface.system
contains examples which demonstrate some internal chip features, or debugging & development tools.wifi
contains examples of advanced Wi-Fi features. (For network protocol examples, seeprotocols
instead.)build_system
contains examples of build system features
Using Examples
Building an example is the same as building any other project:
- Follow the Getting Started instructions which include building the "Hello World" example.
- Change into the directory of the new example you'd like to build.
- Run
idf.py menuconfig
to open the project configuration menu. Most examples have a project-specific "Example Configuration" section here (for example, to set the WiFi SSID & password to use). idf.py build
to build the example.- Follow the printed instructions to flash, or run
idf.py -p PORT flash
.
Copying Examples
Each example is a standalone project. The examples do not have to be inside the esp-idf directory. You can copy an example directory to anywhere on your computer in order to make a copy that you can modify and work with.
The IDF_PATH
environment variable is the only thing that connects the example to the rest of ESP-IDF.
If you're looking for a more bare-bones project to start from, try esp-idf-template.
Contributing Examples
If you have a new example you think we'd like, please consider sending it to us as a Pull Request.
In the ESP-IDF documentation, you can find a "Creating Examples" page which lays out the steps to creating a top quality example.
