Felipe Neves a3c90bf59a freertos: merged freertos 10 kernel files into IDF
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) examples
  • ethernet 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, see protocols 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.
