check master read write functions with array of registers) fix master serial processing code and modbus controller to work with register array modbus_master: add reading and writing of test value array (58 registers) to check failure is gone remove parameter temporary buffer from modbus controller to allow more than 24 byte writes driver: fix issue with TOUT feature driver: fix uart_rx_timeout issue driver: fix issue with rxfifo_tout_int_raw not triggered when received fifo_len = 120 byte and all bytes read out of fifo as result of rxfifo_full_int_raw driver: add function uart_internal_set_always_rx_timeout() to always handle tout interrupt examples: call uart_internal_set_always_rx_timeout() to handle tout interrupt correctly examples: update examples to use tout feature driver: reflect changes of uart_set_always_rx_timeout() function, change uart.c driver: change conditions to trigger workaround for tout feature in uart.c driver: change uart_set_always_rx_timeout() freemodbus: fix tabs, remove commented code driver: remove uart_ll_is_rx_idle() |

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.
