# Pthread Example
|
||
|
|
||
|
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||
|
|
||
|
ESP-IDF provides implementations for many standard POSIX Threads (pthread) APIs. These APIs are impmlemented as thin wrappers around FreeRTOS APIs.
|
||
|
|
||
|
This example demonstrates how to create threads using this API, and how to use the ESP-IDF pthreads extension API to set default thread parameters for the related FreeRTOS tasks. For complete details about supported Pthreads APIs, consult the ESP-IDF Programmers Guide.
|

|
|
||
|
## How to use example
|
||
|
|
||
|
### Hardware Required
|
||
|
|
||
|
This example should be able to run on any supported Espressif SoC development board.
|
||
|
|
||
|
### Configure the project
|
||
|
|
||
|
```
|
||
|
idf.py set-target esp32
|
||
|
```
|
||
|
|
||
|
(Replace `esp32` with the name of the chip target you are using.)
|
||
|
|
||
|
```
|
||
|
idf.py menuconfig
|
||
|
```
|
||
|
|
||
|
### Build and Flash
|
||
|
|
||
|
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||
|
|
||
|
```
|
||
|
idf.py -p PORT flash monitor
|
||
|
```
|
||
|
|
||
|
(Replace PORT with the name of the serial port to use.)
|
||
|
|
||
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
||
|
|
||
|
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
