Espressif IoT Development Framework
ESP-IDF is the official development framework for the ESP32 chip.
Developing With ESP-IDF
Setting Up ESP-IDF
See setup guides for detailed instructions to set up the ESP-IDF:
- Getting Started Guide for the stable ESP-IDF version
- Getting Started Guide for the latest (master branch) ESP-IDF version
Non-GitHub forks
ESP-IDF uses relative locations as its submodules URLs (.gitmodules). So they link to GitHub.
If ESP-IDF is forked to a Git repository which is not on GitHub, you will need to run the script
tools/set-submodules-to-github.sh after git clone.
The script sets absolute URLs for all submodules, allowing git submodule update --init --recursive
to complete.
If cloning ESP-IDF from GitHub, this step is not needed.
Finding a Project
As well as the esp-idf-template project mentioned in Getting Started, ESP-IDF comes with some example projects in the examples directory.
Once you've found the project you want to work with, change to its directory and you can configure and build it.
To start your own project based on an example, copy the example project directory outside of the ESP-IDF directory.
Quick Reference
See the Getting Started guide links above for a detailed setup guide. This is a quick reference for common commands when working with ESP-IDF projects:
Setup Build Environment
(See Getting Started guide for a full list of required steps with details.)
- Install host build dependencies mentioned in Getting Started guide.
- Add
tools/
directory to the PATH - Run
python -m pip install -r requirements.txt
to install Python dependencies
Configuring the Project
idf.py menuconfig
- Opens a text-based configuration menu for the project.
- Use up & down arrow keys to navigate the menu.
- Use Enter key to go into a submenu, Escape key to go out or to exit.
- Type
?
to see a help screen. Enter key exits the help screen. - Use Space key, or
Y
andN
keys to enable (Yes) and disable (No) configuration items with checkboxes "[*]
" - Pressing
?
while highlighting a configuration item displays help about that item. - Type
/
to search the configuration items.
Once done configuring, press Escape multiple times to exit and say "Yes" to save the new configuration when prompted.
Compiling the Project
idf.py build
... will compile app, bootloader and generate a partition table based on the config.
Flashing the Project
When the build finishes, it will print a command line to use esptool.py to flash the chip. However you can also do this automatically by running:
idf.py -p PORT flash
Replace PORT with the name of your serial port (like COM3
on Windows, /dev/ttyUSB0
on Linux, or /dev/cu.usbserial-X
on MacOS. If the -p
option is left out, idf.py flash
will try to flash the first available serial port.
This will flash the entire project (app, bootloader and partition table) to a new chip. The settings for serial port flashing can be configured with idf.py menuconfig
.
You don't need to run idf.py build
before running idf.py flash
, idf.py flash
will automatically rebuild anything which needs it.
Viewing Serial Output
The idf.py monitor
target uses the idf_monitor tool to display serial output from the ESP32. idf_monitor also has a range of features to decode crash output and interact with the device. Check the documentation page for details.
Exit the monitor by typing Ctrl-].
To build, flash and monitor output in one pass, you can run:
idf.py flash monitor
Compiling & Flashing Only the App
After the initial flash, you may just want to build and flash just your app, not the bootloader and partition table:
idf.py app
- build just the app.idf.py app-flash
- flash just the app.
idf.py app-flash
will automatically rebuild the app if any source files have changed.
(In normal development there's no downside to reflashing the bootloader and partition table each time, if they haven't changed.)
Erasing Flash
The idf.py flash
target does not erase the entire flash contents. However it is sometimes useful to set the device back to a totally erased state, particularly when making partition table changes or OTA app updates. To erase the entire flash, run idf.py erase_flash
.
This can be combined with other targets, ie idf.py -p PORT erase_flash flash
will erase everything and then re-flash the new app, bootloader and partition table.
