The ESP-IDF is the SDK, provided by Expressif, for programming the ESP32 with C and C++.
Ensure you are a member of the
uucpgroup so that you have serial access, usingusermod -a -G uucp $USER
Installation
yay -Sy esp-idf
Pre-requisites:
To use ESP-IDF:
1. Run /opt/esp-idf/install.sh to install ESP-IDF to ~/.espressif.
You only have to do this once after installing or upgrading
the esp-idf package.
2. Run `source /opt/esp-idf/export.sh` to add idf.py and idf_tools.py
to your current PATH. You will have to do this in every terminal
where you want to use ESP-IDF. Alternatively, you can add
"source /opt/esp-idf/export.sh" to ~/.bashrc or the equivalent for
your shell to load ESP-IDF automatically in all terminals.
Must run
. /opt/esp-idf/export.sh
In any terminal where you want to compile to the device.
Compilation process
To demonstrate compilation, I have copied one of the demo projects provided:
cp -r /opt/esp-idf/examples/get-started/hello_world .
To initialise the project, run:
idf.py set-target esp32
Python is used as the client for automated processes/bootstrapping etc, even though the code that runs on the device is written in C.
