# Building and flashing
|
|
|
|
1. Make sure you've got all of the submodules in this repo correctly initialised;
|
|
```
|
|
git submodule update --init --recursive
|
|
```
|
|
|
|
2. If this is your first time setting up the repo, then you will need to install
|
|
the ESP-IDF tools. You can consult the [ESP-IDF docs](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/linux-macos-setup.html)
|
|
for more detailed instructions, but the TL;DR is that you'll want to run
|
|
something like this:
|
|
```
|
|
./lib/esp-adf/esp-idf/install.sh esp32
|
|
```
|
|
|
|
3. As a final piece of setup, you will need to source the env file in this repo
|
|
to correctly set up your environment for building.
|
|
```
|
|
. ./.env
|
|
```
|
|
**For VSCode:**
|
|
|
|
When using the Espressif IDF extension, you may want to set the following in your settings.json file:
|
|
```
|
|
"idf.espAdfPath": "${workspaceFolder}/lib/esp-adf",
|
|
"idf.espAdfPathWin": "${workspaceFolder}/lib/esp-adf",
|
|
"idf.espIdfPath": "${workspaceFolder}/lib/esp-adf/esp-idf",
|
|
"idf.espIdfPathWin": "${workspaceFolder}/lib/esp-adf/esp-idf"
|
|
```
|
|
|
|
4. You can now build the project using `idf.py build`. Or to flash the project
|
|
onto your board, something like:
|
|
```
|
|
idf.py -p /dev/ttyUSB0 -b 115200 flash
|
|
```
|
|
(give or take the correct serial port)
|
|
|
|
Remember that you will need to boot your ESP32 into software download mode
|
|
before you will be able to flash.

# Running tests
|
|
|
|
Tests are implemented as a separate application build, located in the `test`
|
|
directory. We use Catch2 as our test framework.
|
|
|
|
To run them, navigate to the test directory, then build and flash as normal.
|
|
Connect to your device via UART, and you will be presented with a terminal
|
|
prompt that you may run tests from.
|
|
|
|
To add new tests to a components, you must:
|
|
1. Create a `test` subcomponent within that component. See `drivers/test` for
|
|
an example of this.
|
|
2. Include the component in the test build and list of testable components, in
|
|
`test/CMakeLists.txt`.

# clangd setup
|
|
|
|
A regular build will generate `build/compile_commands.json`, which clangd will
|
|
automatically pick up. However, there are a couple of additional steps to get
|
|
everything to place nicely.
|
|
|
|
First, you will need to download the xtensa clang toolchain. You can do this
|
|
via ESP-IDF by running `idf_tools.py install xtensa-clang`
|
|
|
|
This will install their prebuild clang into a path like `~/.espressif/tools/xtensa-clang/VERSION/xtensa-esp32-elf-clang/`
|
|
|
|
Next, you will need to configure clangd to use this version of clang, plus
|
|
forcible remove a couple of GCC-specific build flags. Do this by creating
|
|
`.clangd` in the root directory of your project, with contents like so:
|
|
|
|
```
|
|
CompileFlags:
|
|
Add: [
|
|
-ferror-limit=0,
|
|
-I/Users/YOU/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32-elf/include,
|
|
-I/Users/YOU/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32-elf/xtensa-esp32-elf/include,
|
|
-I/Users/YOU/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32-elf/xtensa-esp32-elf/include/c++/8.4.0,
|
|
-I/Users/YOU/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32-elf/xtensa-esp32-elf/include/c++/8.4.0/xtensa-esp32-elf,
|
|
-isysroot=/Users/YOU/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32-elf/xtensa-esp32-elf,
|
|
]
|
|
Remove: [
|
|
-Wduplicated-cond,
|
|
-Wduplicated-branches,
|
|
-Wlogical-op,
|
|
-fno-tree-switch-conversion,
|
|
-mtext-section-literals,
|
|
-mlongcalls,
|
|
-fstrict-volatile-bitfields,
|
|
]
|
|
Compiler: /Users/YOU/.espressif/tools/xtensa-clang/esp-clang/bin/clang++
|
|
```
|
|
|
|
You should then get proper LSP integration via clangd, give or take a couple of
|
|
oddities (e.g. for some reason, my install still can't see `stdio.h`. NBD tho.)
|
|
|
|
Expect this integration to improve sometime in the near future, per [this forum
|
|
thread](https://esp32.com/viewtopic.php?f=13&t=29563).
