# Build and Develop the project using VS Code
|
|
|
|
The .VS Code folder contains configuration files for developing InfiniTime with VS Code. Effort was made to have these rely on Environment variables instead of hardcoded paths.
|
|
|
|
## Environment Setup
|
|
|
|
To support as many setups as possible the VS Code configuration files expect there to be certain environment variables to be set.
|
|
|
|
Variable | Description | Example
|
|
----------|-------------|--------
|
|
**ARM_NONE_EABI_TOOLCHAIN_PATH**|path to the toolchain directory|`export ARM_NONE_EABI_TOOLCHAIN_PATH=/opt/gcc-arm-none-eabi-10.3-2021.10`
|
|
**NRF5_SDK_PATH**|path to the NRF52 SDK|`export NRF5_SDK_PATH=/opt/nRF5_SDK_15.3.0_59ac345`
|

## VS Code Extensions
|
|
|
|
We leverage a few VS Code extensions for ease of development.
|
|
|
|
#### Required Extensions
|
|
|
|
- [C/C++](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools) - C/C++ IntelliSense, debugging, and code browsing.
|
|
- [CMake Tools](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cmake-tools) - Extended CMake support in Visual Studio Code
|
|
|
|
#### Optional Extensions
|
|
|
|
[Cortex-Debug](https://marketplace.visualstudio.com/items?itemName=marus25.cortex-debug) - ARM Cortex-M GDB Debugger support for VS Code
|
|
|
|
Cortex-Debug is only required for interactive debugging using VS Codes built in GDB support.
|
|
|
|
## VS Code/Docker DevContainer
|
|
|
|
The .devcontainer folder contains the configuration and scripts for using a Docker dev container for building InfiniTime
|
|
|
|
Using the [Remote-Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension is recommended. It will handle configuring the Docker virtual machine and setting everything up.
|
|
|
|
More documentation is available in the [readme in .devcontainer](../.devcontainer/README.md)
|
|
|
|
### DevContainer on Ubuntu
|
|
|
|
To use the DevContainer configuration on Ubuntu based systems two changes need to be made:
|
|
|
|
1. Modify the file `.devcontainer/devcontainer.json` and add the argument `"--net=host"` to the `"runArgs"` parameter making the line look like this:
|
|
`"runArgs": [ "--cap-add=SYS_PTRACE", "--security-opt", "seccomp=unconfined", "--net=host"],`
|
|
2. Modify the file `.vscode/launch.json` and change the argument of `"gdbTarget"` to `"127.0.0.1:3333"`, making the line look like:
|
|
`"gdbTarget": "127.0.0.1:3333",`
|
|
3. To start debugging launch openocd on your host system with the appropriate configuration, for example with a stlink-v2 the command is:
|
|
`openocd -f interface/stlink.cfg -f target/nrf52.cfg`. This launches openocd with the default ports `3333`, `4444` and `6666`.
|
|
4. In VsCode go to the Debug pane on the left of the screen and select the configuration `Debug - Openocd docker Remote` and hit the play button on the left.
