mbed build for Atom (via atom-build)

Uses the atom-build package to execute mbed-cli builds in the Atom editor.

Prerequisites

In general a working installation of the mbed-cli is required. For instructions on the setup visit the mbed-cli project page.

The atom-build-mbed package itself requires atom-build e.g. installable through apm from the command line:

apm install build

Optionally (but recommended) to display compile errors and warnings nicely, add the linter package:

apm install linter

Install

Install the mbed builder from the package sources:

apm install build-mbed

Or install from git:

cd $HOME/.atom/packages
git clone https://github.com/wendlers/atom-build-mbed.git build-mbed

Usage

See atom-build for all available key-bindings of the builder.

Triggering / activation of this builder is done by existence of the file mbed_settings.py in the current projects directory.

The builder utilizes the compile sub-command of the mbed-cli described here. Targets exposed by the builder are (select by pressing F7, (re-)execute with F9):

  • mbed: release: perform release build which is the equivalent of mbed compile on the command line.
  • mbed: release (clean build): same as above but with added -c switch to force a full rebuild. The command line equivalent would be mbed compile -c.
  • mbed: debug: use the debugging profile for the build (which adds debug symbols to the binary). This is the same as mbed compile --profile mbed-os/tools/profiles/debug.json on the command line.
  • mbed: debug (clean build): same as above but with added -c switch to force a full rebuild. The command line equivalent would be mbed compile -c --profile mbed-os/tools/profiles/debug.json.
  • mbed: clean: remove the build directory. On the command line this would be done by rm -fr BUILD.

The default target is mbed: release.

You could provide per project targets by creating the file targets.ini alongside the mbed_settings.py script. Each target is defined by [targetname], followed by an entry specifying the parameters which should be passed to mbed:

[fw_one release]
params="--source fw_one --source mbed-os --source common --build BUILD/fw_one"

[fw_one release (debug)]
params="--source fw_one --source mbed-os --source common --build BUILD/fw_one --profile mbed-os/tools/profiles/debug.json"

[fw_two release]
params="--source fw_two --source mbed-os --source common --build BUILD/fw_two"

[fw_two release (debug)]
params="--source fw_two --source mbed-os --source common --build BUILD/fw_two --profile mbed-os/tools/profiles/debug.json"

The above example allows to build two different firmwares (one located in fw_one, the other in fw_two), sharing common parts (here mbed-os and common).

Please note, that when you created a targets.ini initially for your project, you need to advice atom-build to refresh targets with Build: Refresh Targets. Once atom-build is aware of the user targets, they will be refresh automatically every time the targets.ini is saved.

Within the settings dialog of the builder the following could be adjusted:

  • verbosity: depending on the settings, this adds --verbose or --very_verbose to the mbed call.
  • jobs: number of parallel jobs. If > 1, this will add -j <NUM_JOBS> to the mbed call.
  • build dir: if set != default, the output directory will be set to this (instead of using the mbed default which is BUILD). This will add --build <BUILD_DIR> to the mbed call.
  • source dir: if set != default, the source directory will be set to this (instead of using the mbed default which is the current project directory). This will add --source <SOURCE_DIR> to the mbed call.
  • mcu: if set != default, the MCU will be set to this. This will add -m <MCU> to the mbed call.
  • toolchain: if set != default, the toolchain will be set to this. This will add -t <TOOLCHAIN> to the mbed call.
