Qt Creator integration#

This tutorial shows how to adapt the Qt Creator IDE for comfortable developing and debugging of xpcc projects on STM32 microcontrollers.

This tutorial uses xpcc’s hello-world example project of our getting-started-with-xpcc repository for the STM32F4 Discovery board.

Installation#

Install Qt Creator version 4.0 or above.

# On Fedora 22 and up
sudo dnf install qtcreator
# On OS X
brew cask install qtcreator

Global setup#

Enable Bare Metal plugin#

OS X: Qt CreatorAbout Plugins...
Linux: HelpAbout Plugins...

Enable BareMetal plugin

Enable the BareMetal plugin and restart Qt Creator.

Code Style#

OS X: Qt CreatorPreferences...
Linux: Go to Options dialog: ToolsOptions...

Go to Tab C++, create a copy of the Qt [builtin] code style, name it xpcc and click Edit....

Code Style
Set Tab policy to Tabs only, save and exit.

Add debugger#

In Build & Run and sub-tab Debuggers click Add to add the arm-none-eabi-gdb debugger to Qt Creator:

Create new arm-none-eabi-gdb debugger
Qt Creator requires the debugger to support Python scripting. If you use the precompiled arm-none-eabi toolchain from ARM you need to use arm-none-eabi-gdb-py here!

For Linux distributions that ship the toolchain themselves and have Python scripting enabled by default, you can use /usr/bin/arm-none-eabi-gdb (without the -py).

Add OpenOCD server#

Go to tab Bare Metal and select AddOpenOCD.

OpenOCD GDB server provider settings

Use the following settings:

  • Startup mode: Startup in TCP/IP Mode
  • Executable file: Path to OpenOCD binary: /usr/local/bin/openocd (OS X), or /usr/bin/openocd (Linux)
  • Root scripts directory: Absolute path to OpenOCD script directory: /usr/local/share/openocd/scripts (OS X), or /usr/share/openocd/scripts (Linux)
  • Configuration File: board/stm32f4discovery.cfg

If you want to use other targets, create an OpenOCD provider, Device and Kit for each or them. Have a look at the OpenOCD script directory to find a configuration file for your target.

Add target device#

For the next step go to the Devices tab and Add... a new Bare Metal Device. Use the following settings:

Qt Creator device settings
Again, go to tab Build & Run, sub-tab Kits and click Add to add a new so called Kit.
Settings for the STM32F4-DISCO Kit

  • Device type: Bare Metal Device
  • Device: STM32F4-DISCO (the device we just created)
  • Compiler: Irrelevant, we won't use it.
  • Debugger: arm-none-eabi-gdb
  • Qt version: None

Click Ok.

xpcc project setup#

Check out the getting started repository:

git clone --recursive https://github.com/roboterclubaachen/getting-started-with-xpcc.git

Change to the project folder and run scons qtcreator to generate the Qt creator project files for the xpcc project:

cd getting-started-with-xpcc/hello-world
scons qtcreator

scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
Template: 'getting-started-with-xpcc/xpcc/templates/qtcreator/project.creator.in' to 'hello-world.creator'
Template: 'getting-started-with-xpcc/xpcc/templates/qtcreator/project.config.in' to 'hello-world.config'
Template: 'getting-started-with-xpcc/xpcc/templates/qtcreator/project.files.in' to 'hello-world.files'
Template: 'getting-started-with-xpcc/xpcc/templates/qtcreator/project.includes.in' to 'hello-world.includes'
scons: done building targets.

Open project with Qt Creator: FileOpen File or Project

Select *.creator file
The view should be like this
Select the Projects view from the Mode Selector on the left side (WindowShow Mode Selector if not visible).

First, click Add KitSTM32F4-DISCO, then remove the created Default using the icon to the right of it: DefaultRemove Kit.

Remove the desktop kit

Next go to the Build Settings and remove all existing Build Steps and Clean Steps and:

  • add a new Custom Process Step build step with command scons and argument program.
  • add a new Custom Process Step clean step with command scons and argument -c.
  • add a custom PATH to the System Environment, if you need to.

Qt Creator project build settings
Switch to Run Settings and select Run on GDB server or hardware debugger as Run Configuration. Select the *.elf-file as executable.

Congratulations, you can now compile, program and debug your xpcc application comfortably in Qt Creator.
