STM32CubeIDE

Installation

Linux

Last release of STM32CubeIDE can be obtained here: https://www.st.com/en/development-tools/stm32cubeide.html.
For Debian like distributions (e.g. ubuntu), download the STM32CubeIDE-DEB file. To download it, you will need to provide name and a valid email address.

Unzip the file (e.g. <FILE> = en.st-stm32cubeide_1.0.1_3139_20190612_1256_amd64.deb_bundle) 

unzip <FILE>.sh.zip

It will generate a .sh file. Give it permits for execution. 

chmod 777 <FILE>.sh

Finally, execute the installation 

sudo ./<FILE>.sh

You must accept all license agreements.


Windows

Last release of STM32CubeIDE can be obtained here: https://www.st.com/en/development-tools/stm32cubeide.html.
For Windows like distributions, download the STM32CubeIDE-Win file. To download it, you will need to provide name and a valid email address.

Unzip the file and execute the binary. Follow all steps and accept all conditions.

MAC

Last release of STM32CubeIDE can be obtained here: https://www.st.com/en/development-tools/stm32cubeide.html.
For MAC like distributions, download the STM32CubeIDE-MAC file. To download it, you will need to provide name and a valid email address.

Unzip the file and execute the binary. Follow all steps and accept all conditions.

IMPORTANT Some problems have been reported related to lasts versions of STM32CubeIDE-MAC, where the code generator does not include macro definitions for the peripheral of nucleo-boards. Last version correctly tested is 1.0.0.

Hello World

In this Section a Hellow World (led blinking) example will be programmed on a NUCLEO-F446RE board:

  • Open STM32CubeIDE
  • Select where to store the workspace. This will be the folder where different projects could be stored.
  • Select Start new STM32 project
  • A microcontroller or board should be selected. In our case, a NUCLEO-F446RE will be used. Then, select board selector and search part number Nucleo-F446RE . Once chosen, press Next
  • Chose a Project name (e.g. ledp) and keep the rest of parameters as they are. Press Finish
  • The STM32CubeIDE will ask if you want Initialize all peripherals with their default Mode. Answer Yes
  • The STM32CubeIDE will inform that yhis kind of projects is associated with the STM32CubeMx prespective and will ask if you want to open this perspective now. Answer Yes .
    Download of required libraries will start. It could take long for the first time depending on your connection settings.
  • Once the project is open, on the left side on the "Project Explorer", look for Src -> main.c .
    Inside the code, look for the while(1) sentence in the main(void) function, and fill it as follows: 
    while (1)
{
  HAL_GPIO_TogglePin(LD2_GPIO_Port, LD2_Pin);
  HAL_Delay(100);
 /* USER CODE END WHILE */

 /* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
  • In order to compile, Go to Project -> Build All (Ctrl+B or Hammer) . It should compile the code without errors.
    If any error appears, previous steps should be reviewed.
  • In order to start the debugger, Go to Run -> Debug (F11 or bug)
    Select STM32 MCU C/C++ Application and Press OK
  • Leave all configuration propeties as they are and Press OK
  • The STM32CubeIDE will ask if you want to switch to the debug perspective say Switch
  • In order to execute the code, Go to Run -> Resume (F8 or Green Arrow) .
    The led should be blinking at 100 ms.

Problems with STM32CUBEIDE

sprintf %f

All the information on this page is obtained from: http://www.nadler.com/embedded/newlibAndFreeRTOS.html There is some errors on the implementation of malloc on STM32CubeMX, so if using some newlib fuctions (e.g. sprintf %f), the following steps must be implemented:

  • Remove heapX.c form Middlewares->Thirs_Party->FreeRTOS->Source->CMSIS_RTOS_V2->portable->MemMang->heap_X.c
  • Add this file to the Src directory: heap_useNewlib and rename it as heap_useNewlib.c
  • Comment _sbrk function on sysmem.c file; it is already implemented on heap_useNewlib.c
  • Include in FreeRTOSConfig.h the folowing directive: 
    • #define configUSE_NEWLIB_REENTRANT 1
  • Go to Project -> Porperties -> MCU Settings -> Tool Settings and select float for printf and scanf from newlib-nano

IDE Flickering

First check the value of GTK_IM_MODULE in your environment by executing 

echo $GTK_IM_MODULE

If the output is "xim", Eclipse expects it to be “ibus”. So enter the following command in a terminal session to set it to the value. 

export GTK_IM_MODULE="ibus"

Now if you launch Eclipse from the same terminal session, you should not experience any flickering issue. If you launch eclipse from a desktop menu entry, then edit the .desktop file (e.g. /usr/share/applications/st-stm32cubeide-1.6.1.desktop) and put the following string in the beginning of the Exec command: 

env GTK_IM_MODULE=ibus

E.g. Exec=env GTK_IM_MODULE=ibus /opt/st/stm32cubeide_1.6.1/stm32cubeide %F
