STM32 Nucleo microcontroller Profile for IBM Rational Rhapsody

2. In Project menu > Settings, confirm the Firmware Download Location at the bottom of the window. Uncheck the default option if you wish. 

3. Press OK to close the window. You should be prompted to download the firmware at this point.
 

Select YES.

The firmware will now download. This can take a few minutes.

Note you can also download this manually from the ST website - https://www.st.com/en/embedded-software/stm32cube-mcu-packages.html?querycriteria=productId=LN1897  - but you must download the correct package for your microcontroller family.

4. Generate the code using Project menu > Generate code. Close STMCubeMX when completed.

5.  Run the Start Menu > IBM Rational > ImportCubeMX application.


6. Enter information into the fields so that they are validated: OK

- Truestudio IDE: This is the installation of the Truestudio IDE installed in the prerequisites.
- CubeMX project: This is the folder containing the  .ioc STM32CubeMX project file used in step 1.
- BSP Definitions: This is the Drivers\BSP\STM32xxxx_Nucleo directory downloaded in step 3.  For example:
   C:\Users\chris\STM32Cube\Repository\STM32Cube_FW_F1_V1.6.1\Drivers\BSP\STM32F1xx_Nucleo
- Nucleo Development Kit: Select the version to match your development kit
- Rhapsody Project type: This is the framework that the resulting Rhapsody project will use.
- Rhapsody Project Name: This is the name that the resulting Rhapsody project will use.
- Rhapsody Project Path: This is the directory where the resulting Rhapsody project will reside.

7. Press import. When it completes you will be prompted to open the project in Rhapsody. Select this option.

8.  When the project loads ensure that the following message appears in the output window:

If this does not appear, close Rhapsody and close all other Rhapsody processes (check process explorer)

9. Located the STM32ImportPkg > stm32xxxx_it file and add the following code to the TIM1_UP_TIM16_IRQHandler() function:
 

static uint32_t counter = 0;
if (counter >= 50)
{
HAL_GPIO_TogglePin(LED2_GPIO_Port, LED2_Pin);
counter = 0;
}
counter++;

10. This step is different depending on which Rhapsody framework was selected:

For a "No Framework" (NOF) Project:

- Locate the STM32ImportPkg > main file and add the following code to the main function:

HAL_TIM_Base_Start_IT(&htim1);

For an Interrupt-Driven Framework (IDF) Project:

- Locate the STM32ImportPkg > stm32_main file and add the following code to the stm32_setup function:

HAL_TIM_Base_Start_IT(&htim1);

For a MicroC (MXF) Project:

- Locate the STM32ImportPkg > stm32_main file and add the following code to the stm32_setup() function:

HAL_TIM_Base_Start_IT(&htim1);

- Expand the configuration and run the menu command:  [STM32] Regenerate Configuration
 

11. To generate and build the project, use Code menu > Regenerate and then Code menu > Rebuild.

12. Make sure the STM32 Development kit is connected to the USB port on your computer.

13. To download to the target and run, use the Code menu > Target > Run CubeMXImport.elf.

Creating a CubeMX Timer project

This section shows the steps required to create the STM32Cube TimerBlink example. This is for completeness only. First time users should refer to the Quickstart Guide.

1. Open STM32 CubeMX application

2. New project > Select the device from the support list.

3. In Pinout tab:

• Select Sys > Debug > JTAG (5 pins)

• Select TIM1 > Clock Source > Internal Clock

• In diagram, select PA5 as GPIO_OUTPUT

4. In Configuration tab

• Click GPIO button under System

  • Add user label “LED2”

• Click NVIC button under System

  • Check TIM1 break interrupt, set Preemption Priority to 1

  • Check TIM1 update interrupt, set Preemption Priority to 1

• Click TIM1 button under Control

  • Set Prescaler to 64000 (decimal)

  • Set CounterMode to Down

  • Set Counter Period to 1 (decimal)

5. In Project menu > Settings

• Add project name and location.

• Set Toolchain/IDE to “Makefile”

• Use default Firmware location

• Accept YES if prompted to download the firmware (this should happen if this is the first time you have selected this device.)

6. Project menu > generate code
