STM32G431RB NUCLEO Internal Temperature Sensor Channel with Embedded Coder

Hi all,

I followed the Simulink example below.

https://kr.mathworks.com/help/ecoder/stmicroelectronicsstm32f4discovery/ug/STM32F4XX-ADC-example.html

And I found a problem with CubeMX 6.4.0, which is compatible with Embedder Coder Support Package.

When I generated code with CubeMX 6.4.0, the ADC initialization went wrong. (at main.c line 197)

LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_VREFINT);

While I generated code with CubeMX 6.12.1, the ADC initialized well. (at main.c line 197)

LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_VREFINT | LL_ADC_PATH_INTERNAL_TEMPSENSOR);

Due to the lack of temperature path, The measurement of room temperautre was about -90°C with CubeMX 6.4.0.

I couldn't figure out how to run CubeMX 6.12.1 with Embedded Coder.

Is there any way to solve this problem?

MATLAB related version:

- MATLAB 2023a

- Embedded Coder Support Package for ARM Cortex-M Processors V23.1.0

- Embedded Coder Support Package for STMicroelectronics STM32 Processors V23.1.3

STM32 related version:

- STM32CubeMX V.6.4.0

(STM32Cube_FW_G4_V1.5.1)

- STM32CubeMX V.6.12.1

(STM32Cube_FW_G4_V1.6.1)

Also the attached files are Simulink, and CubeMX projects.

Solved by typing the code below at ADC initialization.

/* USER CODE BEGIN ADC1_Init 2 */

LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), LL_ADC_PATH_INTERNAL_VREFINT | LL_ADC_PATH_INTERNAL_TEMPSENSOR);

/* USER CODE END ADC1_Init 2 */

Thanks.
