STM32CubeMX (MCUs)

I'm using ADC regular and injected channels in STM32G4. I need different oversampling ratio for regular and injected channels, in STM32CubeMX it's possible to configure the oversampling ratio independently for regular and injection channels, but when I took a look at the generated code I saw that the same function has been called for oversampling configuration. It seems like the second function call is overriding the first configuration.Also I've checked on oscilloscope to measure both channels acquisition times. When I'm modifying the parameters of the first function call (which is the oversampling ratio of the regular channels), I see no changes in acquisition time of the regular channels, it's just following the parameters of the second call (injected channels oversampling ratio).I have 2 questions:Why we have configurations for oversampling ratio of both channels in STM32CubeMX, when it's not possible to control them independently?Is there a way to have different ratios other than

Is there a way to prevent CubeMX from constantly messing up the source code formatting?  I spent time setting up the preferences in the CubeIDE tool, but every time CubeMx touches the files, it resets the code formatting.  After the CubeMX returns to the IDE, is there a way to run the IDE source->reformat command?if not possible today, can this be added to the development wish list?thanksMatthew

I would like to use the CAN interface with a CANOPEN library on my STM32F723.As I have found there is a Library for STM chips provided by emotas: https://www.st.com/en/partner-products-and-services/canopen.htmlI have downloaded the Lib on my STM32CubeIDE an now are trying to add it in my CubeMX to the Project: The problem is, it says, its not supporting my MCU. But in the description of the Library it says it should support the F7 chips.Is the library not "free" and I have first to contact emotas or did I forget to install something? Best regards,CO

Hi,I have problem with LTC7106 and STM32G431CBT6.LTC7106 use PMBUS. I never used SMBUS or PMBUS before.I tried to use normal SMBUS implementation and:I can find device (it find 0xC, 0x2A, 0x5A, 0x5B devices. First one is strange but maybe I don’t know something) - the device should have 0x2A address - so I assume that it work properly.I can’t force it to send or receive any data from the device.I tried to do everything as described in: SMBUS/SMBUS_TSENSOR/readme.txt in terms of configuration – but I have no idea what cause the problem.So I have a question – does PMBUS device should be accessible via standard implementation od SMBUS in STM32? I mean should it read and write registers without any problems?To solve the problem I tried to use X-CUBE-SMBUS – I tried to do everything like in: https://community.st.com/t5/stm32-mcus-products/this-is-an-issue-related-to-the-initialization-of-the-x-cube/m-p/751304 and in AN4502But it hang in STACK_SMBUS_Init -> SMBUS_Enable_IRQ -&gt

Hi,I'm trying to configure LevelX using CubeMX.  Does any one know how to link the component driver to LevelX? under file system interfaces, under bsp,The QuadSPI is different from the one listed under bsp, but I included in the project so I can figure out how to write my version.  But I can't seem to figure out how I can define a new driver.  Under LevelX configuration:It says the QSPI component name is MT25TL01G.  How do I change this so I can provide my own driver? 

Dear All,I have created a project where I have placed the APS6408L memory on the HSPI1 peripheral of the STM32U5G9NJH6Q.On CubeMX, I am setting this in the peripheral configuration:And in the memory management tab I see this:I was expecting to see 16MB there.Using this setup my project does not work as the device hard faults when I try to access the second half of the external RAM.Doing this in the configuration:leads to this:And I have tested the code allocating a buffer at the end of the external RAM, playing with it and it works, but I believe that the configuration should be the that of the first image and the result should be that of the second image.Is this an issue of CubeMX?Thanks in advance

Hi,i am using CubeIDE 1.16.1 and if i import the BLE_p2pServer example for NUCLEO-WBA55CG, a few pins (GPIOs for LEDs and buttons) are marked in reset state.Can somebodey explain why they are in reset state and not in GPIO_Input or GPIO_Output?

Hi everyone,I used STM32CubeMX (version 6.11.1) to generate the initialization code for an STM32G491RCT.The toolchain is configured as a Makefile project.At the end of the C_SOURCES definition, it specifies sysmem.c and syscalls.c.# C sources C_SOURCES = \ Core/Src/main.c \ ... Core/Src/sysmem.c \ Core/Src/syscalls.cHowever, those two files were not generated, resulting in the following error:make: *** No rule to make target 'build/sysmem.o', needed by 'build/firmware.elf'. Stop.Is this a bug in STM32CubeMX or am I supposed to implement the functions myself?

I have enable IN1, IN2 and IN5 as ADC inputs. IN1 is called TEMPERATURE. IN2 is called CURRENT and IN5 is called POTENTIOMETER. The DMA is enabled with normal mode and it's called by the Complete Conversion Callback function every time the TIM1 is updated. So, there are also 3 elements in my DMA array. The first element in the DMA array is IN1 and the middle is IN2 and the last one is IN5. In my current situation, IN2 is always zero because there is no voltage at CURRENT (PA1). But sometimes IN1 and IN2 switch position when ADC is sampling data....or DMA switch their place. I don't know. I can see that this occurs sometimes and IN1 gets a zero and IN2 get the same value as IN1 had just before. Thi will occurs once every 15 seconds.Data:Processor: STM32F051R8T6STM32CubeIDE: 1.16.1Firmware: STM32_Cube_FW_F0 V1.11.5Question:How can I take control over the ADC sampling for each element for the DMA? I want to make sure that the ADC scanning the inputs in the correct order and not

Hello,Configuring the I2S on CubeMX on STM32G431, for which I've connected a microphone in PDM, I want a sampling frequency of 48KHz@16bit.Typically, this requires a PDM frequency of 3.072MHz and a decimation of 64.I wonder why I need to tell CubeMX the sampling frequency, since the decimation factor is configured externally to CubeMX (in PDMTOPCM lib).To have a PDM clock  of 3.072MHz, I actually have to select a value of 192KHz for "selected audio frequency" in CubeMX, and not 48KHz.I'm a bit confused... 

hello,I am working on a design using MB1684 with STM32C011 as target. I configured UART2 as half duplex, TX only, so that I could use it for debugging, and I discovered that CubMX generates code which causes the board to hang, because it waits for both TX and RX sides to be ready. It is necessary to manually correct the generated code to have a working board.Below is the generated code and the correction:  static void MX_USART2_UART_Init(void) { /* USER CODE BEGIN USART2_Init 0 */ /* USER CODE END USART2_Init 0 */ LL_USART_InitTypeDef USART_InitStruct = {0}; LL_GPIO_InitTypeDef GPIO_InitStruct = {0}; /* Peripheral clock enable */ LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_USART2); LL_IOP_GRP1_EnableClock(LL_IOP_GRP1_PERIPH_GPIOA); /**USART2 GPIO Configuration PA2 ------> USART2_TX */ GPIO_InitStruct.Pin = DBG_UART_Pin; GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE; GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_LOW; GPIO_InitStruct.OutputType = LL_GPIO_OU

I used CubeMX 6.12 to generate code and DAC output works as intended.I cloned that project, migrated to CubeMX 6.13 and generated code. DAC output doesn't work. Migration to 6.13 also used FW H5 1.4 instead of 1.3.Comparing stm32h5xx_hal_msp.c I see the 6.13 generated code lacksRCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0}; if(hdac->Instance==DAC1) { /* USER CODE BEGIN DAC1_MspInit 0 */ /* USER CODE END DAC1_MspInit 0 */ /** Initializes the peripherals clock */ PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_DAC; if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK) { Error_Handler(); } }in HAL_DAC_MspInit(). When I add the above code to stm32h5xx_hal_msp.c in the migrated project, DAC output works as expected.No significant differences between the IOC files.Is there a problem with CubeMX 6.13?Attaching STM32H563VIT6_2.ioc (original, CubeMX 6.12, DAC works) and NGC_HW_Verification_Clone.ioc (cloned, CubeMX 6.13, DAC does

Hi,I am trying to "generate code" using an existing .ioc file. When I click on "generate code" , it is stuck. I am not able to close the window. I had to restart my laptop. I uninstalled and installed again. Tried the same process. But it didn't work. Need help. 

Hi, I'm using the last version of STM32cubeMX. When trying to generate a makefile project for the STM32L073RZ microcontroller. The resulting makefile is wrong. Build target are nonsense: ########################################################################################################################## # File automatically-generated by tool: [projectgenerator] version: [4.5.0-RC5] date: [Mon Feb 24 12:20:46 CET 2025] ########################################################################################################################## # ------------------------------------------------ # Generic Makefile (based on gcc) # # ChangeLog : # 2017-02-10 - Several enhancements + project update mode # 2015-07-22 - first version # ------------------------------------------------ ###################################### # target ###################################### ###################################### # building variables ###################################### # debug bu

If I activate the calibration output 1 of the RTC, CubeMx lags and afterwards marks the options red with "unkown conflict". GPIO does not get assigned or gets cleared if done manually before. Same behavior for 1Hz and 512Hz output. OUT2 works. restarted application and PC, still the sameuC: STM32H7R7L8H6HCubeMX V6.13.0FW versions see below Thanks and regards

I am using an stm32F103 and have configured PB4 as a output pin and this works correctly. However when the chip is reset, this pin is automatically pulled high. It appears that this behavior exists because of the pin's dual use as NJTRST. Is there a way I can reconfigure the chip so that this pin will no longer be pulled high when the NRST pin is pulled low?Thanks.

As far as I can tell from the datasheet for the STM32H753VIH, as well as the part selector in CubeMX, the device should have an OctoSPI peripheral.However, when I create a project with the device and go to the connectivity tab, I don't see the OctoSPI peripheral listed like I do in other parts.Is this an issue with CubeMX or does this part not actually have an OctoSPI peripheral in this package?The package is the 100 pin TFBGA with 0.8 mm pitch.Thanks

The only HCLK frequency possible is 40MHz (ofcourse i need higher freq)Please help me resolve this.

Good day,after troubleshooting some issues related to a bootloader, I have figured out that the address of the interrupt vector table (SCB->VTOR) is defined in a hard-coded, non linker aware way as "SCB->VTOR = FLASH_BASE | VECT_TAB_OFFSET". This means, if the FLASH region is relocated to make space for a bootloader, it requires manual changes to "VECT_TAB_OFFSET".Is there any reason, why we don't use the address of "g_pfnVectors" (the actual vector table) instead? This would always point to the vector table as defined in the startup code.Of course, I can simply add "SCB->VTOR = (uint32_t)&g_pfnVectors;" to the start of the main(), but I'm trying to understand, why the default value is hard-coded instead of using the actual table location.Can someone explain that to me? CubeMX Version: 6.12.0Controller: STM32C031K6TxAlso on STM32G431 with an older CubeMX version

 In STM32CubeMX 6.13.0 - Application Structure is Basic and gray.I solved it by editing the ioc file, it remains gray, but at least "Advanced" is selected and the code is generated accordingly.I changedProjectManager.MainLocation=SrctoProjectManager.MainLocation=Core/Src Is it intended to work like this?

Good Morning All,I have good experience on stm32 microcontrollers and cubemx, but I am new when it comes to LwIP.I followed some basic setups to generate the code using CubeMX tool.1.Selected the board as Nucleo-F207ZG,configured clock on 120Mhz.2.Enabled Ethernet module in RMII mode,configured UART3 just for debugging.3.Enabled LwIP stack and I didn't change any settings for this.I followed what by default settings were there.I have some info on LwIP so I new we need to call MX_LWIP_Process() function in while loop.I made such code that until the board gets IP address it stays in while loop and movement it gets the IP address it breaks that loop and jumps to next while loop in which only MX_LWIP_Process() function is running.Key Option Settings I am here because I am able to ping the board from my laptop,but not able to connect to the software Hercules(TCP Server).I have attached my code zip and also pasted the main.c code.

Hello everyoneI changed my PC to one with Win11 and I cannot install the CubeMX.After I downloaded and started the setup, the extracting windows appears and after the splash screen remains opened for few second and then close.Nothing else, I have a project to finish at my job and I do not have success with any of the trick in the forum.Please help me Leonardo Orazi

Hi!I have created a few projects to practice working with the STM32H series. Then, I selected SPI or I2C and used GPDMA linked-list. According to many tutorials, I should have gone to the utilities folder to configure GPDMA, but such a folder did not exist. I performed this on two PCs. CubeMX is up to date. Janusz
