STM32 MCUs Software development tools

I have managed to get LwIP working and my Nucleo can be pinged and discovered via IP scanner tool. I want to get TCP/IP server working and I saw there are some files called TCP inside LwIP Library I just can get my head around it. But I have used TCPServerRAW that I got from a tutorial. Everything is fine until server need to transmit back, well until program wants to write into (probably unwritable) memory location. I just can't figure out where I can change those parameters so that TX pbuff dosen't end up in HardFault. I tried to setup MPU but I can't find locations soooo...I am using latest CubeIDE update (1.11.0).Below are the files I am using.

Hello, the question was already posted by another user ("how to access public variables in a base class"), but never answered.In other words, the CubeMonitor shows only variables contained in derived class, all inherited variables are invisible. Is there a way to get around or fix this?

I installed CubeMX but i can't see the program when i try to search it on windows. Other ST programs can't see it too (Motor Control Workbench)

There is an error in the ADC LL example projects on STM32G0 (Fw 1.5.1).Initalisation function (MX_ADC1_Init) call function LL_ADC_SetTriggerFrequencyMode()with inadmissible argument LL_ADC_CLOCK_FREQ_MODE_HIGHpermissible arguments are LL_ADC_TRIGGER_FREQ_HIGH or LL_ADC_TRIGGER_FREQ_LOWAlso CubeMX generate the same problem.

Strange problem again.I created a new empty STM32 project and selected C++. Now I made two functionsvoid test(uint8_t a) {   }   void test(uint16_t a) {   }But I get an error of redefining the function test. The file (like all source files) has the ending .c and if I change it to .cpp then it works. But if I change any of my other source files to .cpp the functions in those files are not found any more. If I leave the ending .c then I cannot overload functions. What is going on here???

Hi,I have run into a problem I can't find a solution for. Basically, I want to have in the ELF file which is generated during the build process the relative paths to the source files. Currently absolute paths are put into it to the source files, so I can’t use it without adapting them on another computer.I need it because I am using a J-Link debugger and want to create a Configuration file for Ozone which runs independent from the computer importing just the elf file. Does anyome have an idea how I could adapt the Comoiler/Linker Configuration to use relative paths?Thank you and Greetings!

Hello,maybe this might be of interest to many people using CubeIDE and HAL libraries.I've seen many threads here complaining that after a CubeIDE update HAL-related sources didn't work anymore.That didn't happen to me, mostly because I don't use many HAL sources.But just in case, how can I prevent that a CubeIDE update also updates the HAL files in my project?I usually start with CubeMX, then generate code for CubeIDE, with separate .h/.c files per peripheral, then I try not to use CubeMX again.If necessary I start another CubeMX project so that nothing of my original project is overwritten by CubeMX.

Hi!Problem described in title. The same setup working fine with 6.5.0 version of STM32CubeMX.Screenshot attached.

Hello,After creating a blinky project in CubeIDE version 1.11.0 running on Linux and setting up FreeRTOS within the .ioc file, the default task fails to run.A project created with STM32CubeMX V6.6.1 works, but when it was migrated to V6.7.0 (by opening the .ioc file and re-generating the code), it no longer works.It was found that: The osThreadNew(Task, NULL, &Task_attributes); functions were never generated in main.c! In its place, a copyright notice was printed instead (what is printed at the top of main.c).I assume someone used the wrong variable in the code generation software?Apologies if this is not the correct place to post these bugs, if not, please direct me where this information should be sent.

Hello,In my project I need CPU frequency independent CANBUS and SAI2 Master clock output.CANBUS is running out of PLL2P clock, while SAI2 MCLK is selected from PLL3PIf I only enable one or the other, they work great, but if I enable them all together desister !  My CANBUS traffic is just garbage and it hangs while the SAI2 clock is good. They are all on completely different PLL’s I don’t understand how it happens  and how to fix itHere is SAI2_MCLK enable:void DCMI_Master_Clock_Config(void) { LL_AHB2_GRP1_EnableClock(LL_AHB2_GRP1_PERIPH_GPIOC); LL_RCC_SetSAIClockSource(LL_RCC_SAI2_CLKSOURCE_PLL3); LL_APB2_GRP1_EnableClock(LL_APB2_GRP1_PERIPH_SAI2);   LL_GPIO_SetPinMode(GPIOC,LL_GPIO_PIN_11,LL_GPIO_MODE_ALTERNATE); LL_GPIO_SetPinSpeed(GPIOC,LL_GPIO_PIN_11,LL_GPIO_SPEED_FREQ_VERY_HIGH); LL_GPIO_SetAFPin_8_15(GPIOC,LL_GPIO_PIN_11,LL_GPIO_AF_13); LL_GPIO_SetPinOutputType(GPIOC,LL_GPIO_PIN_11,LL_GPIO_OUTPUT_PUSHPULL);   SAI2_Block_B->CR1 &=~SAI_xCR1_SAIEN;

I'm setting up the DMA to move received bytes from USART3 to a circular buffer. But the DMA don't move the received data to the buffer. The received data is received by USART3 (The DR contains the received byte and SR.RXNE is set to 1).All I need to do to make it work is to edit in main.c. I move the call to MX_DMA_Init() to be called before MX_USART3_UART_Init().Is this a STM32CubeMX bug?/* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); // I moved MX_DMA_Init() up here. Then it works. MX_USART3_UART_Init(); MX_TIM1_Init(); //MX_DMA_Init(); // DMA don't work if we call MX_DMA_Init() here MX_DAC_Init(); MX_TIM14_Init(); MX_ADC1_Init(); MX_SPI3_Init(); MX_CRC_Init(); MX_I2C1_Init(); /* USER CODE BEGIN 2 */

Hi,I have installed STM32CubeMX v6.7 on my laptop. The installation was successful.Loaded a project which was setup with STM32CubeMX v6.3 using FW_GO v1.5.0.The code is generated successfully, however when pressing to open the project, " Not a valid ioc file" errors on the screen.Attached STM32CubeMX log file.Any idea how to resolve it ?

Hi all,Trying to setup SPI for ssd1306 in STM32CubeIDE based on the code from "afiskon" in Github.Problem is that I'm new to this processor and the IDE.Could someone please help me?I'm using the NUCLEO-F302R8 board and I have set up the following GPIO ports additional to the SPI3 bus.Does anyone have a good example, because I can't find an howto on Youtube or somewhere else.BRJohan

I have wrote an product with tcp communication, last modification September 2021...Today I need a small evolution ( move from HSI-RC to HSE)...the Ethernet does not run now.I have try to work with doc concerning the new driver versus legacy...help-me.Eric

Just try it:std::tuple<int, int, int> testTuples() { return { 1, 2, 3 }; };   struct Test { int a = 0, b = 0, c = 0; };   int main() { auto [a, b, c] = testTuples(); void* mem = malloc(3 * sizeof(int)); auto test = new(mem)Test; }The code above compiles in Visual Studio, does not compile in STM32CubeIDE.Surprisingly "std::pair" works.Though tuples are just some syntax sugar, no "placement new" is really annoying, because you either must manually re-initialize structs when needed, or allocate new memory, or use ugly deprecated hack with "memset()".

Installation and usage of STM32CubeL4

I am encountering breaking graphical problems with the configuration perspective and want to try a clean uninstall/reinstall to try to resolve it.What is the preferred method for uninstalling STM32CubeIDE on Linux?

and build analyzer is showing those memory regions. I did not have this problem before. The new project name is AC_2 which is changed from AC_1. Now under build analyzer I see AC_1.elf/AC_2/Debug -27th August -2022, 6:33:40 PM. When I expand the projects tab and under Debug I see only AC_1.elf -[arm/le] though in the folder I see AC_2.elf. It is important for me to know the memory usage for my current project. Can someone help me please? This is a bit urgent and request your help ASAP. Appreciate your time and help. Thank you.

 I am using Linux Linux kubuntu 22.10 5.19.0-26-generic and when I click on the GPIO Pull-up/Pull-down column elements nothing happens except the color of the row changes.

STM32Cube IDE w/ STM32L562QEIX part - generated a .IOC to match my hardware. Have a Sky High eMMC 8-bit part configured to use the eMMC/SD peripheral in 8-bit mode. Also using FS USB CDC as another large peripheral. I can program/debug the chip with my Segger probe up until I power down the probe and UUT for the the night. Once that happens I can no longer connect J-TAG, I get an unable to power up DAP error. I have the J-TAQG fully configured to use the full 5 pins as it performs better than SWD for debugging. I set the HAL Settings "Set all free pins as analog (to optimize power consumption). Is there a bug or quirk here? Does this disable my J-TAG? If not what did? And why only after a power cycle? I've bricked two chips and am on a third. It's consistent. I want J-TAG enabled while I am developing.

Hello,I know that the static stack usage is available in the stm32cubeide, but I'm wondering can I do it use a command line?after more googling, I found that there is command for arm "armlink " that can run to get the stack used for each obj file ARM Compiler User Guide Version 6.6but i couldn't find this command in stm32cubeide, , so what is the corresponding command in ST compiler?Thanks,Mohammed

Hello,Recently I got a STM32H745I-Disco evaluation board. In this board, the user button (bluebutton) is physically connected to PC13 pin and is the TAMPER 1.I was able to get the TAMPER 1 interrupt working in the M7 core but not able to get theinterrupt in M4 core. I want to get TAMPER iterrupt on M4 becouse i set M7 to sleep.I configured the RTC tamper 1 interrupt as following. (As i did in M7, I only change the initilizer to Cortex-M4)  This is the same configuration that I use in M7 core and works perfectly. The code that is autogenerated is the same in the M4 core than in the M7 core.I add the following code as I did in M7 core.But, the program never enters in the function because the TAMPER_1 is not working in M4 core.Can someone explain if i need to configure tamper different to be used in M4 corethan M7 core? Is possible to get TAMPER interrupt in M4 core?Thank you very much.

to see my data on python what library or code should I use in STM32(CubeIDE) ? Could you share with me example!
