STM32CubeMX (MCUs)

Hi,currently, I am trying to debug an empty project created with STM32CubeMX (ver. 4.26.1 and 4.27 tested) in combination with SW4STM32 IDE (ver. 2.5 and 2.6) tested.But before the empty while(1) loop in main.c is reached the output of the debugger console is the following (see the attached screenshot):Program received signal SIGINT, Interrupt. 0x080016ce in main () at ../Src/main.c:98 98 MX_USART2_UART_Init();I have several Nucleo-F303RE boards tested on different computers with Windows 7 and 10 and use the HAL libraries ver. 1.10 (and 1.09 tested).Since I have debugged a project in the same way successfully a few weeks ago, I think the error should not be very complex.Can anybody please help me to understand the reason for the SIGINT interrupt?Thanks in advance

Hello, I've brought a new stm3220xG eval board for some development purpose. while going through examples code of STM32CubeMX all of them working fine individually but when I'm trying to use some parameter/functions and files into another code those newly added functions and files isn't working at all. In my project I've added "USART3 printf" example's files and all other initialization related functions into "LWIP TCP/IP ECHO SERVER" as I need a debug port. so does anyone has any idea or knowledge about what possibly could goes wrong? either I'm missing something or improper initialization.?Thanking with regardsAatif shaikh

Hi,In STM32CUBEMX software version 4.27.0 , when I generate code for keil, it changes compiler setting from my own -O0 parameter to -O3. If I change back this parameter in keil, in next code generation of stm32cubemx it changes this parameter again. It is very annoying. V4.26.0 is OK.Thanks,

I try to configure this module from STM32CubeMX, but I can not find how can I do it. It is not clear how can I starting a design with this module...

STM32CubeMX and the L4 HAL 1.13.0 now sport an option to change the number of supported USB configurations.I am trying to implement a USB interface that allows the host to choose between a CDC configuration that draws 500mA and one that draws 100mA. I have a battery powered device, and I want to present a CDC interface whether or not the battery can be charged.It seemed like USBD_MAX_NUM_CONFIGURATION would help here. It seems to be a step in the right direction. I see two identical configurations enumerated. But I don't see any code in the USB layer that does anything with the configuration number when the host is enumerating or which would allow an application to alter or set a specific configuration.Is there any documentation or example code illustrating how to make use of this new feature?

For more details check the screenshot.Thanks!

Hi. I have created app with SDMMC+FreeRTOS+FatFS for STM32H743 Eval board using CubeMX 4.26.1 and STM32CubeH7 Firmware Package V1.3.0 . And found some weird thing: every time when f_write function called also called funcction HAL_SD_ErrorCallback with error code SDMMC_ERROR_CMD_RSP_TIMEOUT. This happened when HAL SD driver send STOP TRANSMISSION command after WRITE SINGLE BLOCK complete. In code this is line 1460 in stm32h7xx_hal_sd.c file:/* Stop Transfer for Write Single/Multi blocks or Read Multi blocks */ if((context & SD_CONTEXT_READ_SINGLE_BLOCK) == 0U) { errorstate = SDMMC_CmdStopTransfer(hsd->Instance); if(errorstate != HAL_SD_ERROR_NONE) { hsd->ErrorCode |= errorstate; HAL_SD_ErrorCallback(hsd); } }SD card continue work fine, but spend time for handling this command.Maybe don't need send STOP TRANSMISSION command (CMD12) after WRITE SINGLE BLOCK command (CMD24)?

I generated a project using the LL libraries for the STM32L011 as the HAL is far too bloated to use with this part. After porting some known working DMA TX code from an old F103 StdPeriph project, I couldn't get anything to transmit out. What I found was missing was that the initialization function never sets the peripheral address to be the UART's TDR. Calling the following line solves the problem and I believe it should be done in the intialization instead of during the TX function where I have it now from debugging:LL_DMA_SetPeriphAddress(DMA1, LL_DMA_CHANNEL_2, (uint32_t)&LPUART1->TDR);My DMA TX function for reference:void LPUART_DMA_TX(uint8_t* data, uint8_t size){ LL_LPUART_DisableDMAReq_TX(LPUART1); // Disable DMA requests from LPUART LL_DMA_DisableChannel(DMA1, LL_DMA_CHANNEL_2); // Disable DMA channel LL_DMA_SetPeriphAddress(DMA1, LL_DMA_CHANNEL_2, (uint32_t)&LPUART1->TDR); while (DMA1_Channel2->CCR & 0x01) // While EN bit is high __NOP(); // Wait for dis

Hello,I'm independent developer involved in a STM32H7 project.I need to activate traces in SWV console of TrueSTUDIO. I've attached my .io CubeMX project, I think it is well configured.I've configured in the debugger tab of TrueStudio : SWD // SWV checkbox I've checked the port 0 of "ITM Stimulus ports" zone in the "Configure Trace" window and activated "Start Trace" button. Finally in the main loop of my program i've added : ITM_SendChar('T');Nothing appear in the SWC console, is anybody can help ?

Hello, I can`t figure out how to achieve the following with STM32Cube HAL.I need to setup a timer, that counts to a specific value and generate an Interrupt. After this, the timer needs to keep counting up, until it overflows. This Overflow should alos generate an Interrupt. I can`t figure out, how to do this. I also tried PWM -no output but it is not working. I don`t want to set a GPIO, I only need a Timer that acts like a PWM. Count to a value -> Interrupt, keep counting till overflow-Interrupt.Thanks

I develop an app with ETH interface and static IP address based on the STM32F207 MCU. The IP address shall be derived from status of input pins, like DIP switch. CubeMX allows to set the static IP address however does not accept user constants. This IP address is then set to LwIP internal variables in the lwip.c MX_LWIP_Init() routine. I would need to change the IP address in the routine before the LwIP stack gets initialized. I would expect some /* USER CODE BEGIN x */ section there, like in the ethernetif.c low_level_init() routine for easy changing the MAC address (section /* USER CODE BEGIN MACADDRESS */). Any ideas how to do it without my code being overwritten each time CubeMX re-generates the code? Maybe I miss something. I tried a few hacks (like #undef the #define ip_init()) without success. Would be nice to be able to define own USER CODE section. CubeMX version: 4.27.0

Hi, colleges! I use Nucleo-144 STm32F767 development board to learn USB.Now - Application example - device USB MSC.How can I write/read to/from MCU from the PC?Do I need some software on PC? Or can I do it by file manager (f.e. Total Commander)? Please, reveal me the process? Or where can I read about it?

​whenever i open cube mx, this error message make me be nervoushow i can solve this problem please help me

Below images show a PCC step configuration window and my clock tree configuration. As seen i can not change info under clock tab of PCC. Anybody know the reason ?

I use STM32Cube Ver 4.26.1 to generate LWIP code with HTTPD, it keep print "Assertion "HTTP headers not included in file system" failed at line 2271 in ..\Middlewares\Third_Party\LwIP\src\apps\httpd\httpd.c " .I find it is in file "httpd_opts.h", " LWIP_HTTPD_DYNAMIC_HEADERS" is not defined.From Cube ==>Configuration ==>LWIP ==> HTTPD, nowhere can I define " LWIP_HTTPD_DYNAMIC_HEADERS".Any suggestions?

How can I set CPU and MPU parameter in CORTEX_M7 for ethernet communication?

I ran into problems with the LAN8742A on the STM32F746-G discovery board. CubeMX is generating wrong values for some registers resulting in a misconfiguration of the MAC. I noticed this becuase about a quarter of all packets send were lost and a lot of duplicate acknowledgements were send in the TCP connection.After some research I found this thread: https://www.olimex.com/forum/index.php?topic=2495.0I can approve these changes. By correcting the values, the board works like a charme. I have CubeMX 4.26.1 installed and generated the files about 3 weeks ago. Will this be fixed to help other developers? These were some exhausive last days finding this bug.I also want to maybe help others to find a soulution for the described symptoms.Finn

I want to implement a callback for USB connection / disconnection.I see that CubeMX generates HAL_PCD_ConnectCallback, as __weak in file stm32f7xx_hal_pcd.c, but the problem is that it's already defined in file usbd_conf.c. And there's no option for user code there. So how can I add my code to this callback?Thanks

Hi, colleges!I use Nucleo-144 STm32F767 development board to learn USB. Now - Application example - device USB MSC. The example uses SD card, with I haven't. I want to use internal instead of SD card. So, I changed the "usbd_storage.c" file. Plugged and not played =) Error - Cann't start this device (code 10). My STM32 is falling in HardFault_Handler. I've put break point in "Handle Enumeration done Interrupt" and seen the process has stopped. The enumeration process is done. Ok. What is going then? Which step is next? Where I need to put my break point? I don't really know how to debug USB transaction and communication process. Wireshark doesn't see my device at all. /* Private variables ---------------------------------------------------------*/ uint8_t usbMassStorage[0x1000]; ....   int8_t STORAGE_GetCapacity(uint8_t lun, uint32_t *block_num, uint16_t *block_size) { *block_num = sizeof(usbMassStorage)/512; *block_size = 512; return 0; }   int8_t STORAGE_IsReady(uint8_t

Hello,I am currently working on a project for which I need to transmit data from my STM32 Nucleo 144 to micro SD via SPI. I ordered this breakout board to use:https://www.waveshare.com/micro-sd-storage-board.htmThe board came with a driver, however it is for the STM32F10 series, and as far as I can tell is not easily ported to the STM32F7 series. I found that in the STM32Cube_FW_F7 there is a driver called adafruit_shield_sd.c, which I have tried to implement into my project and it appears to work, however when I try to initialize my sd card I receive an error (BSP_SD_Init returns 0x01, or BSP_SD_ERROR). I cannot tell if this is because I have wired my breakout board incorrectly or because the adafruit driver is incompatible with my breakout board.If I was confident that I was wiring my board up correctly, troubleshooting this might be going a little smoother but this is my first crack at adding a peripheral to my board.In CubeMX, I have SPI1 enabled, using:PA5 = SPI1_SCLKPA6 = SPI1_MI

I am working on a project that integrates the cubemx-classb library, which depends on V1.5.0, and also want to use STM32CubeMX for other configuration. However, it appears that the STM32CubeF0 Firmware Package V1.5.0 configured by the STM32CubeMX tool provides outdated (v1.3.1) HAL header files. Generated initialization files are not compatible, specifically WWDG references non-existent MACROS that don't appear until V1.5.0.

Let's take example STM32F407 MCU TIM3_CH1 timer is configured for indirect capture mode meaning this channel is triggered by TIM3_CH2 input signal. In this mode TIM3_CH1 external pin is not used. Can it be configured as this channel' output? If yes, then how to do this? STM32CubeMX peripheral configurator only allows one choice for any channel such as "Input Capture Indirect Mode", choosing it does not leave option to choose channel 1 pin as output. Or could this pin configuration be done manually in software initialization in addition to the Indirect Mode? My goal is to use this pin for testing the TRGO Master clock output generated in this timer and internally connected to another timer input. Please advice.

Hi, I have some trouble to handle ADS7953 with HAL_SPI_TransmitReceive_DMA api,if using HAL_SPI_TransmitReceive api, it takes long time and impact other operations,so I hope to reduce the communication time with HAL_SPI_TransmitReceive_DMA in the communication of SPI, please help to let me know the method if possible, with detailed example, I update my code, please help to review it, if finding something, please help to let me know what I should modify and how to modify with detailed example or explanation,Thankful for your kindness in advance,thanks.My code is, CS_Low;    if(HAL_SPI_TransmitReceive_DMA(&hspi2, cmd, data, 2) != HAL_OK) { /* Transfer error in transmission process */    } uint8_t state = HAL_SPI_GetState(&hspi2); while (state != HAL_SPI_STATE_READY) { state = HAL_SPI_GetState(&hspi2); Hal_DebugPrint("SPI2_HS1_ManulMode hspi2 State is: %d\r\n", state); }CS_High;and the setting case of SPI & DMA is, /* USER CODE

Hi, I have a problem with a minimal project using STM32CubeMX (version 4.27), an STM32F407VG and generating code for MDK-ARM5 (Keil). I create a new project, configure UART3 on pins PD8 and PD9. I add a simple printout on the UART in the main loop (not in an interrupt) giving the HAL_GetTick() as an ascii string and the value stays at zero continously. Similarly, any calls to HAL_Delay etc. hangs the processor. I've also tested to configure the RCC (HSE crystal) and clock settings (HSE 8mhz, using "resolve clock issues") in addition to the UART, but with the same results. Am I missing some other important configuration to be done in the CubeMX gui or should I add any user code to ensure that SysTick_Handler is called?The only added code are as below, in the sections indicated by the USER CODE comments in Src/main.c. /* USER CODE BEGIN 0 */ void uart_send (const char *str) { uint16_t size; for (size=0; str[size] != 0; size++); HAL_UART_Transmit(&huart3, (uint8_t *) str, size, HA
