Hi I'm looking for application note and design sources for STEVAL-KITXCB -Induction cooker Please share if anyone have this . Thanks

Hello Everyone,I am a beginner with STM32 (student).In TouchGFX 4.24.1 Designer, I created a simple project (two buttons and a bitmap).Then, I launch this project in STM32CubeIDE and initialize SDMMC1 and FatFS according to the AN5200 - Getting started with STM32H7 MCUs SDMMC guide. Unfortunately, I get errors, probably related to memory.When I create a project without FreeRTOS and TouchGFX, only basic handling of SDMMC1 and FatFS, everything works fine.Perhaps someone is able to help me with the correct configuration of TouchGFX + FreeRTOS + SDMMC1 on STM32H747I-DISCO or could share a working application? Thank you in advance for all the suggestions.  I have added the project as an attachment.

Hello, i need to compile example project using IAR ver. 7.40.1, (common components ver. 7.2.0), and I'm dealing with this error ".ewp was created by a newer version of the product and cannot be opened." Is there any Guide how to migrate project to older IAR version? Or set IAR compiler in CubeIDE? Thank you!

Hi,I am looking to use the STM32WL33 in a product. I am curious as to what the chip is in terms of its silicon. Is the M0+ equivalent to an available MCU?What is on the radio side? Is this an S2-LP for example?Thanks

When I change a pin configuration, the user-label I'd previously given the pin is removed and it reverts to the default.That seems to me to be a wrong behaviour ... I think it should stick be default, or should have an option to lock it.This was raised  by Arnold Bischoff back in 2016 and seemed acknowledged, but I think nothing has since happened on it.

  I just got a STM32F723 board to learn how to use USB model, and I found that when I use USB as FS host and connect a device, the register PCDET did not triger an interrupt while PENA is set, I'm wondering how can I get interrupt flag, is there any other regs to set

Hi,   I am interested in the um2647 product. Like to explore more in 6step firmware, how to download the firmware for this product. I saw that using work bench it can be extracted, but I need the complete code which cannot be done in the work bench.

Hi all. I am aware that this topic has been discussed before here:  https://community.st.com/t5/stm32-mcus-products/debugger-hangs-at-scb-enabledcache/td-p/640648 and here: https://community.st.com/t5/stm32-mcus/dma-is-not-working-on-stm32h7-devices/ta-p/49498 and I seem to have run into the same issue whilst debugging my project.The project itself is a fairly straighforward TouchGFX generated GUI on the STM32H750B discovery kit which I have imported into CubeIDE for further development.  Thus far I have added USART and SPI peripherals as the H750B must communicate with other MCUs. I'm using CubeIDE Version: 1.16.1 and the project is imported from TouchGFX Version: 4.24.1I can not be sure whether the addition of these peripherals has generated the problem or, whether the problem is inherent in the undelying architecture but either way, I am perplexed.The debugger hangs in the following function in core_cm7.h:__STATIC_FORCEINLINE void SCB_EnableDC

Hello,I am currently reviewing the S2-LP transceiver for high-bitrate/long-range communication in the 915MHz band. To achieve that, I want to interface an S2-LP with a Skyworks SE2435L front-end, as shown in the FK915V1 Evaluation board. I would like to know if it is possible to use a Balun from ST like the BALF-SPI2-03D3 to match the impedance of the transceiver with the front end. I am asking this question because in the FK915V1 schematic, the RX and TX paths are distinct, whereas using the Balun implies connecting the PAIN and TR pins of the front end together.Can this approach yield good result or am I wrong?Also, what is the recommended balun for the S2-LP, BALF-SPI2-03D3 or BALF-SPI2-01D3 ?Thank you,Robin

Hi,I use the memory management function to generate a custom ld file, but the generated ld file is wrong.

Hello All,I am getting this error while compiling the project " The float formatting support is not enabled ".I have checked use float with "printf from new lib-nano" in MCU/MPU settings save and recompile the problem didn't go!!I have added manually "-u_printf_float" in MCU/MPU GCC linker with no success.I am using the latest version of stm32cubeide 1.16.1 the MCU is stm32g031f6p6.my code in while loop: HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1, 20); voltage = (HAL_ADC_GetValue(&hadc1)/4096) * 3.3f; printf("Voltage = %0.2f\n", voltage); HAL_Delay(1000); 

Hallo to everybody.Still working on SPI&Display  adapting a code for M4 (see Different data after the 1st transfer using SPI via DMA ).I need to write only one byte at a time due to control pins of display.Starting from a NUCLEO-H563ZI and LL example "SPI_OneBoard_HalfDuplex_IT_Init" (it work!) I'trying to do it without interrupt. So, the code is like this:Spoiler (Highlight to read) LL_SPI_SetFIFOThreshold(SPI1, LL_SPI_FIFO_TH_01DATA);LL_SPI_SetFIFOThreshold(SPI2, LL_SPI_FIFO_TH_01DATA);LL_SPI_Enable(SPI1);LL_SPI_Enable(SPI2);while(!LL_SPI_IsActiveFlag_TXP(SPI1))    {}LL_SPI_TransmitData8 (SPI1, 0x55);LL_SPI_StartMasterTransfer(SPI1);//(wait for RXP flag)val = LL_SPI_ReceiveData8(SPI2);  //or belowwhile (!LL_SPI_IsActiveFlag_TXC(SPI1))    {}val = LL_SPI_ReceiveData8(SPI2); //other place! LL_SPI_SetFIFOThreshold(SPI1, LL_SPI_FIFO_TH_01DATA);LL_SPI_SetFIFOThreshold(SPI2, LL_SPI_FIFO_TH_01DATA);LL_SPI_Enable(SPI1);LL_SPI_Enable(SPI2);

  I am facing an issue connecting the STM32F4 NUCLEO-F429ZI board to an HMI screen that uses RS232 and RS485 communication standards. The HMI can communicate successfully with my computer, but the STM32 board cannot communicate with the computer except through UART3 and using a direct cable connection. This prevents me from establishing communication between the STM32 board and the HMI screen. Could you please help me identify what might be causing this issue and how I can resolve it? Thank you!

Hello,I am interested in implementing a static version of the NanoEdge AI Anomaly Detection for the ISM330ISNTR. That means I would like to us the trained knowledge from NanoEdge AI Studio for the library and not have to run a learning cycle after each power up, because my application requires many short uses, where a learning sequence each time would be very hindering. Is this at all possible?Many thanks in advance :)

Hi,is it generally possible to program/read/erase an external connected Flash-Memory (e.g. Quad-SPI-Flash) with STM32CubeProgrammer via USART bootloader? I'm using the STM32L496-DISCO board for test.External loader MX25R6435F_STM32L496-DISCO selectedBOOT0 connected to VddCOM1-RX/TX/GND (3.3 V level) connected to MCU USART3 bootloader pins PC10/PC11/GND With upper configuration MCU-Flash program/read/erase is possible, but no access to Quad-SPI-Flash (address = 0x90000000), see picture. With selected ST-LINK probe access to Quad-SPI-Flash is possible. Thanks in advance,Karsten 

I'm using the L6981C33DR bug converter to convert 24V (from an SDR-120-24 power supply) down to 3.3V. However, I've had instances where the regulator overheats and "exploaded".The circuit only needs to supply around 100mA at startup, so the current draw isn't excessive. My suspicion is that there might be a voltage spike at startup that occasionally damages the regulator, but it happens infrequently and I haven't been able to capture it on an oscilloscope.Has anyone encountered a similar issue or have any insights on how to troubleshoot this?I've attached a picture of the schematic and PCB layout for reference. Any guidance or suggestions are greatly appreciated, and I'm happy to provide additional information if needed. Chris Salimans

hello,  Currently I use nfc5 demo to read T2T card, but the read often fails,The code is as follows.When NFC-A is detected, the type is 0, and the card is considered to be T2T static void demoT2t(void){  ReturnCode err;  uint16_t rcvLen;  uint8_t blockNum = 0;  uint8_t rxBuf[16];  err = rfalT2TPollerRead(0, rxBuf, sizeof(rxBuf), &rcvLen);  printf("err %d\r\n", err);  platformLog(" Read Block %d: %s %s\r\n", 0, (err != ERR_NONE) ? "FAIL" : "OK Data:", (err != ERR_NONE) ? "" : hex2Str(rxBuf, rcvLen));} These cards are detected in the code as T2T type, and there is no encryption, and I can see from the app read that the keys are all 0xFF，I wonder what went wrong, thanks   

Hi all,Version: 1.15.1MCU : g473Before investigate deeply on my own I wonder whether if anyone have faced the same problem with Interrupt table in general ...I placed a breakpoint there :void SysTick_Handler(void){/* USER CODE BEGIN SysTick_IRQn 0 */ /* USER CODE END SysTick_IRQn 0 */HAL_IncTick();/* USER CODE BEGIN SysTick_IRQn 1 */ /* USER CODE END SysTick_IRQn 1 */}and surprisingly the code is never executed !Best regards,    

I need UART to use printf, but it's showing as disabled. How can I enable it, and I also need an example code for printf.    

I checked the datasheet and there is a memory map of 521Kbyte.But I use the stm32h523VCT6 chip.This chip has 256Kbyte of memory.Can't a chip with 256Kbyte of memory use bankswap?If it can, can you tell me the memory address? 

 Bonjour à tous, quelqu'un pourrait m'aider à trouver la référence de cette diode ou un équivalent, car je ne trouve pas la fiche technique sur internet, je vous remercie d'avance pour vos réponses 

Hi: I'm a "newbie" to STM processors. I have a board with the STM32H745BIT3 processor on it. I'd like to get the board to initially communicate via FDCAN to my laptop. My laptop has a PEAK FDCAN device on it. Is there a base CubeIDE project or .ioc file out there that I could use to initially get a prototype project running to communicate with the laptop. Once I get initial communication working, I plan on trying to use the emotas CANOpen stack. Any comments regarding FDCAN communication on a H745 processor is much appreciated.

im trying to create a project that write something in the serial monitor(raed/write) . i followed many tutorials step by step but i everytime my serial monitor doesnt print my message( i used tera term/putty/and even the serial monitor in the ide "command shell console". - i already fixed the baud rate to 115200- i already confugured the usart3 pins pd8 and pb11 or pd8 and pd9 for RX and TX-i already activated the NVIC settings in usart3 menu- this is the code that i used in while(1) part : while (1){/* Transmit "Hello, World!" over USART3 */char msg[] = "Hello, World!\r\n";HAL_UART_Transmit(&huart3, (uint8_t*)msg, sizeof(msg) - 1, HAL_MAX_DELAY); /* Add a delay to avoid flooding the serial monitor */HAL_Delay(1000);}  the code was built with 0 errors 0 warningsis there something that i misssed or i need to ckeck or did wrong im using stm32f407G disc1 board and it's only connected to the c through the cable
