HiI have a question about the current limitation embedded in the RHFL4913, as there is an inconsistency between two information in the last datasheet (Rev22).in the Table 5 (§4), we can find the “Iolim” (overcurrent protection limitation) range defined as 0.8A minimum and 2A maximum. In the §5 (Figures 42 and 43) we can see that the minimum recommended value for “Ish” is about 0.75A. If we divide this value by 1.6 to get the corresponding “Iolim” value, we obtain 0.47A. This is not consistent with the 0.8A value found in the table 5.Can anybody help me with this problem ? Maybe the Figures 42 and 43 are considering “Iolim” instead of “Ishadj” ? Or there is a mistake in the Table 5 ?Thanks for your helpregardsPhilippe PELEGRI

Updated to the latest version and found that VSCode starts very slowly. It was discovered that the problem lies with the STM32Cube.I have exported the startup time of VSCode.The time taken by STMicroelectronics.stm32cube-ide-build-cmake is 335054ms，~6minSTMicroelectronics.stm32cube-ide-core is 23993ms 

Hello,We are using two ST67W611M1U modules (no on-module antenna; external 2 dBi dipole on MHF4) with an STM32H563ZG host, bare-metal, SPI host interface at 10 MHz (the same behaviour was reproduced at 20 and 40 MHz). AT firmware reports AT version:1.0.0.1 (Sep 4 2025 11:32:47), macsw 1.6.44; we are working from the Web AT Documentation v2.0.106.Topology: one module runs as SoftAP (AT+CWMODE=2, AT+CWSAP="…","…",1,3,4,0, AT+CIPMUX=1, AT+CIPSERVERMAXCONN=3, AT+CIPSERVER=1,5000,"TCP", AT+CIPRECVMODE=1), with two stations attached: a second ST67 module and a Windows PC. Steady-state traffic is about 36 kB/s outbound from the AP to the PC (AT+CIPSEND=<link>,1024, ~40 per second) plus about 10 kB/s inbound from the second module (passive receive, one AT+CIPRECVDATA of ~1 kB per 100 ms).We have collected several hundred boot/join cycles with full host-side logs and would appreciate answers or pointers on the following points.1. Static station IP is never applied to the interface. On the

Hi, I got this PN from the customer, but I didn’t find much information about this PN. I would like to know if the datasheet and 2D/3D is available? 

HiI’m looking for the maximum sink current capability on the OCM pin of the RHFL4913, and I find some inconsistency between two information available in the last datasheet (rev 22 dated of july 2025).At the end of the table 5 (§4) I get a 0.38V voltage value for a 24mA sinked current in the pin. But in the §7.5 I find a 10mA sink current value.Which one can I consider as the maximum sink current value ?Thanks for your help.Regard

Hello,I would like to know when you plan to align your gnu-tools-for-stm32 with Arm GNU Toolchain (15.3.rel1)?Your toolchain is quite old.Or is there a way to use Arm GNU Toolchain (15.3.rel1) instead?It blocks me from moving from CLion (Arm GNU Toolchain 15.3) to STM32CubeIDE for Visual Studio Code. Best regards,Endriu

Hi, I want to design a 600 W converter which should work during power shut down 190 V to 60 V input and output voltage will be 300 V. Switching frequency 150 kHz to 190 kHz. Want to use L6462A IC as there is a evel board which perform the same (ACDC  -- PN: EVL6462A-250W-M). Operation time = 100 msec.I also need an enable signal to turn on the DCDC converter.Please let me help to design the schematic and are we able to use L6462A IC for the application. Additional Information:Topology is already selected and simulation is done. --- Non isolated boost converter. L6462A is ok to use? ST already build an eval board as PFC. Can anyone provide me the schematics or suggestion for the DCDC converter. Peak current controller is fine. I also want to mention that we already build the dcdc converter with TI28379D microcontroller. Reason to use the IC (L6462A or else) because we want to bypass the software coding.

Hello,I am working on CAN-FD project and and I am able transmit and receive data. Currently it is continuously sending and receiving the data. But I want to send data only when receiver sends data requests. How can I do that? thanks for help

Hi, Am interfacing STM32H743 FDCAN classic with STM32F7 CAN. When I tried transmitting data from F7 to H7, within a minute H7 stop receiving data. I also tried debug the problem on F7 side and found that breakpoint hit on following condition inside the HAL_CAN_AddTxMessage() function in stm CAN driver: else  {   /* Update error code */   hcan->ErrorCode |= HAL_CAN_ERROR_PARAM;   return HAL_ERROR;  } }It means, all three mailboxes are filled that's why this condition getting true. I tried example from STM32H7 repository but same results.on the other hand, when H7 is configured as FDCAN only, in this case F7 is transmitting without any issue. Please help, am stuck with this problem from last 5-7 days. thanks in advance.

Hi,I'm struggling to get the CAN working on a project I'm working on with the STM32F446ZET6. With the project below (CastletRestart) i just get a flat line of 3.3V high on the TX line for CAN1, this is being tested in loop back mode, with the TUT_CAN_F446 project the can works (downloaded from a tutorial) in loopback mode, as far as i can see ive replicated everything across but it still isnt working.Its likely to be something silly and i do apologise for this being the case but i cannot see what ive missed having reviewed the code countless times.P.s. i am aware the Tutorial project is targeted at a different micro, but the CAN1 ports are the same.Any advice welcomed, thank you for your timeChris

According to the reference manual, enabling USB requires APB2 to operate at a minimum clock of 12MHz. Cubemx2, however, does not validate this constraint and will proceed even if an invalid clock is configured

Hello,I am attempting to communicate between my STM32H7B3I-EVAL and a Vector CANalyzer (VN1630A). I previously reached out to figure out why my CAN messages from the CANalyzer are not being received by the STM32 MCU. There was a belief that it was the filters causing the issue, so I did not initialize the filters and tried to see if any message was being received. There are still no messages being received, but I can send them from the STM32 to the CANalyzer without issue. I would like to find out why my code is not working, but I have some specific questions to try and assist my thought process:If the FDCAN_FilterTypeDef is a defined variable but not initialized, it will not filter, correct?Is the function correct for receiving data from the RXBUFFER?if(HAL_FDCAN_GetRxMessage(&hfdcan1, FDCAN_RX_BUFFER0, &RxHeader, RxData) != HAL_OK){ Error_Handler(); }Setup Picture: #include "main.h"   /** @addtogroup STM32H7xx_HAL_Examples * @{ */   /** @addtogroup T

I am tried to send a simple message over CAN, but I got the broken Frame when transmitting, I capture it on a Logic Analyzer(Pic Below), it seems that it is Transmitting but not Correctly.Did I did somting wrong or Did I miss Someting?And here is my Code:int main(void) { /* USER CODE BEGIN 1 */     /* USER CODE END 1 */   /* MCU Configuration--------------------------------------------------------*/   /* Reset of all peripherals, Initializes the Flash interface and the Systick. */   LL_APB2_GRP1_EnableClock(LL_APB2_GRP1_PERIPH_AFIO); LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_PWR);   NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_4);   /* System interrupt init*/ /* SysTick_IRQn interrupt configuration */ NVIC_SetPriority(SysTick_IRQn, NVIC_EncodePriority(NVIC_GetPriorityGrouping(),15, 0));   /** DISABLE: JTAG-DP Disabled and SW-DP Disabled */ LL_GPIO_AF_DisableRemap_SWJ();   /* USER CODE BEGIN Init */   /* USER CODE END In

This is a weird one :) I'm using the STM32F769 device, and I have the LTDC peripheral running at low speed (8MHz PCLK). When I send a CAN message to the unit, the CAN RX interrupt is invoked, and only when the ISR exits,  an LTDC error interrupt is raised, which indicates FIFO underrun. Here is a code snippet below:void conv_u32_to_buf(uint32_t num, uint8_t buf[]){   memcpy(buf, (void*)&num, 4);}void CAN1_RX0_IRQHandler(void){   CAN_TypeDef* can = CAN1;   // If CAN message available in the FIFO   if ((can->RF0R & CAN_RF0R_FMP0) != 0U)   {      uint8_t data[8];      // Get pointer to mailbox      CAN_FIFOMailBox_TypeDef* mailbox = &can->sFIFOMailBox[CAN_FILTER_FIFO0];        // This does not work      uint32_t tmp = mailbox->RDLR;      conv_u32_to_buf(tmp, &data[0]);      tmp = mailbox->RDHR;

I would be interested in implementing a FDCAN communication between two STM32H747 MCU boards. I have implemented communication on a single board in External LoopBack mode. However, I am having problems understanding how to connect the two boards. Do any of you know how to do this, or do you know a good guide?
