Hello Everyone,I have a two arduino boards communicating with each other on a CAN Bus. Arduino is connected to CAN Bus via MCP2515 .Both arduino are communicating correctly with each other. Here is an example of my transmitter on arduino:/*************************************************/#include <SPI.h>#include <mcp2515.h>/*******************MESSAGES DEFINITIONS*****************/#include <SPI.h>#include <mcp2515.h>struct can_frame canMsg1;struct can_frame canMsg2;MCP2515 mcp2515(10);void setup() { canMsg1.can_id = 0x0F6; canMsg1.can_dlc = 8; canMsg1.data[0] = 0x8E; canMsg1.data[1] = 0x87; canMsg1.data[2] = 0x32; canMsg1.data[3] = 0xFA; canMsg1.data[4] = 0x26; canMsg1.data[5] = 0x8E; canMsg1.data[6] = 0xBE; canMsg1.data[7] = 0x86; canMsg2.can_id = 0x036; canMsg2.can_dlc = 8; canMsg2.data[0] = 0x0E; canMsg2.data[1] = 0x00; canMsg2.data[2] = 0x00; canMsg2.data[3] = 0x08;

I have two boards, one with STM32F303 with CAN 2.0 and a new board (same electronic, only MCU is different) with STM32G474. Software is identical too, except for the CAN/FDCAN. So I had to migrate the software from CAN 2.0 to FDCAN Classic in order to communicate with the other system boards. In the treatment of the received frames, I noticed that the CAN 2.0 is faster in managing the communication than the FDCAN Classic. Can anyone confirm that ? and if so why does it take so long to the FDCAN classic ? As I send frames to both board, the STM32F303 program timing isn't affected, for the STM32G474 I measured a delay of some ms. Clocks are as follow:STM32F303 : CPU: 72 Mhz CAN baudrate: 500Kb/sSTM32G474 : CPU: 170 Mhz FDCAN classic baudrate: 500kb/s

hi there.I'm trying to CAN transmit on my target board.my board is not to send CAN message on stm32cubeide . but I confirmed that my board send CAN message on mbed.Can I how to send CAN message on stm32cubeide?? I intended CAN baudrate 500kbps, sampling point 75% and my apb1 clock is 18Mhz, HSE is 8Mhz, and my crystal is 8Mhz.below is printf() debug message when my board running and stop.Always debug message show me the message such as below..<Can Send Success: 1<Can Send Success: 2<Can Send Success: 3<Can Send Success: 4<Can Send Success: 5<Can Send Success: 6<Can Send Success: 7<Can Send Success: 8<Can Send Success: 9<Can Send Success: 10<Can Send Success: 11<Can Send Success: 12<Can Send Success: 13<Can Send Success: 14<Can Send Success: 15<Can Send Success: 16<Can Send Success: 17<Can Send Success: 18<Can Send Success: 19<Can Send Failmy source code attached .please check my error...regards..

Hi all,I have a CAN 2.0 network up and running with a F407 and some F103. I added a board with a G0B (fdcan). I couldn't get my hands on a FDCAN-tranceiver. I tried to get it working in classic mode (from repository example) with a CAN2.0 tranceiver. I cannot receive any message.So my question is:Is it even possible to configure the G0B to work with a classic CAN2.0 tranceiver?If yes, what would the FDCAN config look likeThank you in advance!Best regards,Philipp

I've been working on getting the STM32f7-EVAL operational to later on migrate it to STM32F767II. For this we decided to split up functionality into 3 sections, there is a forward facing application that has the main and specific business logic. Currently the main issue is that the CAN bus transmit (polling) is working flawlessly yet the receive (interrupt) seems to be non-functional. RF0R.FMP0 remains at 0x0, while FMPIE0 is set (1). it seems as if CAN_RF0R is disabled for some reason. Even though CAN_RX0_IRQn is enabled.  /* CAN1 interrupt Init */  HAL_NVIC_SetPriority(CAN1_RX0_IRQn, 0, 0);  HAL_NVIC_EnableIRQ(CAN1_RX0_IRQn);also the notification is enabled:HAL_CAN_ActivateNotification(&canDef, CAN_IT_RX_FIFO0_MSG_PENDING); after the NVIC and CAN are initialized.void HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeDef *hcan)is the callback that i'm using.I also verified using messages coming into the MCU by scope and logic analyser. There is an additional device attached to the CA

Hello,I'm trying to set up an interrupt when my FDCAN controller received a CAN message. MCU is an STM32G0B1I went into STCubeMX and I enabled these interrupts:This generated some new functions instm32g0xx_it.c:void TIM16_FDCAN_IT0_IRQHandler(void){ /* USER CODE BEGIN TIM16_FDCAN_IT0_IRQn 0 */  /* USER CODE END TIM16_FDCAN_IT0_IRQn 0 */ HAL_FDCAN_IRQHandler(&hfdcan1); /* USER CODE BEGIN TIM16_FDCAN_IT0_IRQn 1 */  /* USER CODE END TIM16_FDCAN_IT0_IRQn 1 */} /** * @brief This function handles TIM17, FDCAN1_IT1 and FDCAN2_IT1 Interrupt. */void TIM17_FDCAN_IT1_IRQHandler(void){ /* USER CODE BEGIN TIM17_FDCAN_IT1_IRQn 0 */  /* USER CODE END TIM17_FDCAN_IT1_IRQn 0 */ HAL_FDCAN_IRQHandler(&hfdcan1); /* USER CODE BEGIN TIM17_FDCAN_IT1_IRQn 1 */  /* USER CODE END TIM17_FDCAN_IT1_IRQn 1 */}This appears to call this function for RX FIFO on 0 and 1 /* Rx FIFO 0 interrupts management ******************************************/ if (RxFifo0ITs != 0U) { /* Clear the Rx FIFO 0 flags */ __HAL_FD

I am currently developing a USB Mass Storage application using the STM32H563ZI with the following architecture:PC ← USB ← NUCLEO-H563ZI ← SD CardThe SD Card and USB Device have both been tested separately, and each works correctly on its own.However, after integrating the two, I would like to use USB MSC to expose the SD Card connected to the STM32H563ZI as a removable storage device on the PC. The PC is currently unable to recognize the SD Card properly.I would like to ask if there is any example code or reference project for the STM32H563ZI that demonstrates USB MSC with an SD Card.Thank.

Hello,I apologize for any obvious questions, but I am new to CAN and STM32 programming. I have written a code that successfully sends CAN messages to a CANalyzer for data interpretation, so I believe I have enabled the CAN portion correctly. My next objective is to send a message from a CANalyzer to the MCU and have it turn an LED on when it properly received the message. I am using an evaluation board (STM32H7B3I-EVAL).I attached a copy of my main.c file.What I would like to know is how to enable an RX interrupt handler so that I can receive CAN data.What do I have to add to the main.c to make that happen?

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

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

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.
