Hello everyone, I'm a beginner in the FDCAN field with STM32. I'm trying to establish communication between two custom boards equipped with the same CAN transceiver. The mode is normal FDCAN. Here's the configuration of the FDCAN module for completen...
Hi all, For several days I have been trying to send and receive something via CAN, but I am unable to do so on the Riverdi LCD board. I read two posts here with similar problems and instructions and videos from ST, but it did not solve my problem. CA...
I am working in STM32F103C8T6, in that PA11/PA12- CAN RX/CAN TX pin connected with MCP2551's CTX and RTX. using DB 9 connector i cannot able to see the CAN data using ST-LINK V2. Kindly help me
I have a CAN Network with several nodes. Each nodes sends only a ACK when the message was ment for it. Lets say I have nodes A, B and C.Node A wants to send the message with ID 0x5. Node B ignores this message. Node C accepts this message (sends Ack)...
Hello everyone, I'm currently facing a puzzling issue with the Flexible Data-rate Controller Area Network (FDCAN) on the STM32H755ZI board. Despite using the exact same code that works flawlessly on the STM32H753 board, I am unable to get the FDCAN t...
Hi, i am looking for to use FDCAN by using GPDMA . I am using STM32H5 MCU for my application. it is not clear to me how can i use GPDMA with FDCAN. please guide me__PRESENT
Hello all, I am trying to receive CAN frames from a BMS, each frame is sent every 100ms and i am running the MCU's clock frequency at 180MHz (max speed) for Nucleo F446RE. Unfortunately, i am missing some frames randomly and it makes my stateflow n...

I made a driver for 1-Wire communication using UART in Single Wire Half Duplex mode.The communication is started by sending a RESET pulse that should last 480us. I read that to do it using UART I should set it up to 9600 baud, 8N1, then send 0xf0. Lo...
