Hello, I am working on CAN communication which is between various STM32G474 controllers. As the product is power electronics, we are facing noise issue which disturb the CAN communication and hence product is not working properly. We are thinking to...
Hi, i need help with a strange behaviour of the FDCAN RX interrupt. I have 2 controllers which communicate with each other over CAN bus (Classic CAN). The first (my problem mcu) sends a command message and the second answers with 3 messages. The prob...
I am trying to find out whether is it possible to send 64bytes of data in one frame of Multiframe in CAN FD. i.e First frame will have 64 bytes, Consecutive frame will also have 64 bytes in STM32G0B1KBU6 basically in G0 series MCU
Hi guys! I have a custom board with 2x CAN FD transcievers (TCAN1057) and STM32G0B1 MCU. Everything works fine until i try to use hardware filters build into STM32. Whatever i do, filters don't pass any frame to RxFifo0/RxFifo1. The only way to recie...
Dear all,I'm struggeling to get FDCAN2 working on my board. I also use FDCAN1 - which is working pretty good.For FDCAN1 I selected the RxFifo0 and for FDCAN2 I selected RxFifo1.But for some reasons, I dont get the callback for HAL_FDCAN_RxFifo1Callba...
Hi!I have a problem with the canbus gateway project, I have a very good ring buffer that works without delays and transfers data between can1 and can2. All data copying is done through the main while loop where I check the buffers for can1 and can2 t...
Hello,On my project, I use FDCAN1 and FDCAN2. FDCAN1 is working perfectly fine.On FDCAN2, I can transmit data successfully (with the CAN ID 0xBEEF), but when I want do receive data, the Rx callback is never called, nor the IRQ handler (the CAN ID fil...
I am use nucleo-h503rb evk board and i am configure fdcan communication. I have mention below my code please see. I have did not comes output on FDCAN communication. please send me demo code for that
Hello everyone,I am working with the STM32G0B1KEU6 microcontroller, which comes in a 32-pin package featuring only ports A, B, and C. According to AN2606, the internal bootloader uses the following pins:FDCAN1_Rx pin: Input PD0, used in alternate pus...
