HIIf the CAN message ID set to FIFO0 is received, HAL_CAN_RxFifo0MsgPendingCallback will be called correctly.but,HAL_CAN_RxFifo1MsgPendingCallback is not called even if the CAN message ID set in FIFO1 is received.The following is strange.step1Send CA...

Hi I am using CAN in STM32F303RDT6.I am using HAL_CAN_AddTxMessage for CAN transmission.This function will send the data and return HAL_OK if the sending mailbox is free.However, although HAL_CAN_AddTxMessage returns HAL_OK, no message may actually b...

HiI would like to know about filter behavior in ID list mode and 16bit scale.I would like to receive 3 standard IDs.I know that with the combination of ID list and 16bit scale, I can receive 4 standard IDs. In this case, one will remain when setting ...

HiI don't know how to configure the CAN filter bank registers to receive extended IDs in ID list mode.Naturally, I read the manual, but there was no explanation.Even if there was, it would probably be difficult to understand. I found the following d...

HI The vector tables were different for FIFO0 and FIFO1.I thought vectors were common.

HiAdditional information.I monitored FMP1[1:0] of the CAN_RF1R register.After sending one CAN message from CANoe, FMP1[1:0] became 1. FIFO1 stores pending CAN messages.FULL1 and FOVR1 were also working correctly.At this time, FMPIE1 of the CAN_IER re...

Hi The problem was resolved by setting bit 4 of the CAN_MCR register to 0.I think that if you are using CAN, the initial value of bit4 should be "0".

@STOne-32 Thank you for your investigation.I was relieved that the results were genuine.I will check again to make sure there are no problems with the circuit or wiring, etc. as advised.

@STOne-32 I got a photo of the TOP marking.Is this a genuine product?
