Hi

i am working with CAN of STM32F303K8  when i use 

status = HAL_CAN_Receive(&hcan, CAN_FIFO1, 100);

status always  HAL_TIMEOUT 

any help please 

#can #stm32-can #nucleo-f303 #stm32

Perhaps it is not receiving anything? Is 100ms long enough? Do you have some filter settings that would exclude all traffic? Do you have the wrong data rate set up?

i did use an 

filter 

and this my config

static CanTxMsgTypeDef TxMessage;

static CanRxMsgTypeDef RxMessage;hcan.Instance = CAN;hcan.pTxMsg = &TxMessage;hcan.pRxMsg = &RxMessage;hcan.Instance = CAN;hcan.Init.Prescaler = 2;hcan.Init.Mode = CAN_MODE_NORMAL;hcan.Init.SJW = CAN_SJW_1TQ;hcan.Init.BS1 = CAN_BS1_11TQ;hcan.Init.BS2 = CAN_BS2_4TQ;hcan.Init.TTCM = DISABLE;hcan.Init.ABOM = DISABLE;hcan.Init.AWUM = DISABLE;hcan.Init.NART = DISABLE;hcan.Init.RFLM = DISABLE;hcan.Init.TXFP = DISABLE;if (HAL_CAN_Init(&hcan) != HAL_OK){Error_Handler();}

Off a 36 MHz clock that would be 1.125 Mbaud. I don't see a filter in the PM
