Posted on May 17, 2011 at 12:42Hello,
I succeed to send a CAN message in LoopBack mode. But when I try to communicate with an other microcontroller in Normal mode, TransmitMailbox is always equal to CANTXPENDING.
My code :
/* CAN cell init */
CAN_InitStructure.CAN_TTCM = DISABLE;
CAN_InitStructure.CAN_ABOM = DISABLE;
CAN_InitStructure.CAN_AWUM = DISABLE;
CAN_InitStructure.CAN_NART = DISABLE;
CAN_InitStructure.CAN_RFLM = DISABLE;
CAN_InitStructure.CAN_TXFP = DISABLE;
CAN_InitStructure.CAN_Mode = CAN_Mode_Normal;
CAN_InitStructure.CAN_SJW = CAN_SJW_1tq;
CAN_InitStructure.CAN_BS1 = CAN_BS1_8tq;
CAN_InitStructure.CAN_BS2 = CAN_BS2_7tq;
CAN_InitStructure.CAN_Prescaler = 1;
CAN_Init(&CAN_InitStructure);
/* transmit */
TxMessage.StdId = 0x01;
TxMessage.RTR = CAN_RTR_DATA;
TxMessage.IDE = CAN_ID_STD;
TxMessage.DLC = 2;
TxMessage.Data[0] = 0x01;
TxMessage.Data[1] = 0x00;
TransmitMailbox = CAN_Transmit(&TxMessage);
What are the other changes that I should do to pass in Normal mode?
