掩码滤波器的发送和接收都需要配置 CAN_setupMessageObject这个函数么?
发送的CAN_setupMessageObject(CANA_BASE, 1, 0x18102700, CAN_MSG_FRAME_EXT,
CAN_MSG_OBJ_TYPE_TX, 0x0, CAN_MSG_OBJ_USE_EXT_FILTER ,
MSG_DATA_LENGTH);
接收的CAN_setupMessageObject(CANA_BASE, 2, 0x18102700, CAN_MSG_FRAME_EXT,
CAN_MSG_OBJ_TYPE_RX, 0x0, CAN_MSG_OBJ_USE_ID_FILTER|CAN_MSG_OBJ_USE_EXT_FILTER,
MSG_DATA_LENGTH);
在子环回模式下是不是不能使用掩码滤波呢?
如果可以使用掩码滤波应该如何配置呢?
