STM32 FILTERING

Question asked by MK.ShaSha on Jan 6, 2016
I am using a STM32F302 custom made board.

 I have configured my filter banks as follows to configure message received from controller:



uint16_t STID4 = (0x02 << 9) | (0x18 << 3) | 0x06; //0x4c6
        sFilterConfig.FilterNumber = 3;
        sFilterConfig.FilterMode = CAN_FILTERMODE_IDMASK;
        sFilterConfig.FilterScale = CAN_FILTERSCALE_16BIT;
        //sFilterConfig.FilterIdLow = (GROUP2 << 9) | (Slave.MacId << 3) | GRP2_UNCONNECTED_REQ;
        sFilterConfig.FilterIdHigh = ((STID4 << 5) & 0xFFE0); 
        //sFilterConfig.FilterMaskIdLow = 0x7ff;
        sFilterConfig.FilterMaskIdHigh =0xFFE0;
        sFilterConfig.FilterFIFOAssignment = CAN_FILTER_FIFO0;  // Filter FIFO 0 assignment for filter x
        sFilterConfig.FilterActivation = ENABLE;
sFilterConfig.BankNumber = 2;


However, I am not able to obtain the MACID and MsgID that I am expecting from this filter configuration. Any suggestions?? Must I amend my filter configuration settings for this??
Also, does the way of configuring transmit message affect the receive message obtained?
Sorry, unclear about such details as I am not able to find these in ST's data sheet or user manual.
