stm32f407

I used this as a reference.

Changes from the original

• frame format
  This example support Extended frame format: with 29 identifier bits.

• CAN port
  In this example, you can select the CAN port.

• CAN1 and CAN2
  In this example, you can use CAN1 and CAN2 port.

Remap CAN port

CAN1_RX mapped to PA11, CAN1_TX mapped to PA12
CAN2_RX mapped to PB5 , CAN2_TX mapped to PB6

CANInit(CAN_1000KBPS, 0);  // CAN_RX mapped to PA11, CAN_TX mapped to PA12

CAN1_RX mapped to PB8 , CAN1_TX mapped to PB9 (not available on 36-pin package)
CAN2_RX mapped to PB12, CAN2_TX mapped to PB13(not available on 36-pin package)

CANInit(CAN_1000KBPS, 2);  // CAN_RX mapped to PB8, CAN_TX mapped to PB9

CAN1_RX mapped to PD0 , CAN1_TX mapped to PD1 (available on 100-pin and 144-pin package)
CAN2_RX mapped to PB12, CAN2_TX mapped to PB13(not available on 36-pin package)

CANInit(CAN_1000KBPS, 3);  // CAN_RX mapped to PD0, CAN_TX mapped to PD1
