+# stm32f405
+I used [this](https://github.com/seeers/CAN-Bus-Arduino_Core_STM32) 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
+```
