+# stm32f413
+
+It also works with the following STM32F4 series.   
+- STM32F412
+- STM32F413
+
+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
+STM32F412/413 has two CAN ports.   
+These GPIOs can be used as CAN.   
+|CAN|RX|TX||

+|CAN1|PB8|PB9||
