&par Example Description

This example describes how to configure a communication the CAN in normal mode.
CAN1 transmit a message to CAN2. Then send the communication data between CAN1
and CAN2 to serial assistant through USART1.

&par Hardware Description

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled

The CAN connection as follows:
     _____________                                     ________________
    |             |                                   |                |
    |             |-PD0(CAN1_RX)  <--------->  CAN_RX-| CAN Transceiver|-CANH  <--------
    |             |-PD1(CAN1_TX)  <--------->  CAN_TX-|                |-CANL  <--     |
