How to use this example:

    1) After the RESET both LEDs are blinking fast.
    2) Press the BLUE BUTTON for start the CAN1 loopback test.
            If the CAN1 test is OK, the Green Led is on for 2sec
            If the CAN1 test is FAIL, the Red Led is on for 2sec
    3) After the CAN1 test, both LEDs are blinking fast.
    4) Press the BLUE BUTTON for start the SPI1 polling test , connect PA6 to PA7 (see below).
            If the SPI1 test is OK, the Green Led is on for 2sec
            If the SPI1 test is FAIL, the Red Led is on for 2sec   
    5) After the SPI1 polling test, both LEDs are blinking slowly.
            If you press the BLUE BOTTON both LEDs are on for 2sec
            The SW return to point n.5
