Apply even pressure to the Shieldboard edges until its leads are fully seat in the sockets. It should not require very muchpressure to install the Shield board; if the required force seems high, stop and re-checkthe pins are aligned properly.10.4 Out-of-the-box example codeThe pre-installed demo code runs a simple loop back test between the two CAN ports,using CAN protocol. The test requires a female to female, straight through connectioncable, connected between the two connectors on P3. As the test runs, user LEDs 1 and2 will blink alternately as a series of data blocks are transferred over the CAN ports; oncethe test completes successfully, LEDs 1, 2 and 3 will light and stay on. The test can berepeated easily by pressing the reset button on the LPCXpresso54618 board.If the test fails (as will happen if no cable is connected), LED1 and LED2 will blink briefly,then LED3 will light and stay on.Once drivers have been installed for the board, a virtual UART connection can be usedto see test progress. Refer to Section 3 for more information on driver installation andvirtual com port use.10.5 Other example codeThe MCUXpresso SDK includes drivers (called mcan drivers) and examples using pollingand interrupt methods.CAN-FD drivers from Embedded Systems Academy, compatible with the MCUXpressoSDK, are available separately under the Downloads tab of the CAN-FD kit pageand(http://nxp.com/demoboard/om13094) and also from the standalone shield boardpage (http://nxp.com/demoboard/om13099)Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.Downloaded from Arrow.com.
