The SPI is configured to be in loop back mode and the received data is compared 40 * against the transmitted data, if they match the transmission is repeated and the LED 0 keeps flickering 41 * In case of any error or mismatch in received and transmitted data, LED 0 will stay On.<br> 42 * 43 * <b>Special connection requirements</b><br> 44 * There are no special connection requirements for this example.<br> 45 * 46 * <b>Build procedures:</b><br> 47 * Visit the <a href="http://www.lpcware.com/content/project/lpcopen-platform-nxp-lpc-microcontrollers/lpcopen-v200-quickstart-guides">LPCOpen quickstart guides</a> 48 * to get started building LPCOpen projects. 49 * 50 * <b>Supported boards and board setup:</b><br> 51 * @ref LPCOPEN_15XX_BOARD_LPCXPRESSO_1549<br> 52 * 53 * <b>Submitting LPCOpen issues:</b><br> 54 * @ref LPCOPEN_COMMUNITY 55 * @{ 56 */ 57 58/** 59 * @} 60 */ 61
