+Example Description
+
+This example describes how to use SPI read/write by mbed api.
+
+
+The SPI Interface provides a "Serial Peripheral Interface" Master.
+
+This interface can be used for communication with SPI slave devices,
+such as FLASH memory, LCD screens and other modules or integrated circuits.
+
+In this example, it use 2 sets of SPI. One is master, the other is slave.
+By default it use SPI0 as slave, and use SPI1 as master.
+So we connect them as below:
+    Connect SPI0_MOSI (PA_4) to SPI1_MOSI (PA_23)
+    Connect SPI0_MISO (PA_3) to SPI1_MISO (PA_22)
+    Connect SPI0_SCLK (PA_1) to SPI1_SCLK (PA_18)
+    Connect SPI0_CS   (PA_2) to SPI1_CS   (PA_19)
+
+After boot up, the master will send data to slave and shows result on LOG_OUT.
+
+Note:spi_idx should be asigned first in the initialization process,We use MBED_SPI1 for Master and MBED_SPI0 for Slave
