MBED Snipet: Reading the WHOAMI register of an LIS302 accelerometer using SPI

.from: http://mbed.org/handbook/SPI?action=view&revision=442

#include "mbed.h"

SPI spi(p5, p6, p7); // mosi, miso, sclk
DigitalOut cs(p8);

Serial pc(USBTX, USBRX); // tx, rx

int main() {
    // Setup the spi for 8 bit data, high steady state clock,
    // second edge capture, with a 1MHz clock rate
    spi.format(8,3);
    spi.frequency(1000000);

    // Select the device by seting chip select low
    cs = 0;

    // Send 0x8f, the command to read the WHOAMI register
    spi.write(0x8F);

    // Send a dummy byte to receive the contents of the WHOAMI register
    int whoami = spi.write(0x00);
    pc.printf("WHOAMI register = 0x%X\n", whoami);

    // Deselect the device
    cs = 1;
