+/** An abstraction for an 18 bit ADC
+* @note Not quite sure this is thread or interrupt safe. Treat this as a standard mbed SPI object
+* There are mutex locks when the SPI bus is being used.
+* Example
+* @code
+* #include "mbed.h"
+* #include "AD7989_Driver.h"
+*
+* SPI spi(p5, p6, p7); // mosi, miso, sclk
+* DigitalOut cs(p8);
+* Digitalout convert(p9);
+* AD7989_Driver ADCDEV(&spi, &cs, &convert);
+* double voltage;
+* int main()
+* {
+* while(1)
+* {
+* voltage = ADCDEV.sample();
+* printf("Voltage = %f Volts", voltage);
+* }
+* }
