+ /** A class similar to AnalogIn, only faster, for LPC1768, LPC408X and KLxx
+ *
+ * AnalogIn does a single conversion when you read a value (actually several conversions and it takes the median of that).
+ * This library runns the ADC conversion automatically in the background.
+ * When read is called, it immediatly returns the last sampled value.
+ *
+ * LPC1768 / LPC4088
+ * Using more ADC pins in continuous mode will decrease the conversion rate (LPC1768:200kHz/LPC4088:400kHz).
+ * If you need to sample one pin very fast and sometimes also need to do AD conversions on another pin,
+ * you can disable the continuous conversion on that ADC channel and still read its value.
+ *
+ * KLXX
+ * Multiple Fast instances can be declared of which only ONE can be continuous (all others must be non-continuous).
+ *
+ * When continuous conversion is disabled, a read will block until the conversion is complete
+ * (much like the regular AnalogIn library does).
+ * Each ADC channel can be enabled/disabled separately.
+ *
+ * IMPORTANT : It does not play nicely with regular AnalogIn objects, so either use this library or AnalogIn, not both at the same time!!
+ *
+ * Example for the KLxx processors:
+ * @code
+ * // Print messages when the AnalogIn is greater than 50%
+ *
+ * #include "mbed.h"
+ *
+ * FastAnalogIn temperature(PTC2); //Fast continuous sampling on PTC2
+ * FastAnalogIn speed(PTB3, 0);    //Fast non-continuous sampling on PTB3
+ *
+ * int main() {
+ *     while(1) {
+ *         if(temperature > 0.5) {
+ *             printf("Too hot! (%f) at speed %f", temperature.read(), speed.read());
+ *         }
+ *     }
+ * }
+ * @endcode
+ * Example for the LPC1768 processor:
+ * @code
+ * // Print messages when the AnalogIn is greater than 50%
+ *
+ * #include "mbed.h"
+ *
+ * FastAnalogIn temperature(p20);
+ *
+ * int main() {
+ *     while(1) {
+ *         if(temperature > 0.5) {
+ *             printf("Too hot! (%f)", temperature.read());
+ *         }
+ *     }

+/**
+ * USBMSD class: generic class in order to use all kinds of blocks storage chip
+ *
+ * Introduction
+ *
+ * The USBMSD implements the MSD protocol. It permits to access a memory chip (flash, sdcard,...)
+ * from a computer over USB. But this class doesn't work standalone, you need to subclass this class
+ * and define virtual functions which are called in USBMSD.
+ *
+ * How to use this class with your chip ?
+ *
+ * You have to inherit and define some pure virtual functions (mandatory step):
+ *   - virtual int disk_read(char * data, int block): function to read a block
+ *   - virtual int disk_write(const char * data, int block): function to write a block
+ *   - virtual int disk_initialize(): function to initialize the memory
+ *   - virtual int disk_sectors(): return the number of blocks
+ *   - virtual int disk_size(): return the memory size
+ *   - virtual int disk_status(): return the status of the storage chip (0: OK, 1: not initialized, 2: no medium in the drive, 4: write protection)
+ *
+ * All functions names are compatible with the fat filesystem library. So you can imagine using your own class with
+ * USBMSD and the fat filesystem library in the same program. Just be careful because there are two different parts which
+ * will access the sd card. You can do a master/slave system using the disk_status method.
+ *
+ * Once these functions defined, you can call connect() (at the end of the constructor of your class for instance)
+ * of USBMSD to connect your mass storage device. connect() will first call disk_status() to test the status of the disk.
+ * If disk_status() returns 1 (disk not initialized), then disk_initialize() is called. After this step, connect() will collect information
+ * such as the number of blocks and the memory size.
