CQ Publishing / Mbed 2 deprecated MARMEX_VB_Hello

A "Hello" program for MARMEX_VB library. This application may work 40pin type mbed platforms ;) This application expects to have the MARMEX_VB module on a "MAPLE mini type-B (MARM03-BASE)" baseboard (slot2) with a MARMEX_OB module (on slot1)

Dependencies:   MARMEX_VB NokiaLCD mbed

Sample code for MARMEX-VB (MARY-VB) camera module.

This is a very simple program just copies the data from camera to OELD.
