Hardware testing for M24SR-DISCOVERY demo PCB. as help to others
Set up to use MB1138 M24SR-DISCOVERY PCB http://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/st25-nfc-rfid-eval-boards/st25-nfc-rfid-eval-boards/m24sr-discovery.html with MBED system. based on https://developer.mbed.org/users/hudakz/code/STM32F103C8T6_Hello/ code and https://developer.mbed.org/users/wim/notebook/m24sr64-nfcrfid-tag-with-i2c-interface/ Which lead me to look at Peter Drescher's work on ILI9341 LCD controller
