Tedd OKANO / Mbed 2 deprecated PCT2075_Hello

Hello world code for PCT2075 and LM75B component class library. The PCT2075 is a temperature-to-digital converter featuring +/-1 degree-C accuracy over -25 degree-C to +100 degree-C range. It uses an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique with an overtemperature detection output that is a drop-in replacement for other LM75 series thermal sensors.

Dependencies:   PCT2075 mbed
