MSP430G2553 internal temperature sensor with LCD - Software code and Circuit diagram

Below is the Circuit Diagram and the Software Code for displaying the internal temperature sensor data on LCD.

Circuit Diagram:

Note: Connect a 47K ohm resistor between the RST pin and VCC (3.3V)
Vcc for MSP = 3.3V and Vcc for LCD = 5V
LCD used is JHD162A
