+This is code for the MAX1472 RF Transmitter EV-Kit. This program will record a
+temperature fom the MAX30208 EV-Kit, encrypt the data using the user-generated
+Symmetric key, apply forward error correction (FEC) encoding, and then send the
+message via the MAX1472 transmitter.
+
+ Hardware Setup and connections:
+
+ MAX32630FTHR-> MAX1472 Ev-Kit
+
+ 3.3V -> VDD
+ GND -> VSS
+ P3_1 -> Data_In
+ P5_2 -> ENABLE

+*******************************************************************************
+ MAX32630FTHR-> MAX30208 Ev-Kit

+ 1.8V -> VIN
+ GND -> GND
+ P3_4 -> SDA
+ P3_5 -> SCL
