+    Author: Allan K Liu
+    Original: Athanassios Mavrogeorgiadis
+    
+    Changes:
+    - Optimization for Low Power Consumption Operations
+    - GD0 as external interrupt, to bring MCU from deep sleep mode.
+    - GPIO setup
+    - Clock setup
+    - Event driven design
+    - ALOHA transceiver for channel access with RTS/CTS/ACK
+    - S-MAC
+    - Cloned high level designs from SimpliciTI.
+    - New CircularBuffer from mbed 5
+    
+    Status:
+    - CC1101 SPI access to regsiters from PARTNUM/VERSION to RCCTRL0 not stable
+    - PARTNUM ranges from 0x00/0xFF
+    - VERSION ranges from 0x0F/0x1F/0x4F
