Hardware

• FLEX Base Board hosting PIC33FFJ256MC710 microcontroller

• FLEX Thru Hole Daughter Board with FlexiPanel EasyBee IEEE 802.15.4 tranceiver module or alteratively a FLex Demo Daughter Board with abuilt-in ready to use ZigBee connector

Software

• Erika Enterprise Basic 1.4.1

PC Side Application
We used a PC connected to the FLEX Board as console. To visualize the data from the FLEX we used these softwares: Hyperterminal (Windows Systems) or Minicom (Linux). The setting was 115200 bit/sec without flow control.
The PC is connected to the FLEX by a RS232(COM) port. In our case by a USB/RS232 cable converter. The FLEX Board uses its UART1 to communicate with the PC. To interface the FLEX UART signals (0V/3.3V) and the PC RS232 signals (+12V/-12V), we used the IC MAX233CPP provided by MAXIM. This is not mandatory, one can use their own preferred line driver/receiver IC.
Flex Side Application
The CC2420/EasyBee can be connected through the FLEX Thru Hole Daughter Board or by the proper connector on the FLEX Demo Daughter Board . Note that, when the Flex Demo Board is used, both FIFOP and FIFO pins change, to accomodate this we must uncomment the following define statement in : #define FLEX_DEMO_BOARD.

#ifndef _CODE_H_
#define _CODE_H_
#include "hal.h"
#include "ee_console.h"
#include "radio_spi.h"
