The objective of this lab is to design a point-to-point ZigBee network using the Xbee module. Each microcontroller will have a keypad and a two-line LCD display. When the operator types on the keypad, characters are displayed on one line of the LCD. When the operator hits the send key, those characters are sent and eventually displayed on the second line of the LCD of the other microcontroller. Debug the system in a bottom-up manner. Write simple main programs in the Rx and Tx systems to test the low-level functionality of the interface. Add appropriate debugging instruments, such as profiles and dumps. Connect unused pins from both devices to a single logic analyzer and record a thread profile (which program runs when) as a stream of data is passed from the Tx system to the Rx system. Write a main program to measure maximum bandwidth of your channel without using hardware flow control. Furthermore, you should determine which component limits bandwidth. Modify the transmitter so it outputs pseudo data as fast as possible. Modify the receiver so it does not display data on the LCD. Rather, the receiver will check for this pattern of characters and count the number of errors. Add minimally intrusive debugging instruments to determine if and where data is lost. Measure the maximum range of your system. In particular, find the maximum distance where the system performs reliable communication.
