Transmission!

[uaf5000]

Hello everyone,
Ive made a program to display some stuff on my lcd, being controlled by keypad. Now what i want is to serially transmit this data to Xigbee module which will then transmit it wirelessly to other module. What commands shall i add up in my program? Program is displayed below:

Define LOADER_USED 1

' Define LCD connections
DEFINE OSC 20
DEFINE LCD_DREG PORTD
define LCD_DBIT 0
DEFINE LCD_RSREG PORTE
DEFINE LCD_RSBIT 0
DEFINE LCD_EREG PORTE
DEFINE LCD_EBIT 1
DEFINE LCD_RWREG PORTE
DEFINE LCD_RWBIT 2
DEFINE LCD_BITS 8
DEFINE LCD_LINES 2
DEFINE LCD_COMMANDUS 2000
DEFINE LCD_DATAUS 50

        GOTO getkeyp            ' No keys down, go look again

gotkey4: ' Change row and column to key number 1 - 16              
        key = (col * 4) + (NCD (row ^ $f))
        'NOTE: for 12-key keypad, change to key = (row * 3)
        RETURN

        'NOTE: for 12-key keypad, change to key = (row * 3)
        RETURN                  ' Subroutine over

        
        END

P.S: The lines which are bold i want them to be transmitted.

Hi,

Too late for this evening ... your meal is somewhat burnt !!! ...

without knowing more about your ZigBee Module ... probably some serial output will be to use ...

Debug, Serout, Serout2 ... are the ones.

My Xbee is Xbee low power module. You can see more about it from here:

http://www.digi.com/products/wireles...e.jsp#overview

According to me i just have to serially send data to the radio and then it will transmit it. No more extra connections required. I just wanna know the particular commands for sending serial data (i.e through Tx and Rx pins of port C).

Regards.

How are you going to use the devices?

Do you have your own board or using the DIGI's dev kit?

The XBees require TTL Serial connection, not inversed by a driver when connecting to a microcontroller.

I suggest use the dev. kit to test them and set parameters, then connect to a micro.

Thanks Mack for the commands. But can u tell me precisely how to use them? Should there be some defines before i use these serial out commands? I have given the code, can you manipulate it accordingly?


I have Xbee XBIB board for one radio while ill plug the other radio in my own board where the microcontroller is placed (off course). I can set the parameters of my radio through this board and device software given by DIGI.
