Xbee API Method
PostPosted: Wed Sep 17, 2008 2:08 am     Reply with quote
Dear all

I wrote a source code for Xbee transceiver. I'm using API methods. Luckily, it is working. But, may be my code is look funny. Here i show my source code:

Transmit Request 16-bit:

Code:

void GXBeeTR()
{
unsigned int8 sd,lmsb,llsb,id,fid,damsb,dalsb,op,gid,data,csm;

sd = 0x7E;                          // (Byte 1)Start Delimiter
lmsb = 0x00;                        // (Byte 2)Length MSB
llsb  = 0x07;                       // (Byte 3)Length LSB
id = 0x01;                          // (Byte 4)API Identifier
fid = 0x00;                         // (Byte 5)Frame ID
damsb = 0x71;                       // (Byte 6)Destination Address MSB
dalsb = 0x76;                       // (Byte 7)Destination Address LSB
op = 0x00;                          // (Byte 8)Options (Please Refer Datasheet)
gid = 0x02;                         // (Byte 9)G-Xbee ID
data = value00;                     // (Byte 10)Gas Sensor Value

// (Byte 11)Checksum
csm = 0xFF - (id + fid + damsb + dalsb + op + gid + data);

putc(sd);putc(lmsb);putc(llsb);putc(id);putc(fid);putc(damsb);
putc(dalsb);putc(op);putc(gid);putc(data);putc(csm);
}



Receive Packet 16-Bit:

Code:


void GXBeeRP()
{
unsigned int8 x;

chksumRP = 0;

for (x=1;x<=11;x++)
{
   byteRP[x]=getc();
}
chksumRP = chksumRP + byteRP[4] + byteRP[5] + byteRP[6] + byteRP[7] + byteRP[8] + byteRP[9] + byteRP[10];
chksumRP = 0xFF - chksumRP;
CheckRP();
}



Can anyone help me to minimize the source code for both Transmit and Request? Very Happy Laughing

Thank You
