#include "slave_2_tx_rx.h"
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8)

set_PAN_ID(PAN_ID); // Set PAN_ID
init_ZIGBEE_nonbeacon(); // Initialize ZigBee module
nonbeacon_PAN_coordinator_device();
set_TX_power(31); // Set max TX power
set_frame_format_filter(1); // 1 all frames, 3 data frame only
set_reception_mode(1); // 1 normal mode
delay_ms(10);
enable_int();
pin_wake(); // Wake from pin
enable_interrupts(GLOBAL);
enable_interrupts(INT_EXT);
ext_int_edge(H_to_L);
while (1)
{
enable_interrupts(INT_EXT);
}
} |
I do not know what the above command made the connection to the computer. To transfer data to and from RFD to Coodinator computer.
---> Who can help me ? what line code ?

Without seeing what's in these files...
#include <Coordinator.h>
#include "def_18f4620.c"
#include "slave_2_tx_rx.h"
... it's nearly impossible to help you.
It appears that a Zigbee module is connected via SPI mode to a PIC and that 'something' interrupts the PIC on the B0 pin,triggering the ISR,'stuff' is done including...
write_TX_normal_FIFO();
...which may or may not be sending Zigbee data to the PC..
again, very very hard to figure out unless the 3 files are shown.

and the code is appalling.
What is the point of sitting in a loop continuously enabling an interrupt. Why is it ever turned off?. Then the 'form' suggests this has possibly been ported from another compiler, by someone who has little or no knowledge of CCS. |
