Hi all,

I am using pic24 and microchip c compiler and the problem I am having is wh=
en I set the global variable to one as flag
same variable in other module doesn't get set after restart the pic. right =
after program it works but when I restart the board=A0
I can see it doesn't work.


in main I have:

volatile unsigned int zigbee_control_on=3D0;



uart3 ISR module I have:

extern unsigned int zigbee_control_on;


=A0if (zigbee_control_on =3D=3D 1)
=A0 =A0 {
=A0 =A0 do the code:
=A0 =A0 }

uart4 ISR module I have:

extern unsigned int zigbee_control_on;


=A0if (zigbee_control_on =3D=3D 1)
=A0 =A0 {
=A0 =A0 do the code:
=A0 =A0 }

based on my testing UART3 variable "zigbee_control_on"=A0never gets set aft=
er I restart the board.
on debug mode it always works because restart means reload. my question is:

1. what's the different between program and restart the pic?=A0
2. my purpose of the variable is when it is set to logic 1 fallow if statem=
ent. so far
in 2 modules =A0the flag is used. at this moment I am unable to read the va=
riable to=A0
understand what's happening. if I put a routine to read and send out when i=
t doesn't work
it is not sending anything. when I first program it will send correct info =
because it works right after
program.

any idea? or suggestion ?

thanks
