the microcontroller hangs.

Hangs where? If you understand where, you might be able to determine why.

I'm

 

using the

 

CAN1

 

and

 

CAN2

 

controller

 

micorcontrolador

 

STM32F207IG

. 

but I have

 

the following problem

:

Both controllers

 

are communicating

 

normally

, 

but when

 

the communication cable

 

from the controller

 

microcontroller

 

1

 

is

 

open

 

latch

.

Could someone help

 

me on this

 

problem,

 

is it possible to

 

enable and

 

disable the

 

CAN controller

??

Thank you.

Lock in the following function:

if((CAN_receive (1, &msg_rece, 15) == CAN_OK)) 

{

if(msg_rece.id==40)

{

Rece_CAN1 = msg_rece.data[0]; 

}

}

else {com_CAN_1=0, Rece_CAN1=0;}
