I am using 1769 to receive some message from 11c24. The message seems to have sent successfully from the 11c24, but I can't receive it on 1769. I modify the demo_aoa_basic project, here is the code from 11c24 and 1769:
Quote: 11c24
tx_obj.mode_id = 0x10;
tx_obj.msgobj = 0; // RPM
tx_obj.mask=0;
tx_obj.data[0]= CANPT_NODE_UNIQUE_ID;
tx_obj.data[1]=ID;
tx_obj.data[2]=data;
tx_obj.dlc =datalen+1;
(*rom)->pCAND->can_transmit(&tx_obj);
Quote: 1769
void canpt_task(void)
{
CAN_MSG_Type *msg;
if (!q_isEmpty()) {
msg = q_get();
int ID = msg->dataA[1];
int data=msg->dataA[2]; switch (ID){
case 0x01:
printf("%d \n",(&data));
break;
case 0x02:
printf("%d \n",(&data));
break;
}
}
if (numNodes > 0) {
checkIfNodesAlive();
}
}
the program seems to never entered the CAN interrupt handler on LPC1769 side. does anybody know the solution to this?
