first off
can_disable was designed to work with at90can seriers so might not work
with your uC
Other than the timer, I'm not sure what canfestival can do to wake the
controller up, but i have zero experience with sleep, so keep that in mind.
Before sleep I think it is best to set the node in stop mode. It just
disable processing and making of almost every type of canopen message, and
it will also tell the network that is has stopped.
On start, what you have done looks good to me.
best regards

Basically my question is what to do before to go in sleep mode and what to do
just after the wake up.
In the main I do:
switch(baudrate) // 0=100KBaud, 1=125KBaud, 2=200KBaud, 3=250KBaud,
4=500KBaud, 5=1000KBaud
{
case 0: canInit(100); break;
case 1: canInit(125); break;
case 2: canInit(200); break;
case 3: canInit(250); break;
case 4: canInit(500); break;
case 5: canInit(1000); break;
}
initTimer(); // Start timer for the CANopen stack
setNodeId(ObjDict_Data, nodeID);
setState(ObjDict_Data, Pre_operational); // Init the state
so, shall I have to do something before the sleep?
and after at the wake up?
Thanks in advance to anyone spends time in this.

R: R: R: R: Re: R: Re: R: Re: CanFestival on ATmega64M1 in Arduino IDE
Another question:
I've implemented the canFestival on a node which goes in sleep mode
(POWER_DOWN) when there's no power supply.
This device has a battery to keep the power supply on in OR with the main one.
Of course when the battery is on I need to put everything in deep sleep mode
with a consumption around 1.5uA @3V.
The issue is that sometimes, if I receive something on the bus, the node
suddendly wakes up from the sleep.
Therefore I need to avoid this bad situation in order to avoid the battery
discharge.
How can I disable the canbus just before to go in sleep?
Basically the sleep mode control is made in pin_change interrupt function.
ISR(PCINT1_vect) // interrupt service routine called when the sensor is
battery powered or not (LOWER PRIORITY THAN PCINT0_vect)
{
sleepMode = !digitalRead(V_supply);
if ( sleepMode )
{
Can_disable(); // doesn't work
#ifdef SERIAL_DEBUG
Serial.print('\0'); // print the NULL character to be sure that the TX
port pin (PB0) is LOW
#endif
cli();
stopADC();
sleep();
}
else
turnedOn = true;
}
I'm quite sure that there is something in the canFestival framework which put
the uC ON if something is received just before to go in sleep.
Any suggestion?

Sorry guys my fault.
The default nodeID is 0x01.
Everything works correctly
Thanks and sorry

I've found the issue.
It relative on how the objectdictionary .c file is created.
If I leave the file as it is
/* index 0x1200 : Server SDO Parameter. */
UNS8 ObjDict_highestSubIndex_obj1200 = 2; /* number of
subindex - 1*/
UNS32 ObjDict_obj1200_COB_ID_Client_to_Server_Receive_SDO =
0x600;/* 1536 */
The canbus node doesn't reply to any SDO request.
If I change it like this
/* index 0x1200 : Server SDO Parameter. */
UNS8 ObjDict_highestSubIndex_obj1200 = 2; /* number of
subindex - 1*/
UNS32 ObjDict_obj1200_COB_ID_Client_to_Server_Receive_SDO =
0x605;/* 1536 */
where 0x05 is the nodeID
I get the right reply from my node
Is this a bug on the object dictionary building procedure in the python
script?
Waiting a kind reply
Thanks

I did some other tests.
The issue seems inside the canDispatch function in states.c.
I'm using a pin as debug in order to understand if the code in some point
is executed
