Hallo

I am using LPC11c14 can open program in eclipse cdt.I am able to compile the program and while debugging the CAN-open is able to tranit the data but it is not able to go to the receive state.It goes directly to sleep state after transmitting.

Plz help me out

RAM = 0x10000050 Memory = 4k
Rom = 0x00000000 Memory = 32k

Thx in advance

So which code are you using?

Why has your LPC1114 only 4k?

How do you transmit data to your LPC?

Did you scope them (are they really on the BUS)?

Are they acknowledged?

Did you try Loop-back mode?

You are not providing much informations, so I would suggest to use LPC11C14 self test functions. They work without external hardware :)

I am using the example code of LPC11c14 taken from expresso.

Yes they are acknowledged

No, that's not the LPCXpresso example :exmark:

If your LPC is acknowledging messages, they are received :)

I really don't know what you are doing (except you are not using LPCXpresso).

All relevant issues have been discussed already (ROM-RAM...).

Since you don't answer questions I'll stop that here...

Good luck.

Here are some links to CAN example code.

Samples for each peripheral are included. See the CAN subfolder.

How to tranmit message from PCAN USB to LPC11c14

If you are using the example provided by LPCOpen (e.g. ~\LPCOpen_v1.03\applications\lpc11xx\examples\periph\periph_ccan_rom) then sending a message ID 0x400 - 0x4FF from your PCAN to the LPC11Cxx mcu, the message will be received and then sent back to the analyzer by LPC11C14 mcu.

How to send that message along with the interrupts

Kein Mensch versteht, was Du hier schreibst.
Selbst mit Google sollte es möglich sein, halbwegs verständliche Fragen zu formulieren. Wenn Du ernsthaft Antworten erwartest, könnte es helfen Dein Problem zu beschreiben und eine konkrete, nachvollziehbare Frage zu stellen.

I do no why are you not able to understand simple english?

Now I am able to send the message from PCAN to Microcontroller.This message is transmitted without the interrupts,But I need to transmit the message along with the interrupts.

So,I want to know how to transmit the message from PCAN-USB to Microcontroller with the interrupts.

Because that's no simple English, that's gibberish (Kauderwelsch)...

Even Google isn't understanding that:

That's nonsense. Messages are messages. There are no messages with interrupts or without interrupts.

So what is your question?

You know there is a User Manual for LPC11C14?
There is a chapter describing the interrupt controller (NVIC)...
(Chapter 6 of UM10398)

Are we talking about can_onchip sample?

/*CAN transmit callback */
/*[color=#f00]Function is executed by the Callback handler after
a CAN message has been transmitted[/color] */
void CAN_tx(uint8_t msg_obj_num){
  return;
}

Then it's this function:

/*[color=#f00]Function is executed by the Callback handler after
a CAN message has been transmitted[/color] */
void CAN_tx(uint8_t msg_obj_num){
  return;
}
