Hi , i have keil MCB1000 boards with lpc11C14's on them . And CANopen network demo works properly which is given below

http://www.lpcware.com/content/nxpfile/an11238-lpc11cxx-canopen-network-demo-0

But there isnt any example or api about PDO in this demo . I have to implement 2 x TX PDO with PDO modes(Event/time trig. ,synch /Asynch) .

Is it possibble to do that with  onchip CANopen driver ? How ?

Thanks and Regards

I tested and understood SDO rx and tx with the LPC11Cxx demo, But this demo stack has only SDO functions and driver api, I want to implement PDO for the same is any one help me by providing sample code or implementation steps or functions.

I want to send 48(ADC data) bytes of data from Producer  node to Consumer node in regular interval, Please give your suggestion .

For the above task ,Is it SDO better (or) PDO ? How Many PDO i need to send 48 bytes of data? How can I set PDO mapping and parameters?
What is difference between producer node and consumer node?How to differentiate from code?

Any PDO Sample code ,Please share

Not all features of CANopen are implemented in the demo, but the most-used features of CANopen are supported:
• SDO expedited transfer: client & server.
• SDO segmented transfer: client & server.
• NMT: master, slave & boot-up.
• Heartbeat: producer & consumer.
The demo will demonstrate these features with the aid of a terminal program and the onboard LEDs and buttons.
[color=#f00]PDO transfer, synchronization, time stamp and emergency are not realized in the demo.

No, you have to implement PDO yourself   :((
